DC-4
The Douglas DC-4 is an American four-engined (piston), propeller-driven airliner developed by the Douglas Aircraft Company. Military versions of the plane, the C-54 and R5D, served during World War II, in the Berlin Airlift and into the 1960s. From 1945, many civil airlines operated the DC-4 worldwide. Design and development Following proving flights by United Airlines of the DC-4E, it became obvious that the 52-seat airliner was too inefficient and unreliable to operate economically and the partner airlines, American Airlines, Eastern, Pan American, Trans World and United, recommended a lengthy list of changes to the design. Douglas took the new requirements and produced an entirely new, much smaller design, the DC-4A, with a simpler, still unpressurized fuselage, Pratt & Whitney R-2000 Twin Wasp engines, and a single fin and rudder. A tricycle landing gear was retained. With the entry of the United States into World War II, in December 1941, the United States Army Air Forc ...

Douglas DC-4E
The Douglas DC-4E was an American experimental airliner that was developed before World War II. The DC-4E never entered production due to being superseded by an entirely new design, the Douglas DC-4/C-54, which proved very successful. Many of the aircraft's innovative design features found their way into the Nakajima G5N bomber after the single DC-4E prototype was sold to a Japanese airline and clandestinely dismantled for study by Nakajima at the behest of the Imperial Japanese Navy. Design and development The design originated in 1935 from a requirement by United Air Lines. The goal was to develop a much larger and more sophisticated replacement for the DC-3 before the first DC-3 had even flown. Such was the initial interest from other airlines, that American Airlines, Eastern Air Lines, Pan American Airways and Transcontinental and Western Air (TWA) joined United, providing $100,000 each toward the cost of developing the new aircraft. As cost and complexity rose, Pan Amer ...

Canadair North Star
The Canadair North Star is a 1940s Canadian development, for Trans-Canada Air Lines (TCA), of the Douglas DC-4. Instead of radial piston engines used by the Douglas design, Canadair used Rolls-Royce Merlin V12 engines to achieve a higher cruising speed of compared with the of the standard DC-4. Requested by TCA in 1944, the prototype flew on 15 July 1946. The type was used by various airlines and by the Royal Canadian Air Force (RCAF). It proved to be reliable but noisy when in service through the 1950s and into the 1960s. Some examples continued to fly into the 1970s, converted to cargo aircraft. Design and development Canadair Aircraft Ltd. took over the Canadian Vickers Ltd. operations on 11 November 1944. Besides the existing Consolidated PBY Canso flying patrol boats in production, a development contract to produce a new variant of the Douglas DC-4 transport was still in effect. The new Canadair DC-4M powered by Rolls-Royce Merlin engines mounted in Rolls-Royce Universa ...

Aviation Traders Carvair
The Aviation Traders ATL-98 Carvair is a retired large transport aircraft powered by four radial engines. It was a Douglas DC-4-based air ferry conversion developed by Freddie Laker's Aviation Traders (Engineering) Limited (ATL), with a capacity generally of 22 passengers in a rear cabin, and five cars loaded in at the front. Design and development Freddie Laker's idea to convert surplus examples of the Douglas DC-4 and its military counterpart the C-54 Skymaster to carry cars was a relatively inexpensive solution to develop a successor to the rapidly aging and increasingly inadequate Bristol 170 Freighter, the car ferry airlines' mainstay since the late 1940s. The Bristol Freighter's main drawback was its limited payload, in terms of the number of cars that fitted into a single aircraft. Even the "long-nosed" Mark 32 was able to accommodate only three cars (in addition to 20 passengers). This made carrying cars by air a very tricky business. If a booked car failed to turn up, ...

C-54 Skymaster
The Douglas C-54 Skymaster is a four-engined transport aircraft used by the United States Army Air Forces in World War II and the Korean War. Like the Douglas C-47 Skytrain derived from the DC-3, the C-54 Skymaster was derived from a civilian airliner, the Douglas DC-4. Besides transport of cargo, the C-54 also carried presidents, prime ministers, and military staff. Dozens of variants of the C-54 were employed in a wide variety of non-combat roles such as air-sea rescue, scientific and military research, and missile tracking and recovery. During the Berlin Airlift it hauled coal and food supplies to West Berlin. After the Korean War it continued to be used for military and civilian uses by more than 30 countries. It was one of the first aircraft to carry the President of the United States, the first being President Franklin D. Roosevelt during World War II. Design and development With the looming entry of the United States into World War II, in June 1941 the War Department t ...

Douglas DC-6
The Douglas DC-6 is a piston-powered airliner and cargo aircraft built by the Douglas Aircraft Company from 1946 to 1958. Originally intended as a military transport near the end of World War II, it was reworked after the war to compete with the Lockheed Constellation in the long-range commercial transport market. More than 700 were built and many still fly in cargo, military, and wildfire control roles. The DC-6 was known as the C-118 Liftmaster in United States Air Force service and as the R6D in United States Navy service prior to 1962, after which all U.S. Navy variants were also designated as the C-118. Design and development The United States Army Air Forces commissioned the DC-6 project as the XC-112 in 1944. The Army Air Forces wanted a lengthened, pressurized version of the DC-4-based C-54 Skymaster transport with more powerful engines. By the time the prototype XC-112A flew on 15 February 1946, the war was over, the USAAF had rescinded its requirement, and the aircra ...

Airliner
An airliner is a type of aircraft for transporting passengers and air cargo. Such aircraft are most often operated by airlines. Although the definition of an airliner can vary from country to country, an airliner is typically defined as an airplane intended for carrying multiple passengers or cargo in commercial service. The largest of them are wide-body jets which are also called twin-aisle because they generally have two separate aisles running from the front to the back of the passenger cabin. These are usually used for long-haul flights between airline hubs and major cities. A smaller, more common class of airliners is the narrow-body or single-aisle. These are generally used for short to medium-distance flights with fewer passengers than their wide-body counterparts. Regional airliners typically seat fewer than 100 passengers and may be powered by turbofans or turboprops. These airliners are the non- mainline counterparts to the larger aircraft operated by the major car ...

Douglas Aircraft Company
The Douglas Aircraft Company was an American aerospace manufacturer based in Southern California. It was founded in 1921 by Donald Wills Douglas Sr. and later merged with McDonnell Aircraft in 1967 to form McDonnell Douglas; it then operated as a division of McDonnell Douglas. McDonnell Douglas later merged with Boeing in 1997. History 1920s The company was founded as the Douglas Company by Donald Wills Douglas Sr. on July 22, 1921 in Santa Monica, California, following dissolution of the Davis-Douglas Company. An early claim to fame was the first circumnavigation of the world by air in Douglas airplanes in 1924. In 1923, the U.S. Army Air Service was interested in carrying out a mission to circumnavigate the Earth for the first time by aircraft, a program called "World Flight". Donald Douglas proposed a modified Douglas DT to meet the Army's needs. The two-place, open cockpit DT biplane torpedo bomber had previously been produced for the U.S. Navy.Rumerman, Judy.

Pratt & Whitney R-2000 Twin Wasp
The Pratt & Whitney R-2000 Twin Wasp is an American radial engine developed in 1942 to power military aircraft. It is one of the Pratt & Whitney Wasp series of Radial engines. Design and development The R-2000 was an enlarged version of the Pratt & Whitney R-1830 Twin Wasp, with focus on reducing the manufacturing costs and fuel requirements. The bore was increased to , while it still retained the stroke. This brought displacement up to . There were a number of detail changes from the R-1830, such as front-mounted instead of rear-mounted magnetos (as with the larger, and earlier Double Wasp), plain bearings for the crankshaft rather than roller bearings, and 87 octane fuel (specified because there were fears wartime supplies of 100 octane might fall short, but those fears were groundless). The R-2000 produced 1,300 hp @ 2,700 rpm with 87 octane, 1,350 hp with 100 octane and 1,450 hp @ 2,800 rpm with 100/130-grade fuel. Applications * Aviation Trader ...
