The name “Globemaster” has graced three
cargo aircraft, all of which were built at the Long Beach
plant. The first of the series was the C-74.
At the
beginning of WW II, the USAAF realized that with its global
military commitment, large, long range troop and cargo
transports would be needed. Early in 1942, Douglas Santa Monica
engineers laid out the design of Model 415, which would evolve
into the C-74, the world’s largest land-based transport at the
time. In June of that year Douglas received a contract for 50
of the aircraft, with authorization for production to begin
without an X or Y prototype program.
The
specifications called for four
Pratt & Whitney R-4360 Double Wasp 20 cylinder engines rated
at 3,000 hp, and an 86 ton takeoff weight, resulting in a
maximum range of 7,250 miles, and a payload of 125 troops or
48,000 lbs of cargo. The
laminar-flow wing featured full span flaps (the outer
sections acting as ailerons). An innovative hoist system was
developed to take cargo up into the main cabin from underneath
the fuselage. The first planes off the line had the distinctive
“bug-eye” canopies for the pilots as did its contemporary Santa
Monica development, the XB-42. And, in both cases, a
conventional cockpit was retrofitted to permit better crew
communication at the price of some additional drag.
The first
C-74 made its maiden flight at Long Beach Municipal airport on
September 5, 1945, just days after Japan surrendered and WW II
ended. It thereafter became a victim of the massive cutbacks in
airplane production with only fourteen of the fifty aircraft
remaining on contract with the government.
Douglas
found some interest in a commercial version of the C-74 when, in
late 1945, Pan American place an order for 26 passenger planes,
tentatively named the DC-7. But in 1947, the airline cancelled
the order, believing the airplane was too large for their
forecast demand and because without military production to share
fixed costs, the price of the commercial airliner became too
high.
Of
the fourteen airplanes built, one was a static test article, the
second crashed on a company test flight: Only twelve C-74s saw
service. During the
Berlin Airlift, “Operation Vittles” the C-74 was briefly
flown into Gatow and Templehof. Air Force ship 42-65414 set a
record of delivering 1,234,000 lbs of cargo to Berlin in just
six weeks. On one day, September 18, 1948, 414 flew six round
trips carrying a total of 250,000 lbs of coal. The next year,
the same airplane set a record by flying 103 passengers non-stop
from Mobile, Alabama to Marham, England. One airframe was
modified to become the
YC-124 for test purposes. Subsequently, it was burned up in
a fire drill gone bad.
By 1950,
the
C-124 Globemaster II was being delivered, and its older
sister was being retired from service. A few airplanes were
declared surplus and were picked up by cargo airlines, but the
bulk of the (Globemaster I) fleet was dismantled at
Davis-Monthan AFB. No C-74s have survived until today.

Aircraft since 1920 formed part of the basis for this

RoundUp issue number 120 in February 2003)

The Douglas B-19
(November 2010)
In 1935 the Army Air Corps initiated a secret
“Project D,” intended to develop an experimental airplane to
“investigate the advancement of military aviation to the maximum
feasible distance into the future.” The resulting competition
was between Douglas and Sikorsky. After both
companies built mockups of their designs for the project, now
known as the XBLR-2 (the XBLR-1 was the Boeing
(search)
B-15). The XBLR-2 was the Sikorsky design study. The
contract to build a prototype was won by Douglas. Design work
proceeded slowly because of a limited War Department budget. In
fact, even after getting a loan from the government to keep
things going, the company was spending large amounts of its own
funds to further the program. By 1938 Douglas even recommended
cancellation of the contract because of the cost and the fact
that its technology was getting to be obsolete. But the
government insisted that work should continue. At this point,
the project was designated as the XB-19 and was continuing at a
snail’s pace.
By 1941, when construction was completed, the
XB-19 had lost some of its military significance and its secret
classification was removed. However, the airplane was a very
impressive achievement - the largest American airplane built
until the B-36 came on the scene in 1946. And the general
public loved it: “The Guardian of the Hemisphere,” as it was
called, inspired “B-19 Burgers” and was used for many promotions
of very large things.
Large it was. The bomber’s wingspan of 212
feet, maximum gross weight of 162,000 lbs and wheel diameter of
8 feet would elicit gasps of amazement from people who saw it
for the first time.
After a couple of false starts in May 1941, the
XB-19 made its first flight on June 27. Major Stanley M.
Umstead sat in the left seat and flew a 55-minute flight from
Santa Monica to March Field in Riverside, California. With
secrecy lifted, the first flight became a public event and
attracted hundreds of spectators who lined the runway at Clover
Field to watch the big plane lumber into the sky.
Contractor and Air Corps testing was begun at
March Field, but after Pearl Harbor the B-19 was camouflaged and
equipped with live ammunition for its guns and ferried to
Wright Field (search)
in Dayton, Ohio in January, 1942 to continue the test program
which lasted 18 months.
Valuable information was collected in the
tests, which contributed to the designs of the B-29 and B-36,
but the B-19 itself was destined for an ignominious end.
Because the radial engines were subject to running hot,
requiring the use of cowl flaps in cruise, the speed of the
XB-19 was degraded from 224 mph to 204 mph. The Air Corps
modified the ship by installing four Allison V-34200
liquid-cooled engines (increasing cruise speed to 265 mph) and
converted the bomber to a cargo airplane. The designation was
changed to XB-19A, and the airplane saw some duty as a
general-purpose transport during WWII.
Finally, in August 1946 the XB-19A made its
last flight to Davis-Monthan Field
(search)
where it was stored and scrapped in1949.
For all its
fame, the B-19 was a financial debacle for the Douglas Company.
When the government accepted the aircraft in June 1942, it made
a payment of $1,400,064. But the company had spent an
additional $400,000 on the project which was never recovered
except, perhaps in part, in the form of recognition for having
built the “World’s Largest Airplane,” the admiration of the
public, and the pride of the employees.

Editor's Note - Back in May, I
received an email from Steven Lund. He was Director of
Air Safety Investigations in Flight Operations at ( DAC) Long
Beach before he retired in 2002 after 32 years with MDC/ Boeing.
In retirement, Steven was encouraged to take up writing as a
hobby and enrolled in a college writing class. He has published
several articles in the International Society of Air Safety
Investigators annual newsletter and has submitted four
book-length manuscripts to a publisher.
For this
issue of Roundup, we are using the “Just the Other Year”
space to give our readers a sample of Steven’s work: The
following is his report on the American Airlines Chicago crash
in 1979. All of us who were
working at that time will remember the terrible news of the
crash and the ensuing months of unwarranted criticism of a fine
airplane that irreparably damaged its reputation.
-ed.
A Black Day
It was the afternoon of May
25th 1979 when DAC’s Office of Air Safety Investigations’ phone
rang with the National Transportation Safety Board’s (NTSB)
communication center operator reporting that an American
Airlines DC-10, Flight 191, from Chicago to Los Angles
had just crashed after liftoff—killing all 258 passengers and 13
crew on board, and two on the ground.
The initial investigation
immediately revealed the No.1 (left) engine and its pylon had
obviously separated from its wing mount, because the engine and
pylon assembly were found on the takeoff runway and a Chicago
Tribune’s front page photo showed the left engine missing before
impact. The accident brought immediate, ruthless criticism from
the media, because it was the 4th fatal accident involving a
DC-10 at the time, totaling 662 fatalities.
The NTSB
Investigation team supported by their requested concern parties
from:
•. The
Airline Pilot’s Union
• American Airlines Safety Department executives
• Engine manufacture engineers
• Flight Safety experts from DAC
(They) Quickly learned that the
forward pylon / wing attach bolts were missing and the aft pylon
wing-attach bulkhead was severely damaged.
The
bolts were eventually found fractured, either from fatigue or
overload—impossible to ascertain without painstaking laboratory
microscopic examination. Nevertheless, likely due to the
extreme media pressure, the NTSB media spokesperson held the
bolts up as a probable cause of the accident. This hasty non
sequitur generalization was proven totally incorrect; when
subsequent laboratory examination clearly revealed the forward
wing/pylon attached bolts had failed due to being overloaded
after the aft pylon attach bulkhead failed because of a massive
pre-existing crack. The engine’s takeoff thrust vector then
pivoted the engine/pylon assembly up and over the wing—
overloading the forward bolts.
(Diagram - wikipedia. See
link below)
Still under aggressive media
pressure, the NTSB issued a safety recommendation to the FAA to
inspect all DC-10 aft pylon bulkheads for possible cracks after
officials discovered that a maintenance procedure caused the
cracked bulkheads: American Airlines mechanics had removed the
engine and its pylon together, rather than removing the engine
from the pylon then the pylon from the wing, as recommended by
DAC. This was done using a forklift and the pylon was
inadvertently cracked in the process.
The post accident inspection
procedure found one cracked bulkhead in a plane that was
mistakenly reported already inspected only a few flights prior
to the crack’s discovery. This hasty false inspection report
caused unwarranted serious concern within the already panic
stricken FAA officials, causing them to revoke the DC-10’s
Airworthiness Certificate; hence grounding the entire fleet, on
June 6th 1979.
Cooler heads finally prevailed
when officials came to their senses about the unauthorized
maintenance procedure actually causing the aft bulkhead crack
rather than the few flights mistakenly reported crack happening
just before a crack was found. In November 1979, the FAA fined
American Airlines $500,000 for using this faulty maintenance
procedure.
The final NTSB report
officially listed the most probable cause of the accident as
“…maintenance induced crack…” The aircraft resumed service after
several additional safety enhancements were accomplished and its
safety record was ultimately proven comparable or better than
all other 2nd generation jet airliners. [SSR

Douglas A4D (A-4) Skyhawk
(April 2010)
| |

Photo - The Boeing Company |
|
By the early 1950’s, the El Segundo Douglas
plant had achieved a solid reputation as a supplier of combat
aircraft to the U.S. Navy. The F3D Skynight (Link)
and the F4D Skyray (Link)
were among the first carrier-based jet fighters, and the
jet-powered A3D Skywarrior (Link)
was entering service. A jet successor to the AD
Skyraider (Link),
the workhorse piston-powered attack and nuclear bomber,
was needed for the Navy to move entirely into the jet age with
its combat assets.
In 1952, Ed Heinemann (Link),
the El Segundo chief engineer, put together a surprising
preliminary design – an airplane exceeding the mission
requirements specified by the Bureau of Aeronautics (Link),
but with an operating weight of less than half the limit listed
in the Navy’s requirements. Despite some skepticism by BuAer,
further design work was requested, thus setting in motion the
development of the A4D Skyhawk.
Although Skyhawk was its formal name, to
those Naval aviators who flew it and those who maintained it,
the A4D held a special charm. In the fleet, it was “Heinemann’s
Hot Rod”, “Scooter”, and the “Bantam Bomber”, and it service
faithfully for four decades.
In the beginning, in June 1952, Douglas was
awarded a contract for one XA4D-1 and one static airframe. A
further batch of nineteen pre-production A4D-1 Skyhawks were
ordered prior to first flight on June 22, 1954 when Bob Rahn
took the XA4D-1 off from the runway at Edwards AFB (Link).
The A4D design was based on simplicity.
Heinemann’s layout man, R.G. Smith, and project engineer Ben
Collins, stressed a lightweight, yet strong airframe. The wing
configuration called for a delta shape with a span of only 27
ft. 6 in., which permitted the elimination of wing folding
mechanisms. High lift devices were leading edge slats and
trailing edge split flaps. Armament consisted of two 20mm
cannons mounted in the wing roots. Three external racks were
provided which could carry weapons or drop tanks.
Early A4Ds were powered by a single Wright
J65-W4 or –W4B (non-afterburning) engine rated at 7,700 lbs
static thrust. Performance of the Skyhawk proved it was worthy
of the nickname, “Heinemann’s Hot Rod”, when in October, 1955,
the second preproduction airplane flew to a record speed of more
than 695 mph over a 500 km course.
In 1956, the A4D-2 was introduced. This
improved model featured an in-flight refueling probe and an
up-graded J65 powerplant. The A4D-2N appeared in 1959. This
version was given terrain clearance radar and an improved
autopilot, affording the airplane all weather and night
operating capability. A LABS (Low Altitude Bombing System) was
added, and the J65’s thrust was eventually increased to 8,500
lbs.
In 1962, after a total of 638 A4D-2Ns were
built at El Segundo, the production line was moved to the Long
Beach plant. That same year, the DoD standardized the
designations of aircraft across the services, giving the Skyhawk
a new type name: The A-4.
What would have been the A4D-5, now the
A-4E, was fitted with the Pratt & Whitney J52 engine with 8,200
lbs thrust and 27% lower fuel consumption. The 499 A-4Es had
two additional wing store pylons. This was in recognition of
the changed role of the airplane, from its nuclear strike
capability to the mission of air support and conventional
ordnance delivery. The airframe was modified to permit a second
pilot seat and became prototypes for the trainer version of the
Skyhawk. In 1966, the first of 238 production models, TA-4F,
was delivered to the Navy. The TA-4 featured the newly
Douglas-developed Escapac ejection seat for both crew members.
This seat, with zero-zero capability (zero airspeed and zero
altitude), was adopted for subsequent Skyhawks, and eventually
became a standard seat for both Navy and Air Force aircraft.
Also in 1966, the last attack version, the
A-4F, with its 9,300 lb thrust J52-P-8A engine, improved
maneuverability, and a new avionics suite housed in a hump atop
the fuselage. 147 of the model were built.

By 1970, the Marines started flying the new
A-4M variant. This model was adapted for electronic warfare,
and featured a high-capacity electrical system, larger
ammunition capacity, and engine thrust uprated to 11,200 lbs.
The list of variations in the production and in-service
modifications of the A-4 line is a long one. It was common to
give an identifying model number to A-4 aircraft sold abroad,
and many countries adopted the Skyhawk: Australia (A-4G),
Israel (A-4H), New Zealand (A-4K), Kuwait (A-4KU), Argentina
(A-4P), and Singapore (A-4S).
Skyhawks were widely used in combat. U.S.
Navy and Marine Corps raids into North Viet Nam from carriers at
Yankee Station in the Gulf of Tonkin, and close air support
missions flown from Dixie Station and into targets south of the
DMZ, were commonly performed by Navy and Marine A-4s.
With its agile maneuverability, Skyhawks
were selected to fly in the aggressor role at the famous Navy
Fighter Weapons School and Top Gun
(Link) air
combat program. A-4Fs were adopted by the Navy’s show team, the
Blue Angels (Link),
at their aircraft replacing the F-4 Phantoms in 1974.
The Skyhawk
remained in production until 1979, with a total of 2, 960
aircraft built, including 555 two-seaters. The last production
A-4, and A-4M delivered to Marine squadron VMA-223, had the
flags of all nations who had operated the A-4 series aircraft
painted on the dorsal avionic hump.

The McDonnell Douglas MD-95/
Boeing 717

Photos by JF Hennessy
As we
have seen in the last two issues of Roundup, the
DC-9/ MD-80/ MD-90 progression
of twinjet transports followed the logical pattern of growth in
size and performance enabled by engine developments: The DC-9-10
had a capacity of 90 seats; the MD-90 could carry 172
passengers. Over time, each later model took advantage of
improvements in systems and flight management technology.
By the
early 1990s, it became time to apply those advancements in the
state of the art to the original target market for the airplane
- short to medium range routes with modest size requirements.
It was decided to return to the DC-9-30 capacity and wing
configuration and reap the benefits of two decades of technical
progress.
McDonnell Douglas first announced the
MD-95 at the Paris Airshow in June 1991. But it was
not until October 1995 when ValuJet (now AirTran Airlines)
ordered 50 and optioned 50, that the company gave the program
the green light.
For a
suitable engine, MDC had chosen the new BMW Rolls-Royce (now
just Rolls-Royce) BR715 for the proposed MD-95. Honeywell was
selected to supply the integrated flight management system,
featuring six LCD screens in the thoroughly modern cockpit. The
100-seat cabin interior was updated using designs similar to the
MD-90.
After
the 1997 Boeing/McDonnell Douglas merger, the company decided to
continue to market the new twin and changed the aircraft name to
Boeing 717-200. (Boeing had
previously used the “717” model number to identify its C-135 and
KC-135 family.)
First
flight took place on September 2 1998, and certification was
awarded on September 1 1999 while the first delivery, to AirTran,
was on September 23 that year.
Two
types were offered: The standard 717-200BGW (Basic Gross Weight)
and extended range 717-200HGW (High Gross Weight) versions.
Companies participating in 717 production include Alenia
(fuselage), Korean Air (nose), AIDC of Taiwan (empennage), Shin
Meiwa of Japan (engine pylons and horizontal stabilizers),
Israel Aircraft Industries (undercarriage), and Fischer of
Austria (interior). Final assembly was at Boeing's Long Beach
plant, in the same building that the DC-9 and MD-80 were built
in.
Among
717 customers were, AeBal, AirTran, Bangkok Air, Bavaria
International Leasing, Hawaiian Airlines, Impulse Airlines,
Midwest Express Airlines, Olympic Aviation, Pembroke Leasing,
Qantas Link, Siam Reap Air, Trans World Airlines, and
Turkmenistan Airlines
The 717
had suffered from slow sales throughout its history, with 156
planes ordered. In January 2005, Boeing announced that it would
cancel the 717 program after completing all outstanding orders.
On May
23rd, 2006 an estimated 3,000 active and retired Douglas,
McDonnell Douglas, and Boeing employees gathered at the West
ramp and witnessed the delivery of the 155th and 156th B-717s
which were the 15,598th and 15,599th airplanes built at the Long
Beach plant. The CEOs of AirTran
and Midwest Airlines were on
the dais to accept these last airliners to be built in
California.
From
1963, when the Douglas Company launched the DC-9, to 2006, with
the deliveries of the final two 717s bearing the Boeing brand
name, the 43-year production of twin jets amounted to 2,449
twinjets. Most of them carried the McDonnell Douglas
nameplate. They were all rugged, reliable, and profitable
airplanes. A comparison of the original DC-9-10 with the B 717
is a demonstration of the technical leaps forward over four
decades: Three generations of engine efficiency improvements
from the JT8D-5, through the re-fanned JT8D-200 series, to
modern high bypass IAE and BMW/RR powerplants; cockpit
technology growth - from electromechanical, to digital, to an
advanced six LCD screen Honeywell EFIS flight deck; and
continued attention to the detail required for ease of
maintenance and reliability.
And so the curtain fell on the production of commercial aircraft
at Long Beach. It is fitting that the final airplanes off the
line were among the very finest products ever built. To all of
you who participated in the traditions and excellence of the
storied DC, MD and Boeing aircraft built there, a fond “Well
Done!”

The McDonnell Douglas MD-80
(
December 2009 )

The
DC-9 program (see: Sept. 2009 Roundup) was a successful
execution of the Douglas product strategy of growth in model
size and performance capability as engine developments allowed.
When the series 50 was produced, the growth in passenger
capacity reached 139 - a 54% increase over the 90-seat Series
10. The JT8D engine thrust had grown from 14,000 lbs to 16,000
lbs. In all, 976 DC-9s, of all models were delivered. Further
growth of the twinjet would require more power from quieter
engines and a larger wing.
Development
of the new Pratt & Whitney JT8D-200 series higher bypass engines
triggered early studies including designs known as DC-9-55 and
DC-9-60. The new type would into service in 1980, therefore,
the project was branded the "DC-9 Series 80".
The new model
featured a fuselage 14 feet 3 in. longer than the DC-9-50,
allowing an all-coach seating capacity of 172 passengers. The
DC-9 wings were modified by adding sections at the wing root and
tip for a 28% larger area. Up front, the cockpit was modernized
to include upgraded avionics and flight management systems. The
series was certificated to meet Stage 3 noise requirements.
Swissair
became the launch customer for the the Series 80 in October
1977 with an order for 15 plus an option for five. The Series 80
first flew on October 19, 1979. in July 1983, MDC dropped the
DC-9 designation and changed the model name to to MD-80.
Four MD-80 models
-- the MD-81, MD-82, MD-83, and MD-88 -- are 147 feet, 10
inches long and accommodate a maximum of 172 passengers. The
MD-87 is 130.4 feet in length, with a maximum passenger capacity
of 139. Wingspan for all models is 107 feet, 10 inches. The
MD-80's nonstop range is from 1,500 to 2,700 statute miles,
depending on the model. MD-81 maximum takeoff weight is 140,000
pounds; MD-82 and the MD-88 are certified at 149,500 pounds. The
longer range MD-83 has a takeoff weight of 160,000 pounds.
MD-87 MTOGW is 140,000 pounds, with an option to 149,500 pounds.
MD-80s were in
production for more than 19 years. The delivery of the final
plane, number 1,191, was in December 1999. (35 MD-80 airplanes
were assembled and operated in the People's Republic of China.)
Prime customers for the MD-80 series were Swissair and Austrian
Airlines, the original launch orders, and large fleets were
acquired by TWA, American, Delta, Alitalia. and SAS.

The McDonnell Douglas MD-90
(
December 2009 )

The MD-90
has an overall length of 152 ft. 7 in. and a wing span of 107
ft. 10 in. Payload capacity is 172 passengers and 1,300 cu. ft.
cargo volume.
The MD-90-30, with
a maximum takeoff gross weight of 156,000 lb. carries 155
passengers approximately 2,400 st. mi.. The MD-90-30ER with
increased maximum weight of 166,000 pounds and an additional
565-gallon auxiliary fuel tank, has a range of 2,750 mi.
With a takeoff
thrust of 25,000 pounds, the MD-90-30 can use runways as short
as 5,000 ft. on a typical 550-mi. flight with a full passenger
load. At maximum takeoff gross weight, the MD-90-30 requires
only 7,100 feet of runway. A 28,000-pound optional takeoff
thrust rating is available for enhanced takeoff performance.

The
Boeing Realty Company (search)
and its contractors are making slow progress in
redeveloping the land in Long Beach once occupied by the Douglas
Company. The approximately 265-acre site is still mostly dirt,
but a small enclave of buildings has gone up, located at what
will be the corner of (Jim) Worsham Ave. and (Carl)
Cover St. The building interiors remain to be finished once
occupants are lined up. A recreation of the Douglas
“First-Round-the-World” globe is complete and in place.
Douglas Park (search),
as the overall site is called, will eventually be home to
industrial, office and retail operations and an upscale hotel.

Final UPS DC-8 Flight

The final
DC-8 flight operated by UPS Airlines touched down on the
morning of May 12 at Louisville International Airport. The plane
received a water cannon tribute as it rolled down the runway.
The first UPS Airlines DC-8 flight, from Louisville to
Milwaukee, occurred on Feb. 1, 1988.
UPS
Airlines, the Louisville-based division of Atlanta-based
shipping giant United Parcel Service Inc., made the decision in
April to retire its fleet of 44 DC-8s as part of a cost-cutting
initiative. UPS once owned 49 DC-8 aircraft, but sold five over
the years.
Of the 556
DC-8s originally produced, 97 remain in service following the
retirement of the fleet. The company now operates about 220
planes and charters an additional 309 planes, according to a UPS
fact sheet.
-Business Journal - Louisville
“What
other aircraft could lose all hydraulic and all electric
capabilities and still take you across the pond happily.
Remember: The DC-8 is never broken, just misunderstood. A real
tribute to the pocket protector engineers whose slide rule was
their computer.”
Daniel Cole, A-300 Captain
“The
Electric Jet pilots made fun of the DC-8, but it was like a
Timex watch, it took a licking and kept on ticking.”

Guillot, DC-8 Captain Retired


Douglas DC-3 Monument Park Opens
More than 1,000 active and
retired Douglas heritage employees and their families convened
at the Santa Monica Airport
(search)
on Saturday, March 21, to participate in the unveiling of
a new monument park honoring Donald W. Douglas, the company he
founded, and his famed DC-3 airplane.
The
public site, located at Airport Ave. and Donald Douglas Loop
Road, offers a restored DC-3 elevated on pedestals, a life-sized
statue of Donald W. Douglas
and his favorite dog “Bar,” a Founders’ Wall listing more than
1,000 contributors to the project, and kiosks with information
on the history of the Douglas Aircraft Company. A new Museum of
Flying is slated to open adjacent to the monument in 2010.
At the opening day celebration,
Victoria Douglas Thoreson
unveiled the statue of her grandfather, along with the aid of

CFM International is a 50-50 joint company...
. . .
of Snecma, France and GE Aviation, U.S.A. It was formed 35 years
ago in 1974 to develop a “ten tonne” turbofan engine that
didn’t have a specific application at the time, but seemed to be
an attractive follow-on for JT3D and JT9D powerplants in the
20,000 lb thrust class. General Electric's F101 engine, which
was developed for the B-1B Lancer strategic bomber was used as a
basis for the high pressure compressor, combustor and high
pressure turbine, Snecma was responsible for the fan, low
pressure turbine, the gearbox and the exhaust systems.
After some
eight years of development spent on the project without a single
order for it, the CFMI enterprise was just weeks way from being
dropped when the DC-8 Super Seventies came along.
The
CFM56-2, at between 22,000 lbs and 24,000 lbs static thrust was
the first of the series and used on the DC-8 retrofit program.
Eventually, more powerful versions were developed with the
CFM56-5C rated at as much as 34,000 lbs (used on the Airbus
A340-200).
A clipped
fan version of the engine was adopted for Boeing 737 and Airbus
A320 airframes. USAF re-engined KC-135s using the CFM engine.
In February
19, 2008 CFMI announced that it had would deliver the 19,000th
CFM56 engine that year, making the “ten tonne” engine market
exceed the most optimistic projections 35 years ago.
. . . And the DC-8 started it all.

The DC-8 Super Seventy Series
The end of the line.
On May 12,
1972, the final DC-8, a model -63 for SAS, was delivered from
the Long Beach factory. As was the case with all early
jetliners, it was noisy by modern standards. With expanding
jet fleets going into service at the time, aircraft noise was
increasingly becoming a serious problem. Because of their
increased takeoff weights and higher thrust, the new 60-series
DC-8s, in particular, prompted legislation for aircraft noise
standards in many countries. The New York Port Authority
(search) had
already adopted takeoff weight restrictions aimed at the
stretched DC-8s.
Douglas,
now a division of McDonnell Douglas, had committed to build the
new DC-10 in 1968. With high bypass ratio engines, the new
wide-body transports could easily meet existing and proposed
noise limits. The company was unable to commit further
investment to modify existing DC-8s even as several airlines had
enquired about noise reduction alternatives.
Aftermarket
hushkits were offered by third parties, but while they
represented a lower investment for the operators, they were only
marginally effective at noise abatement and caused some
performance degradation. A better solution was to re-engine
late model Series 60 airframes. United, Flying Tigers, and
Delta joined to begin a joint study of re-engine options. A
newer engine would mean a increase in efficiency and performance
at the same time it would deliver an acceptable noise output.
There were three suitable engine choices - the Pratt and Whitney
JT8D-200, the IAE V-2500, and the General Electric - Snecma
CFM56. In 1977, several retired McDonnell Douglas executives
led by Jack McGowen, formed
Cammacorp as a contractor for DC-8 conversions and retrofitting
projects. With the concurrent approval of the airlines and the
considerable participation of GE, Cammacorp selected the CFM-56
engine to power the modified DC-8s. As well as being 70% quieter
and more powerful, the CFM56 was roughly 20% more fuel efficient
than the JT3D, thereby reducing operating costs and extending
the range of the aircraft.
The program
to re-engine the DC-8 was launched in 1979 after United Airlines
ordered conversion of its DC-8-61s. Delta and Flying Tiger
followed soon thereafter. The conversion program was extended to
other Series 60 aircraft, which were renamed the -71, -72, and
-73.
MDC acted
as a vendor to Cammacorp, providing engineering data and design
consulting on a contracted basis. Airframe modifications were
done at the McDonnell Douglas plant in Tulsa. Grumman Aerospace
was contracted to supply engine nacelles and the redesigned
pylons that were required for the new engine.
First
flight took place on August 15, 1981. Flight test proved that
the re-engined DC-8 met or exceeded performance and noise level
estimates. First delivery took place in March, 1982.
A total of
110 Super -70s were delivered: 53 -71's, 7 -72's, and 50 -73's.
The final airplane off the line was a -72 for NASA in 1986 after
which Cammacorp closed its doors. Product support is provided
by the participants in the program.

The Douglas DC-8 Super Sixties

In the
first years of flying the DC-8
(search)
, it became evident
that the 707 (search)
had a range advantage which, together with its earlier
availability, made the Boeing product the airline market leader.
By the early 1960s the DC-8 program was in danger of closing
with fewer than 300 aircraft sold. Clearly, something had to be
done to increase market share.
At the time,
DC-8 performance improvements had been under consideration: A
six foot span increase, re-designed engine pylons that attached
to the wing’s lower surface only, and modified engine nacelles
to duct the fan outflow to the tailpipe, held the promise of
substantially lower drag and therefore, better miles per pound
of fuel.
Another
benefit of the Douglas design that could be exploited was that
the DC-8 had been planned to allow the fuselage to be stretched
without modifying the landing gear. The 707 fuselage could not
have been lengthened as much as the Douglas plane because of
limits due to tail strikes
(search)
during takeoff
rotation.
In April,
1965 a decision was made to offer combinations of both the
performance improvements and the stretched fuselage with a
family of three models tailored for domestic and international
routes. Thus was born the DC-8 Super 60 Series.
DC-8-61
- The first model of the series featured the same wing, fuel
capacity and JT3D-3B
(search)
power plant
installation as the DC-8-55. The maximum gross takeoff weight
remained at 325.000 lbs. The fuselage, however, was stretched 36
ft. 8 in. (240 inches forward of the wing, 200 inches aft). The
added cabin length permitted a maximum high-density seating of
259, up from 189 in the earlier standard body models. Cargo
holds grew from 1,390 cu ft to 2,500 cu ft allowing for
substantial revenue freight beyond the baggage space
requirements.
Range of the
-61 was adequate for the domestic needs of United, Delta,
Eastern, Air Canada, National, and JAL. The plane could carry
maximum payloads from New York to Los Angeles and between the
West Coast and Hawaii. Seventy eight of this model were
delivered.
First flight
was accomplished on March 14, 1966.
A
convertible passenger - cargo version, the DC-8-61CF, was
also offered. With its large main deck cargo door and
reinforced floor, ten of the CF planes were built and delivered
to Saturn, Trans Caribbean, TIA, and Universal. The longer
fuselage allowed for 17% more cubic cargo capacity than Series
50 freighters.
DC-8-62
- To compete more effectively in the long range market, Douglas
applied aerodynamic improvements - the 6 ft span increase, the
long duct engine pod, and cut back pylons - with a modest
fuselage stretch of 6 ft, 8 in (40 inch plugs fore and aft of
the wing). Static engine thrust went up to 19,000 lbs with the
JT3D-7 engine. Gross weight was raised to 350,000 lbs ( -62H)
and fuel capacity was increased to 24,275 gallons. First flight
of the -62 was on August 29, 1966.
The
increased performance of the -62 permitted scheduled service on
the polar route between the U.S. West Coast to Europe, Rome -
Buenos Aires, and transpacific flights. Fifty one passenger
planes were delivered. In addition, six all freighters and
eight convertible freighters were sold.
DC-8-63
- The last model of the family combined the stretched fuselage
of the -61 with the performance improvements of the -62. The
resulting aircraft was tailored for the major transatlantic
routes. After its maiden flight on April 10, 1967, 40 passenger
planes were delivered to KLM, SAS, Iberia, Air Canada, Canadian
Pacific, and VIASA.
Freighter
versions of the -63 included the -AF with a maximum payload of
114,700 lb. Seven -AFs were built for Flying Tiger. The -CF, of
which 53 were delivered, was the best selling version of all the
60 Series. Twelve customers, many of which were supplemental
carriers, bought this type. Eastern Airlines took six
specialized -63PF airplanes, combining the heavy cabin floors
and strengthened wing and landing gear of the freighters, but
without a main deck cargo door. These planes were acquired for
passenger duty, with an eye toward eventual conversion to
freighter work.
The Super
Sixty program produced sales of 262 airplanes, and might have
sold in even higher numbers except for Douglas’ problems in
getting the production line cranked up to meet the new greater
demand. Lengthened lead times for purchased items such as
forgings, and Vietnam war priorities for engines and other
components caused delays receiving materiel at Long Beach.,
This interrupted the efficient sequence of work and caused it to
be done out of planned production line positions. Another
costly problem was the company’s difficulty in recruiting
competent production workers. At the time, Lockheed, Northrop,
North American, General Dynamics, and many suppliers were
competing for skilled hands. As a result, the big investment in
the Super Sixty program produced nine versions of the long range
jet transport and a much improved market presence. And,
unfortunately, a hemorrhage of cash.
In 1967,
Douglas merged with McDonnell Aircraft. The new MDC strategy for
commercial airplanes led to moving on to wide-body markets and
the DC-10
(search)
. Further
improvement of the DC-8 would consist of supporting the General
Electric - Cammacorp DC-8 Series 70, a re-engining program using
the CFM56
(search)
high bypass ratio
turbofan.
Quoting from
Wikipedia, “Throughout its production life the DC-8 was
often regarded, unfairly, as little more than a copy of the 707,
which outsold it by roughly two to one. But in the longer term
the DC-8 proved its value. By 2002, of the 1,032 707s and 720s
manufactured for commercial use, just 80 remained in service —
though many of those 707s wound up converted for USAF use,
either in service or for spare parts. Of the 556 DC-8s made,
around 200 were still in commercial service in 2002, including
about 25 50-Series, 82 of the stretched 60-Series, and 96 out of
the 110 re-engined 70-Series. Most of the surviving DC-8s are
now used as freighters.”

Originally,
its USAF serial number was 61-999; in civilian use, it was

The Douglas Super DC-3/R4D-8

Photos
- The Boeing Company
Following
the end of WWII, the Douglas Company had to find new
opportunities for business while greatly downsizing its
operations. The natural market for the company was the
airlines. First priority became the development of large,
pressurized four-engine transports for the blue ribbon
transcontinental and transatlantic routes. Lockheed and Boeing
had seen this segment and were developing the
Constellation and
Stratocruiser.
Douglas opted for the DC-6.
Most
shorter airline routes were served by DC-3s. The huge supply of
military surplus
C-47s
at bargain prices made competing in this market sector risky. In
the late 1940s, questions arose with the CAA (search)
about the airworthiness of the DC-3/C-47 performance and it
appeared that the airlines might embrace a more capable,
modified Gooney Bird.
With large
financial exposure on the books, and the fact that
Martin and
Convair were
building pressurized twins, the Douglas Company looked for a
niche in the medium-range market involving low investment. In
1947 the Super DC-3 project was initiated with Mal Oleson
as project engineer.
It was
decided to modify existing airframes which could be acquired at
low cost from the ample surplus market instead of building new
planes from scratch. The company bought two second hand
aircraft - one C-47, the other an ex-DC-3 - and made them
prototypes of the new Super DC-3. Engines were upgraded
to 1,475 hp Wright R-1820, or 1,450 hp P&W R-2000s from typical
1,200 hp power plants in the DC-3/C-47. The fuselage was
lengthened 39 inches forward of the wing and 40 inches aft,
allowing thirty seats to be installed compared to 21 before
modification. To accommodate the new power and balance
characteristics, wing geometry was modified to use squared-off
tips as span was reduced by 5 ft. Tail surfaces were enlarged
and laid out with square tips as well and a larger dorsal fin
was fitted. The DC-3’s slow landing gear retraction time was
reduced as a result of a hydraulic system redesign, and doors
were added to the wheel wells. An airstair and retractable
tailwheel were adopted . Electrical system improvements were
made and new heating unit was installed in the fuselage below
the floor to solve a long time problem of passenger-cabin
heating.
With these
mutations in place, Douglas claimed that the DC-3S was a 75%
new airplane. In performance, cruise speed increased 21% from
207 mph to 251 mph, and improvements in engine-out situations
let the airplane meet the 1952 CAR standards. (Which were
eventually waived for DC-3s)
First
flight was made on June 23, 1949 with John Martin as pilot.
(This plane, N30000, served as the company transport for many
years.) Flight tests demonstrated better-than-predicted
performance.
Despite the
Douglas Company’s efforts to keep the cost down, the conversion
was not cheap. The price was between $250,000 and $300,000
(excluding the original price of the DC-3 airframe). As a
comparison, a Convair CV340 would seat 44 passengers, flew
faster and would cost about $570,000 brand new. As a result,
after a demonstration/sales tour, only three Super DC-3s were
ordered for airline use - all of them went to Capital Airlines
and they flew in scheduled service for only two years.
The Air
Force bought one of the prototypes from the company, designated
it the YC-129 (later changed to the YC-47F) for
evaluation. When the type was not selected by the USAF,
it was transferred to the Navy and renamed R4D-8.
In 1962 the military changed to designation again to C-117.
At last, a
customer was found for the Super Three. The Navy signed a
contract to modify 100 R4D-5s, R4D-6s and R4D-7s to the new
type, R4D-8.
The
airplane served U.S. Navy and Marine Corps in various roles
including staff transports and special missions including cold
weather operations for more than 20 years.
Many of the
R4D-8/C-117s found their way into the surplus market. As late as
1993, there were at least 19 still flying in the United States.
Others were in Canada. Philippines, and Latin America.

The Douglas DC-4 / C-54 / R5D
With
the rapid evolution of civil aviation in the mid-1930s and
building on the success of the
DC-3,
five airlines - American, Eastern, Pan American, TWA, and United
- each committed $100,000 to the Douglas Company for the
development of a prototype of a large, long range transport. In
1936 the specifications for the airplane were completed for the
DC-4.
The project was an ambitious one: provisions for 42 passengers,
a range of 2,200 miles, power-boosted controls, an auxiliary
power system, and air conditioning with provisions for a
pressurized cabin in the production models. The prototype made
its maiden flight on June 7, 1938 from
Clover
Field, and the next year was used for suitability
trials by United Air Lines. Although the airplane had good
flying qualities and was a big step forward in passenger
comfort, the DC-4 was ahead of its time: The complicated systems
caused unacceptable reliability. This, and the airplane’s high
operating costs, led TWA and Pan American to lose interest and
move to Boeing’s smaller
307
Stratoliner. Eastern, American and United asked Douglas
to simplify the design, leading the company to abandon the
existing configuration (which was renamed DC-4E - for
experimental), remove the complexity to better satisfy a
realistic airline environment, and start a new, simpler, more
reliable DC-4 development.
Santa
Monica engineering led by
Arthur Raymond
and E.F. Burton, redesigned the DC-4 to become a 25% lighter,
less complicated airplane. The tricycle landing gear
arrangement with a steerable nosewheel was retained, but the
power controls and air conditioning were dropped (the type was
offered with an optional pressurized cabin, but no DC-4 were
ever built with this feature.) The fuselage had a constant cross
section fore and aft of the wing which made the development of
stretched variants more practical. The post war
DC-6
and DC-7s
benefitted from this design principle.
Before the
new airliner made its maiden flight on Valentines Day 1942, the
United States had entered WWII and the production of the
aircraft was shifted to the
US Army Air Corps and given the model number,
C-54
and the name “Skymaster.” The designation
R5D was used for aircraft assigned to the Navy.
1,163
C-54/R5Ds were built for the United States military services
between 1942 and January 1946.
Douglas
continued to develop the type during the war in preparation for
a return to airline services when peace returned, but after
VJ Day just 79 DC-4s were built before production ceased on
August 9, 1947. New planes had to compete in the market with
some 500 C-54/R5Ds being offered as surplus by the US military.
C-54s and
R5Ds gave the military the vital capability of long range cargo
and passenger service to the far-flung theaters of operations in
the global WWII. The aircraft had an outstanding record of
safety and reliability: According to
René Francillon, in his chapter on the type, “during
the war Skymasters completed 79,642 transocean flights with only
three ditchings, of which one was a test.”
One
aircraft, a
VC-54 christened the "Sacred
Cow", was the first airplane assigned to carry the
president.. I was used to take
President Roosevelt to the summit meeting in
Yalta
in April, 1945.
C-54s were
operated by the Royal Air Force in the last year of the war, and
the French were supplied with one aircraft as a gift from the
USA for the use of
General
deGaulle after
VE
Day. When the airplane became widely available through
surplus sales, at least fifteen other nations acquired the type
for their armed services.
Many
airlines acquired surplus planes and converted them for
scheduled flights. DC-4s opened the North Atlantic route to
regular services by both US and European carriers.
Transpacific, South Atlantic, and Asian trunk services soon
followed. (All these blue ribbon routes became the first to be
served by the DC-6, Constellation, and Stratocruiser
pressurized, higher performance transports in just a couple of
years after the DC-4 pioneered them.)
In June,
1948, Soviet occupation forces closed surface roads and rail
access to Berlin in an attempt to deny any control of the
partitioned city to the US, UK, and France. The Allies
immediately began to supply the city by air. During the more
than 13 months of its existence, the
Berlin Airlift
saw 278,228 flights deliver 2,326,406 tons of cargo, including
1.5 million tons of coal to a city of high importance to both
east and west. Skymasters formed the backbone of the fleet. At
the peak of the operation 204 C-54s and 22 R5Ds were employed
along the air corridors leading to
Templehof from France and Belgium. The historic airlift
was so successful that the Soviets lifted the blockade in May
1949.

The Douglas F3D SkyNight
At
the end of WWII there was a convergence of new technologies -
jet propulsion, air-to-air guided missiles, and capable airborne
radars. And at the same time, there was the emerging
recognition of a new global threat to the United States - a
confrontation between the east and west.
Late in 1945, the Navy saw a need
for a carrier-capable night fighter and asked Grumman,
Fleetwings, and Douglas to propose designs to fill this
concept. The requirements were for a two-seat aircraft to be
able to identify a target flying at 40,000 ft at 500 mph at a
distance of 125 miles and then engage it with new guided
missiles. In April of 1946, the Navy ordered prototypes from
Grumman (XF9F-1) and from Douglas (XF3D-1). The Grumman
offering eventually evolved into the single-seat Panther day
fighter, while the
XF3D Skyknight
took on the role of the first jet night fighter able to operate
from the deck of an aircraft carrier. Design and development of
the XF3D was undertaken at the El Segundo Division, with Ed
Heinemann in the lead role.
On March 23 1948, with Russ Thaw
at the controls, the first XF3D-1 made its maiden flight from
Mines Field. That plane, along with two others, demonstrated
the suitability of the type in a test program at Edwards Air
Force Base during the fall of that year.
Douglas received its first order
for 28 F3D-1s for the Navy and Marine Corps. The first
production ship (BuNo 123741) flew on February 13. 1950, and the
type entered US Navy and Marine Corps service early in 1951.
Follow-on orders of the
Skyknight
program were for the F3D-2. Improvements for this
version included electronic system upgrades and an autopilot, a
more rugged windshield, and wing spoilers. The -2 was
scheduled to be fitted with Westinghouse J46 engines with 4,500
lbs of thrust, but that engine had technical problems so severe
that the 3,400-lb-thrust J34s, which powered the prototypes and
the initial production batch of the fighter, was retained for
the F3D-2 even through the planned performance upgrades were
sacrificed.
A swept wing version of the Skyknight,
the F3D-3, was planned. This version would have utilized
the J46, but with the discontinuation of the engine program,
there was insufficient performance improvement to justify the
production and an order for 287 -3s was cancelled.
In September 1962, the F3D-2 was
redesignated F-10B under the new Tri-Service unified designation
system. The F3D-2M (Sparrow missile-armed) became MF-10B, the
F3D-2Q (electronc countermeasure) became EF-10B, and the F3D-2T2
trainer became TF-10B.
The performance of the Skyknight
was never very impressive, and, following the end of the Korean
War, the F3Ds were rapidly replaced in Navy frontline service by
more advanced single-seat types such as the
F4D
Skyray. The Navy Skyknights were then relegated to training
and experimental roles.
A total of 268 of the Douglas
night fighters were built. The final ship was delivered on
March 23, 1952.
The Skyknight remained active
with the Marine Corps for somewhat longer than it did with the
Navy. By the time of Vietnam, EF-10Bs electronic countermeasures
aircraft were still serving with
VMCJ-1, -2, and -3. They flew tactical jamming and ferret
missions out of Da Nang with VMCJ-1 in support of strike
aircraft attacking targets in North Vietnam. The last Marine
Corps EF-10Bs were retired in May of 1970.

raised platform next to Woodruff, between Carson and Del Amo.

The Douglas TBD-1 Devastator
The
Douglas
TBD-1 was the Navy's first widely-used monoplane shipboard
plane. Designed to carry a heavy torpedo below the fuselage, it
was necessarily a large aircraft and its 900-horsepower
Pratt & Whitney R-1830 "Twin Wasp" radial engine could drive
it to a maximum speed of slightly over 200 miles per hour. The
XTBD-1 first flew in April 1935 and 129 production TBD-1s were
delivered in 1937-39, rapidly replacing biplanes in the Navy's
carrier torpedo squadrons. The type gave U.S. Fleet aviators
valuable experience with what was, for the time, a rather
high-performance aircraft. Operational attrition whittled away
at the TBD inventory, which peaked at about 120 in 1939 and had
declined to barely more than a hundred at the start of the
Pacific War.
Though the new
Grumman TBF "Avenger" was entering production as its
intended replacement, the TBD-1 was the Pacific Fleet's sole
torpedo plane for the first part of the war against Japan. It
seemingly did well in the raids of February-March 1942 and in
the
Battle of the Coral Sea in early May, serving in both the
torpedo attack and high-level bombing roles. However, in about
an hour's time on 4 June 1942, during the
Battle of Midway, the TBD entered the annals of Naval
history as a synonym for costly futility. Three squadrons of
TBD-1s, VT-5 from
Yorktown, VT-6 from
Enterprise, and VT-8 from
Hornet, made heroic torpedo attacks on the Japanese carrier
force. All but four of forty-one aircraft in the raid were lost
while achieving no hits. Old and slow, with a weak defensive
armament and without self-sealing fuel tanks, the TBD had proven
horribly vulnerable to enemy fighters, though this vulnerability
was to a great extent typical of all torpedo attacks against
well-defended ships.
At the end of the Midway battle, the Navy
had just thirty-nine TBDs left. New Avengers quickly took their
place on Pacific Fleet flight decks, but the older planes
continued to serve (briefly) in the Atlantic Fleet and in
training squadrons until late 1943. By this time, air torpedo
attacks were seldom used because of the vulnerability of even
the newest bombers. The twenty-one TBDs left in the Navy
inventory at the start of 1944 were mainly employed as
stationary hulks for maintenance training, and all were gone by
the end of that year. There are no surviving TBDs today, though
hope exists for recovery, restoration and exhibit of a plane
lost at sea.
The TBD's short production life, and
specialized intended employment, precluded much variety in the
type. The first production unit was converted to a floatplane,
designated TBD-1A, and used for tests well into World War II.
With the 1941 adoption of popular names for Navy aircraft, the
TBD began to be called the "Devastator", but for most of its
operational life, it was just known as the TBD-1.
