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.
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 ]
The engines were also changed from the Bristol Proteus turboprop engines to Wright R-3350 turbo-compound piston radial engines, which had lower fuel consumption necessary for extended missions at low level. [5] At the design stage the Napier Nomad, another turbo-compound engine, was also considered, although the Nomad was later cancelled.

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.
Slightly redesigned engine cowlings and new Curtiss Electric propellers were also introduced. Lockheed also offered an L-749 to L-749A conversion kit. The first civil customer for the L-749A was South African Airways but its largest customer was TWA, which had 26 L-749As; the last of these were not retired until 1967. A cargo version of the L ...
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 ...
Based on the design of the Lockheed L-049 (subsequently adopted by the United States Army Air Forces as the C-69), the L-249 never progressed past the design stage, mainly because Boeing had a head start with its Boeing B-29 Superfortress [citation needed], using the same Wright R-3350 Duplex-Cyclone radials as the XB-30 was intended to use ...
