The Taurus is a British 14-cylinder two-row radial aircraft engine, produced by the Bristol Engine Company starting in 1936. The Taurus was developed by adding cylinders to the existing single-row Aquila design and transforming it into a twin-row radial engine, creating a powerplant that produced just over 1,000 horsepower with very low weight.
The Nakajima Sakae 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.
The Piaggio P.XI was an Italian 14-cylinder radial aircraft engine. The P.XI was a licensed derivative of the French Gnome-Rhône Mistral Major 14K produced in Italy.
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 Mitsubishi Kinsei was a 14-cylinder, air-cooled, twin-row radial aircraft engine developed by Mitsubishi Heavy Industries in Japan in 1934 for the Imperial Japanese Navy. The Mitsubishi model designation for this engine was A8 while it was an experimental project; in service, it was known as the MK8 "Kinsei" by the Navy. In 1941 the engine was adopted by Army, receiving designation Ha-112. In May 1943 it received Ha-33 unified designation code.
The Walter Venus was a seven-cylinder, air-cooled, radial engine for aircraft use, built in Czechoslovakia in the late 1920s.
The Gnome-Rhône 14N was a 14-cylinder two-row air-cooled radial engine designed and manufactured by Gnome-Rhône just before the start of World War II. A development of the Gnome-Rhône 14K, the 14N was used on several French and even one German aircraft.
The Fiat A.74 was a two-row, fourteen-cylinder, air-cooled radial engine produced in Italy in the 1930s as a powerplant for aircraft. It was used in some of Italy's most important aircraft of World War II.
The Gnome et Rhône 18L was a French-designed twin-row 18-cylinder air-cooled radial engine. The 18L was a large step up in terms of displacement, power and number of cylinders. The majority of Gnome-Rhone engines were either 7, 9 or 14 cylinders. The engine proved not to be a success, and it was dropped in 1939 due to a poor power-to-weight ratio.
The Bristol Titan was a British five-cylinder air-cooled radial engine, designed and built by the Bristol Aeroplane Company in the late 1920s. It had the same size cylinders as the earlier Bristol Mercury engine, 5.75 in × 6.5 in, and produced between 200–240 hp (150–180 kW). Later versions of the Bristol Titan also used a Farman-style reduction gear produced by Gnome-Rhône.
The Gnome-Rhône 7K Titan Major was a seven-cylinder 370 hp (270 kW) air-cooled radial engine, that started life as an enlarged Gnome-Rhône 5K with two extra cylinders.
The Gnome-Rhône 9K Mistral was a nine-cylinder 550 hp (405 kW) to 700 hp air-cooled radial engine, that started life as an enlarged Gnome-Rhône 7K with two extra cylinders.
The Tumansky M-88 was an air-cooled radial engine for aircraft developed in the Soviet Union shortly before World War II.
The Alfa Romeo 135 Tornado was an Italian 18-cylinder radial engine designed by Giustino Cattaneo in 1934–1935.
The Bristol Neptune was a seven-cylinder air-cooled radial engine developed in 1930. It had the same size cylinders as the earlier Mercury and Titan engines, 5.75 in (146 mm) x 6.5 in (165 mm) which gave a displacement of 1,182 cu in and produced a maximum of 320 horsepower (239 kW). The Neptune was effectively a seven-cylinder version of the Titan.
The IAR K14 was a Romanian 14-cylinder radial aircraft engine. The IAR K14 was a licensed derivative of the French Gnome-Rhône 14K Mistral Major produced in Romania.
The Piaggio P.XII is an Italian 18-cylinder radial aircraft engine developed in the 1930s by Rinaldo Piaggio S.p.A. The P.XII was two Piaggio P.X engines in tandem, which were versions of the French Gnome-Rhône 9K Mistral made under license, themselves being much modified Gnome-Rhône 9A - a license-built Bristol Jupiter.
The Piaggio Stella P.VII was the first P series aircraft engine produced by Rinaldo Piaggio S.p.A. Based on its experience license-producing the Gnome-Rhône 7K, Piaggio sold the engine to be used on a wide range of Italian aircraft before and during World War II, including the record-breaking Caproni Ca.133.
The Piaggio P.IX, or Piaggio Stella P.IX, was an Italian nine-cylinder radial aircraft engine produced by Rinaldo Piaggio S.p.A. Based on the Gnome-Rhône 9K, the engine was rated at 600 hp (447 kW). Production was used to power a number of other aircraft developed in Italy. The main users were the Savoia-Marchetti SM.81 transport and the IMAM Ro.37bis, the main reconnaissance aircraft in the Regia Aeronautica during the Second Italo-Ethiopian War, Spanish Civil War and Second World War, but the engine was also used by other designs, including the prototype Savoia-Marchetti SM.79.
The Piaggio P.X, or Piaggio Stella P.X, was an Italian nine-cylinder radial aircraft engine produced by Rinaldo Piaggio S.p.A. Based on experience license-producing Gnome et Rhône designs, the engine was used to power a number of aircraft during World War II, including the IMAM Ro.37bis and IMAM Ro.43, used extensively by the Regia Aeronautica and Regia Marina respectively.
