The Wright R-3350 Duplex-Cyclone is an American twin-row, supercharged, air-cooled, radial aircraft engine with 18 cylinders displacing nearly 3,350 cubic inches (54.9 L). Power ranged from 2,200 to 3,700 hp (1,640 to 2,760 kW), depending on model. Developed before World War II, the R-3350's design required a long time to mature, and was still ...
The Wright R-3350 was a twin-row, 18-cylinder radial engine that was developed from the Wright R-1820 Cyclone and was one of the most powerful radial engines produced in the United States. Work on the engine began in January 1936 and the first R-3350 was run in May 1937.
Wright Cyclone was the name given to a family of air-cooled radial piston engines designed by the Wright Aeronautical Corporation and used in numerous American aircraft in the 1930s, 1940s and 1950s.
The huge Wright R-3350 Duplex Cyclone was an air-cooled, 2,200-horsepower, twin-row, eighteen-cylinder engine. With a displacement of 3,350 cubic inches, it was one of the most powerful radial aircraft engines produced by the United States.
A former engine to Lockheed Constellation 5T-TAF c/n 4618, it was one of two engines recovered for restoration. Basic engine details: 18 cylinder radial in two banks of 9.
Radial engines employing the master/articulating rod system exhibit a secondary unbalance due to the different motion of each piston. In single row engines, this tends to whirl the engine in a circle eccentric to the crankshaft. This tendency becomes worse as the number of cylinders per row increases. Two-row
The Wright R-3350 Duplex-Cyclone was one of the most powerful radial aircraft engines produced by the United States. Based on the earlier Wright Cyclone engines, the R-3350 first ran in May 1937, and its first major military use was to power the Boeing B-29.
The R-3350 is a twin row, supercharged, air-cooled, radial engine with 18 cylinders and a displacement of 3,350 cubic inches. Horsepower ranges from 2,200 to over 2,800, depending on the model. Click here to return to the Featured Accessions index.
Wright Turbo-Cyclone 18R-3350-TC Radial Engine. This engine powered the last generation of piston engine transports, including the Douglas DC-7 and Lockheed Super Constellation.
These radial engines with two rows of nine cylinders on offer and sharing a common prop-shaft measured in a massive 3,350 cubic inches (54.9 L). In general, radial, or reciprocating engines,...
