The Bristol Pegasus is a British nine-cylinder, single-row, air-cooled radial aero engine. Designed by Roy Fedden of the Bristol Aeroplane Company, it was used to power both civil and military aircraft of the 1930s and 1940s. Developed from the earlier Mercury and Jupiter engines, later variants could produce 1,000 horsepower from its capacity of 1,750 cubic inches by use of a geared supercharger.
The Daimler-Benz DB 601 was a German aircraft engine built during World War II. It was a liquid-cooled inverted V12, and powered the Messerschmitt Bf 109, Messerschmitt Bf 110, and many others. Approximately 19,000 601's were produced before it was replaced by the improved Daimler-Benz DB 605 in 1942.
The Savoia-Marchetti SM.81 Pipistrello was the first three-engine bomber/transport aircraft serving in the Italian Regia Aeronautica. When it appeared in 1935, it represented a real step ahead in Italian military aviation: it was fast, well armed and had a long range. It proved effective during the war with Ethiopia and the Spanish Civil War. Despite being too slow to remain competitive as a bomber in the later years of World War II, it was one of the most flexible, reliable and important aircraft of the Regia Aeronautica from 1935 to 1944, and adapted to second-line duties in a wide range of tasks.
The Savoia-Marchetti S.73 was an Italian three-engine airliner that flew in the 1930s and early 1940s. The aircraft entered service in March 1935 with a production run of 48 aircraft. Four were exported to Belgium for SABENA, while seven others were produced by SABCA. The main customer was the Italian airline Ala Littoria.
The Savoia-Marchetti SM.82 Marsupiale was an Italian bomber and transport aircraft of World War II. It was a cantilever, mid-wing monoplane trimotor with a retractable, tailwheel undercarriage. There were 875 built, the first entering service in 1940. Although able to operate as a bomber with a maximum bombload of up to 8,818 lb (4000 kg), the SM.82 saw very limited use in this role. The SM.82 was the foreign aircraft used in largest number by the Luftwaffe, which operated several hundreds of this aircraft, as a transport. Post-war about 30 SM.82s continued in service with the Aeronautica Militare Italiana, many remaining in service until the early 1960s.
The Breda Ba.64 was an Italian single-engine ground-attack aircraft used by the Regia Aeronautica during the 1930s.
The Savoia-Marchetti SM.85 was an Italian monoplane dive bomber and ground-attack aircraft that served in small numbers in the Regia Aeronautica at the beginning of World War II. They were soon replaced in service by the Junkers Ju 87.
The Savoia-Marchetti SM.83 was an Italian civil airliner of the 1930s. It was a civilian version of the Savoia-Marchetti SM.79 bomber.
The Savoia-Marchetti SM.89 was an attack aircraft designed by Alessandro Marchetti and built by Savoia-Marchetti. Only one example was built, the prototype (MM.543).
The Savoia-Marchetti SM.95 was an Italian four-engine, mid-range transport aircraft, which first flew in 1943. It was the successor of the Savoia-Marchetti SM.75.
The Savoia-Marchetti SM.78 was an Italian bomber/reconnaissance biplane flying boat of the early 1930s.
The Caproni Ca.101 was a three-engine Italian airliner which later saw military use as a transport and bomber. It was designed in 1927 and first flown in 1928.
The Breda Ba.201 was an Italian dive bomber designed during World War II, that never entered production.
Alfa Romeo built/designed a range of aircraft engines based on the Bristol Jupiter and Bristol Pegasus designs, designated Alfa 125, Alfa 126, Alfa 127, Alfa 128, Alfa 129 and Alfa 131. All these essentially similar engines were mainly fitted to Italian bombers in World War II, Alfa Romeo building around 11,000 units between 1934 and 1944
The Alfa Romeo 135 Tornado was an Italian 18-cylinder radial engine designed by Giustino Cattaneo in 1934–1935.
The Savoia-Marchetti S.59 was a 1920s Italian reconnaissance/bomber flying boat designed and built by Savoia-Marchetti for the Regia Aeronautica.
The Savoia-Marchetti S.71 was an Italian eight-passenger light transport designed and built by Savoia-Marchetti. The S.71 was a three-engine, high-wing cantilever monoplane with a fixed tailwheel landing gear. It had a crew of four and room for eight passengers. The first four aircraft were powered by three 190 kW (260 hp) Walter Castor II radial engines, but the last three had 276 kW (370 hp) Piaggio P.VII engines.
The Breda Ba.46 was a three-engined Italian bomber transport, developed from a similar but lower-powered civil transport. It was designed in Italy in the mid-1930s for colonial policing but not put into production.
The Savoia-Marchetti SM.80 is a two-seat monoplane amphibian tourer, with a single, tractor engine mounted above the wing, designed in Italy in the early 1930s. The SM.80bis is a four-seat variant, powered by two pusher engines.
The Walter Sagitta was a Czechoslovakian, air-cooled, inverted V-12 engine that first ran in 1937. This was one of several smaller, low-mass medium power pre-war V-12 engines produced. With a displacement of 18.4 liters, it produced up to 373 kW at 2,500 rpm.
