The Wright R-1820 Cyclone 9 was an American radial engine developed by Curtiss-Wright, widely used on aircraft in the 1930s through 1950s.
 It was produced under license in Spain as the Hispano-Suiza 9V or Hispano-Wright 9V, and in the Soviet Union as the Shvetsov M-25.
The SNECMA 14R was a 14-cylinder two-row air-cooled radial engine developed in France just prior to the start of World War II from the Gnome-Rhône 14N.
 The 14N radial engine was itself an improved version of the popular pre-war Gnome-Rhône 14K "Mistral Major" series; designed and manufactured by Gnome et Rhône, a major French aircraft engine manufacturer whose origins pre-date the First World War.
The Pratt & Whitney R-1830 Twin Wasp was an American aircraft engine widely used in the 1930s and 1940s.
 Produced by Pratt & Whitney, it was a two-row, 14-cylinder, air-cooled radial design.
 It displaced 1830 cuin and its bore and stroke were both 5.5 in (140 mm).
 A total of 173,618 R-1830 engines were built, and from their use in two of the most-produced aircraft ever built, the four-engined B-24 heavy bomber and twin-engined DC-3 transport, more Twin Wasps may have been built than any other aviation piston engine in history.
 A "bored-out" version (to a 5.75 inch/146 mm cylinder bore) with a slightly higher power rating and other slight changes in detail design was produced as the R-2000.
The Shvetsov ASh-2 was a 28-cylinder, air-cooled, radial aircraft engine designed in the Soviet Union in the late 1940s.
 It was inferior to the Dobrynin VD-4K engine and did not enter production.
 One of the problems was air-cooling which ate up to 50% of the total engine power at 15000 meters.
 In contrast, liquid-cooled VD-4K required only 5% of power for cooling at the same altitude.
The Shvetsov M-11 is a five-cylinder air-cooled radial aircraft engine produced in the Soviet Union between 1923 and 1952.
The Gnome-Rhône 14K "Mistral Major" was a 14-cylinder, two-row, air-cooled radial engine.
 It was Gnome-Rhône's major aircraft engine prior to World War II, and matured into a highly sought-after design that would see licensed production throughout Europe and Japan.
 Thousands of Mistral Major engines were produced, used on a wide variety of aircraft.
The Shvetsov ASh-62 (Russian: АШ-62, designated M-62 before 1941) is a nine-cylinder, air-cooled, radial aircraft engine produced in the Soviet Union.
 A version of this engine is produced in Poland as the ASz-62 and the People's Republic of China as the HS-5.
The Shvetsov ASh-82 (M-82) is a Soviet 14-cylinder, two-row, air-cooled radial aircraft engine developed from the Shvetsov M-62.
 The M-62 was the result of development of the M-25, which was a licensed version of the Wright R-1820 Cyclone.
Arkadiy Dmitrievich Shvetsov (Russian: Аркадий Дмитриевич Швецов ) (January 25, 1892, Nizhniye Sergi, today's Sverdlovsk Oblast - March 19, 1953, Moscow) was a Soviet aircraft engine designer whose OKB was founded in Perm, USSR, in 1934, to produce the Wright Cyclone-derived Shvetsov M-25 engine.
 Under Shvetsov, his OKB became the primary provider of radial piston engines for Soviet aircraft industry (Mikulin's and Klimov's OKB were assigned to creation of in-line engines).
 After his death in 1953, the OKB was taken over by Pavel Soloviev.
The Nakajima Ha-5 is a twin row, 14 cylinder air-cooled radial aircraft engine built by the Japanese Nakajima Aircraft Company.
 The engine was a development of earlier single-row Japanese engines, the Kotobuki and Hikari, which had combined features of the Bristol Jupiter and Pratt & Whitney R-1340 Wasp designs.
 First introduced in a 1,000 PS prototype in 1933, about 7,000 civilian and 5,500 military Ha-5's were built during World War II.
 The Ha-5 had separate cam-discs for the front and rear rows of cylinders like American designs, rather than using a single, front-mounted cam-disc with long and short pushrods to operate both rows of cylinder valves.
 The Ha-5 was a twin-row development of the Nakajima Hikari, which was itself a development of the Nakajima Kotobuki.
 It spawned several improved variants, namely the Ha-41, with a single stage supercharger, and the Ha-109, which featured a two-speed, single stage supercharger.
 The later Ha-219 was based on the same cylinder design, but was increased in size to 18 cylinders.
