The rival Saito Seisakusho firm in Japan has since produced a similarly sized five-cylinder radial four-stroke model engine of their own as a direct rival to the OS design, with Saito also creating a series of three-cylinder methanol and gasoline-fueled model radial engines ranging from 0.90 cu.in. (15 cm 3) to 4.50 cu.in. (75 cm 3) in ...
One example was a 3.1 litre (186 cu in) unit producing 22 kW (30 hp) at 1,300 rpm. [5] Although termed the Y engine after its symmetric cylinder arrangement, it ran in an inverted Y position so that the plugs, mounted on the upper in-plane side of the two lower cylinders were less than 30° below the horizontal and less prone to oiling than one ...
The Continental R-670 (factory designation W670) was a seven-cylinder four-stroke radial aircraft engine produced by Continental displacing 668 cubic inches (11 litres) and a dry weight of 465 lb (211 kg). Horsepower varied from 210 to 240 at 2,200 rpm. The engine was the successor to Continental's first radial engine, the 170 hp Continental A ...
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 ...
For example: the -18W was a "C" series engine, built from 1945, whereas the -21 was a "B" series engine, built from 1943. Until 1940 the armed forces adhered strictly to the convention that engines built for the Army Air Forces used engine model numbers with odd numeric suffixes (e.g.: -5), while those built for the US Navy used even (e.g.: -8).
LeBlond 40-3 3-cylinder air-cooled radial engine. [2] LeBlond 60-5D Introduced in 1928, [3] the 60-5D was a 60 hp (45 kw) 5-cylinder, air-cooled, radial piston engine with a displacement of 234 cuin (3.8 L). [4] This model used iron cylinder heads [5] and was a direct development of the Detroit Air-Cat. [3] [2] LeBlond 70-5DE
Grumman was not happy with the performance, which led to the 2,000 hp Pratt & Whitney R-2800 engine replacing the R-2600 on F6F production models. [7] R-2600-15 - 1,800 hp (1,342 kW)- Planned to power the XB-33A, a prototype model of the B-33 Super Marauder (itself a high-altitude version of the B-26 Marauder). The project was cancelled, and ...
The Nakajima Sakae (栄, Glory) was a two-row, 14-cylinder air-cooled radial engine used in a number of combat aircraft of the Imperial Japanese Navy and Imperial Japanese Army before and during World War II.
