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 ...
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).
The R-5 was a development of the earlier Kinner B-5, with slightly greater power and dimensions.The main change was the increase in cylinder bore from 117 mm (4.625 in) to 127 mm (5 in) and an increase in piston stroke from 133.3 mm (5.25 in) to 139.7 mm (5.5 in).
The Pratt & Whitney R-4360 Wasp Major is an American 28-cylinder four-row radial piston aircraft engine designed and built during World War II.At 4,362.5 cu in (71.5 L), it is the largest-displacement aviation piston engine to be mass-produced in the United States, and at 4,300 hp (3,200 kW) the most powerful.
Producing 360 hp (268 kW), its design dates from the 1940s (Kotelnikov 2005), and is itself a development of the Ivchenko AI-14 engine. The engine has been used extensively by the Yakovlev and Sukhoi Design Bureaus. The M14P is also used in some experimental aircraft and kit designs such as the Murphy Moose, Radial Rocket, Pitts Model 12, and ...

Anzani "Y" radial engine. Anzani was aware of the weight cost of the counterweight in the fan configuration and by December 1909 he had a symmetric 120° three-cylinder radial engine running. One example was a 3.1 litre (186 cu in) unit producing 22 kW (30 hp) at 1,300 rpm. [5]
Performance was similar to the equivalent Wright engines. The M-25 was later developed into the ASh-62 and was later used as a pattern for the M-70. The M-70, a twin-row 18-cylinder engine, eventually developed into the ASh-73 which powered the Tupolev Tu-4 , an unlicensed, reverse-engineered copy of the Boeing B-29 Superfortress .
