DST with 1,000–1,200 hp (750–890 kW) Pratt & Whitney R-1830 Twin Wasp radial piston engines DC-3 Main prewar production variant fitted with 21 passenger seats, two 1,000–1,200 hp (750–890 kW) Wright R-1820 Cyclone engines DC-3A Improved DC-3 with two 1,000–1,200 hp (750–890 kW) Pratt & Whitney R-1830 Twin Wasp radial piston engines.
Several radial engines were offered for the DC-3. Early-production civilian aircraft used either the 9-cylinder Wright R-1820 Cyclone 9 or the 14-cylinder Pratt & Whitney R-1830 Twin Wasp , but the Twin Wasp was chosen for most military versions and was also used by most DC-3s converted from military service.
The Wright R-1820 Cyclone 9 is an American radial engine developed by Curtiss-Wright, widely used on aircraft in the 1930s through 1950s. It was produced under license in France as the Hispano-Suiza 9V or Hispano-Wright 9V , and in the Soviet Union as the Shvetsov M-25 .
The primary user of the R-2000 was the Douglas DC-4. Mostly retired today, the R-1830 is still used on Douglas DC-3 and various museum aircraft and warbirds seen at airshows. It is not manufactured anymore, but spares are still available and there is still a market for second-hand engines and parts.
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 engine mounted on the nose could be shut off, decreasing the speed to 180 mph (160 kn; 290 km/h) and increasing the range of the aircraft. It was used by Polair and Maritime Patrol and Rescue . [ citation needed ] It was fitted with skis for use in polar regions and flew in the North Pole region out of Resolute Bay Airport in Canada.
It was then the only airworthy Li-2 known. 2002-2008 named Kármán Tódor [4] Shvetsov ASh-62 radial piston engine, mounted on Li-2 HA-LIX, 2008 Li-2 HA-LIX Cockpit, 2008. The Lisunov Li-2 (NATO reporting name: Cab), originally designated PS-84, was a license-built Soviet-version of the Douglas DC-3.
This brought displacement up to 2,000 in 3 (32.8 L). There were a number of detail changes from the R-1830, such as front-mounted instead of rear-mounted magnetos (as with the larger, and earlier Double Wasp ), plain bearings for the crankshaft rather than roller bearings, and 87 octane fuel (specified because there were fears wartime supplies ...
