The Pratt & Whitney R-4360 Wasp Major is an American 28-cylinder four-row radial piston aircraft engine designed and built during World War II.At 4,362.5 cu in (71.5 L), it is the largest-displacement aviation piston engine to be mass-produced in the United States, and at 4,300 hp (3,200 kW) the most powerful.
The Pratt & Whitney Wasp was the civilian name of a family of air-cooled radial piston engines developed in the 1920s, 1930s and 1940s. [1] 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 ...
Pratt & Whitney now markets its Ecopower pressure-washing service, which uses a high-pressure water spray run through several nozzles to clean grime and contaminants from jet engine parts, most notably turbine blades, to prevent overheating, improve engine operating efficiency and reduce fuel burn. The system collects the runoff from the ...
Mechanics nicknamed them Parts Recovery Turbines, since the increased exhaust heat meant a return to the engine destroying exhaust valves. The fuel burn for the PRT-equipped aircraft was nearly the same as the older Pratt and Whitney R-2800, while producing more useful power. [5] Effective 15 October 1957 a DA-3/DA-4 engine cost $88,200. [6]
The Pratt & Whitney R-2800 Double Wasp is an American twin-row, 18-cylinder, air-cooled radial aircraft engine with a displacement of 2,800 cu in (46 L), and is part of the long-lived Wasp family of engines. The R-2800 saw widespread use in many important American aircraft during and after World War II.
The Pratt & Whitney R-985 Wasp Junior is a series of nine-cylinder, air-cooled, radial aircraft engines built by the Pratt & Whitney Aircraft Company from the 1930s to the 1950s. These engines have a displacement of 985 in 3 (16 L); initial versions produced 300 hp (220 kW), while the most widely used versions produce 450 hp (340 kW).
The Pratt & Whitney R-1830 Twin Wasp is an American air-cooled radial aircraft engine. It displaces 1,830 cu in (30.0 L) and its bore and stroke are both 5.5 in (140 mm). 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.
