Wright R-3350 Duplex-Cyclone
The Wright R-3350 Duplex-Cyclone is an American twin-row, supercharged, air-cooled, radial aircraft engine with 18 cylinders displacing nearly . Power ranged from , depending on model. Developed before World War II, the R-3350's design required a long time to mature, and was still experiencing problems with reliability when used to power the Boeing B-29 Superfortress. After the war, the engine had matured sufficiently to be used in many civilian airliners, notably in its turbo-compound forms, and was used in the Lockheed L-1049 Super Constellation airliners into the 1950s. Its main rival was the , Pratt & Whitney R-4360 Wasp Major, which first ran some seven years after the Duplex-Cyclone. The engine is commonly used on Hawker Sea Fury and Grumman F8F Bearcat Unlimited Class Racers at the Reno Air Races. Design and development In 1927, Wright Aeronautical introduced its "Cyclone" engine, which powered a number of designs in the 1930s. After merging with Curtiss to become ...

Lockheed L-1049 Super Constellation
The Lockheed L-1049 Super Constellation is an American aircraft, a member of the Lockheed Constellation aircraft line. The aircraft was colloquially referred to as the Super Connie. The L-1049 was Lockheed's response to the successful Douglas DC-6 airliner, first flying in 1950. The aircraft was produced for both the United States Navy as the WV / R7V and U.S. Air Force as the C-121 for transport, electronics, and airborne early warning and control aircraft. Development Beginning in 1943, Lockheed planned stretched variants of the Constellation family. The first was the L-049 with a fuselage lengthened by and the second the L-749 stretched . Douglas launched a stretched version of its DC-6 airliner as a cargo transport, designated DC-6A, for both military and civilian operators. Douglas was soon to launch a passenger version (the DC-6B) of this new aircraft. The DC-6B could carry 23 more passengers than Lockheed's current production L-749 Constellation. In 1950, Lockhee ...

Wright R-2600 Twin Cyclone
The Wright R-2600 Cyclone 14 (also called Twin Cyclone) is an American radial engine developed by Curtiss-Wright, and widely used in aircraft in the 1930s and 1940s. History In 1935, Curtiss-Wright began work on a more powerful version of their successful R-1820 Cyclone 9. The result was the R-2600 Twin Cyclone, with 14 cylinders arranged in two rows. The R-2600-3 was originally intended for the C-46 Commando (being fitted to the prototype CW-20A). It was also the original engine choice for the F6F Hellcat; a running change (one which would not stop production) for the CW-20A, and one in late April 1942 for the second XF6F-1, led to the adoption of the Pratt & Whitney R-2800 Double Wasp in the R-2600's place for both designs. The Twin Cyclone went on to power several important American World War II aircraft, including the A-20 Havoc, B-25 Mitchell, TBF Avenger, SB2C Helldiver, and the PBM Mariner. Over 50,000 R-2600s were built at plants in Paterson, New Jersey, and Cinci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
R-1830 Twin Wasp
The Pratt & Whitney R-1830 Twin Wasp is an American air-cooled radial aircraft engine. It has 14 cylinders, arranged in two rings of seven. It displaces and its bore and stroke are both . The design traces its history to 1929 experiments at Pratt & Whitney on twin-row designs. Production began in 1932 and it was widely used during the 1930s. It was selected as the power plant for both the four-engined Consolidated B-24 Liberator heavy bomber and the twin-engined Douglas DC-3 transport, two of the most-produced aircraft. The production run of 173,618 R-1830 examples makes it the most-produced aviation engine in history. A further developed version, the R-2000, was produced starting in 1942. The R-2000 was "bored-out" to and had a number of other minor changes to improve fuel economy and allow it to run at higher power ratings on lower-octane fuel. The primary user of the R-2000 was the Douglas DC-4. Mostly retired today, the R-1830 is still used on Douglas DC-3 and va ...

Pratt & Whitney Wasp
The Pratt & Whitney Wasp was the civilian name of a family of air-cooled, radial piston engines developed in the 1920s, 1930s, and 1940s. The Pratt & Whitney Aircraft Company (P&W) was founded in 1925 by Frederick B. Rentschler, who had previously been the president of Wright Aeronautical. He brought with him some of Wright's best designers, and the new team quickly came up with their first design, the R-1340 Wasp.

General Motors FM-2 Wildcat
The Grumman F4F Wildcat is an American carrier-based fighter aircraft that entered service in 1940 with the United States Navy, and the British Royal Navy where it was initially known as the Martlet. First used by the British in the North Atlantic, the Wildcat was the only effective fighter available to the United States Navy and Marine Corps in the Pacific Theater during the early part of the Second World War. The disappointing Brewster Buffalo was withdrawn in favor of the Wildcat and replaced as aircraft became available. With a top speed of , the Wildcat was outperformed by the faster [], more maneuverable, and longer-ranged Mitsubishi A6M Zero. US Navy pilots, including John Thach, John "Jimmy" Thach, a pioneer of fighter tactics to deal with the A6M Zero, were greatly dissatisfied with the Wildcat's inferior performance against the Zero in the battles of the Coral Sea and Midway.
