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.
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.
Later that year the US Navy awarded Wright a contract to develop two new air-cooled radial engines. The first, called the P-1, was a 9-cylinder single row design of 1,652 cu in (27.07 L) displacement that was derived from an earlier Lawrence design, it produced 400 hp (300 kW). [ 2 ]

Modification with two 3,250 pounds-force (14.5 kN) J34 jet engines to increase power on take-off, and 3,500 horsepower (2,600 kW) R-3350-32W piston engines. [43] The J34 engines and R-3350 had a common fuel system burning AvGas rather than having dedicated jet fuel (as did all Neptunes with jets except the Kawasaki P-2J).
In 1945 three C-46As were fitted with Wright R-3350 radial piston engines. Curtiss C-46R/Super 46C post-war modified C-46D of LANSA Honduras in 1978 XC-113 Engine change: One C-46G, s/n 44-78945, was converted into an engine testbed, the aircraft was fitted with a General Electric T31 turboprop in place of right-hand side R-2800. The aircraft ...
Single-tail design, and having a longer hull with fewer bulkheads and a larger maximum take-off weight. It had also been fitted with equipment for overhead cargo handling and was powered by four Wright R-3350-24WA Cyclone engines with 4-bladed propellers, five built, surviving four converted to JRM-3. JRM-2
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 instead of 9. [ 1 ] The air-cooled R-4090 was rated to deliver 3,000 hp (2,200 kW) at 2,800 rpm for take-off, from a total displacement of 4,092 cu in (67.06 L), with ...
