Wright R-3350 Duplex-Cyclone Turbo-Compound radial engine.. The first aircraft engine to be tested with a power-recovery turbine was the Rolls-Royce Crecy.This was used primarily to drive a geared centrifugal supercharger, although it was also coupled to the crankshaft and gave an extra 15 to 35 percent fuel economy.
The original XB-33 design was to have been powered by the R-3350, the redesigned XB-33A was to have used Wright R-2600 engines. The main reason for this was the demand for R-3350s for the B-29, one of the most highly valued projects of the Army Air Forces.
The new design used the L-1049G fuselage, the new 150 ft (46 m) wing and four Wright R-3350 988 TC18-EA-2 turbocompound radial engines, allowing the Starliner to fly nonstop from California to Europe.
During the 1940s, Wright Aeronautical Corporation was constantly in competition with Pratt & Whitney for new engine designs required for civil and military aircraft. . Utilizing the Wright R-3350 Duplex-Cyclone as a basis, Wright developed a 22-cylinder engine, using R-3350 cylinders arranged as a two-row radial engine with 11 cylinders per row inst
The ASh-73 was not a reverse-engineered copy of the Wright R-3350 Duplex-Cyclone, itself starting its development in 1937: "There was no need to copy the Wright R-3350-23A; the engine that was put into production was the indigenous ASh-73TK - a further development of the M-71 and M-72, which differed in being fitted with twin TK-19 ...
When Curtiss-Wright offered an improved version of the Wright R-3350 Duplex-Cyclone, Lockheed began developing an improved version of the L-049 Constellation airliner to be powered by this engine. The new project was designated L-049-84. In addition to the engine change, the wing and fuselage structure were strengthened to allow an increased ...
