Bristol Siddeley was formed by Bristol taking over Armstrong Siddeley, rebranding several of the engines. It took over de Havilland engines and, in turn, became a division of Rolls-Royce Limited.

: Cite uses generic title (help)The Amiot 354 was the last in a series of fast, twin-engine bombers which fought with the French Air Force in limited numbers during the Battle of France.
The Hispano-Suiza 12Y was an aircraft engine produced by Hispano-Suiza for the French Air Force before the Second World War. The 12Y became the primary French 1,000 hp (750 kW) class engine and was used in a number of famous aircraft, including the Morane-Saulnier M.S.406 and Dewoitine D.520.
The Rolls-Royce Olympus was the world's second two-spool axial-flow turbojet aircraft engine design, first run in May 1950 and preceded only by the Pratt & Whitney J57, first-run in January 1950. It is best known as the powerplant of the Avro Vulcan and later models in the Concorde SST.
The Rolls-Royce RB.44 Tay is a British turbojet engine of the 1940s, an enlarged version of the Rolls-Royce Nene designed at the request of Pratt & Whitney. It saw no use by British production aircraft but the design was licence built by Pratt & Whitney as the J48, and by Hispano-Suiza as the Verdon.
The Hawker Fury is a British biplane fighter aircraft used by the Royal Air Force in the 1930s. It was a fast, agile aircraft, and the first interceptor in RAF service faster than 200 mph (320 km/h) in level flight. It was the fighter counterpart to the Hawker Hart light bomber.
The Bristol F.2 Fighter is a British First World War two-seat biplane fighter and reconnaissance aircraft developed by Frank Barnwell at the British and Colonial Aeroplane Company later known as the Bristol Aeroplane Company. It is often simply called the Bristol Fighter, "Brisfit" or "Biff".
The Wright R-1820 Cyclone 9 is an American radial engine developed by Curtiss-Wright, widely used on aircraft in the 1930s through 1950s. It was produced under license in France as the Hispano-Suiza 9V or Hispano-Wright 9V, and in the Soviet Union as the Shvetsov M-25.
The Sunbeam Arab was a British First World War-era aero engine.
The Rolls-Royce Gem is a turboshaft engine developed specifically for the Westland Lynx helicopter in the 1970s. The design started off at de Havilland Engine division and passed to Bristol Siddeley as the BS.360. Rolls-Royce bought out Bristol Siddeley in 1966 and after it dropped the Bristol Siddeley identity the engine became the RS.360.
Morane-Saulnier MoS-50 was a French parasol configuration trainer aircraft built in 1924. The twin-seat aircraft was of wooden construction and was one of the last aircraft to have a rotary engine, a 97 kW (130 hp) Clerget 9B.
The Wolseley Viper is a British-built, high-compression derivative of the Hispano Suiza HS-8 liquid-cooled V-8 engine, built under licence by Wolseley Motors during World War I.
The I.Ae.24 Calquin was a tactical bomber designed and built by the Instituto Aerotécnico at Córdoba, in Argentina in the immediate post-World War II era. Although superficially a "look-alike" for the de Havilland Mosquito, the I.Ae.24 was powered by twin Pratt & Whitney R-1830-G “Twin Wasp” radials giving it a distinct appearance. After an operational career spanning two decades, the Calquin was retired.
The Hispano-Suiza 14AB, a.k.a. Hispano-Suiza Type 80, was a 14-cylinder twin-row air-cooled radial engine. In 1929 the Hispano-Suiza company bought a license to produce the Wright Whirlwind engine. The technology from that engine was used to produce a number of different radial engines with greater displacements, power, and number of cylinders.
The Bristol Tourer was a British civil utility biplane produced in the years following the First World War, using as much as possible from the design of the Bristol Fighter aircraft. Bristol Tourers were delivered with a variety of engines, subject to availability and customer desires; these included the Rolls-Royce Falcon, Siddeley Puma, Hispano-Suiza 8, and Wolseley Viper. Many Tourers were fitted with a canopy to cover the one or two passenger seats in the rear cockpit, giving the type its original name of Coupé. The pilot's cockpit, however, remained open.
The Armstrong Siddeley Deerhound was a large aero engine developed by Armstrong Siddeley between 1935 and 1941. An increased capacity variant known as the Boarhound was never flown, and a related, much larger, design known as the Wolfhound existed on paper only. Development of these engines was interrupted in April 1941, when the company's factory was bombed, and on 3 October 1941 the project was cancelled by the Air Ministry.
The Wright Whirlwind was a family of air-cooled radial aircraft engines built by Wright Aeronautical. The family began with nine-cylinder engines, and later expanded to include five-cylinder and seven-cylinder varieties. Fourteen-cylinder twin-row versions were also developed, but these were not commercially produced.
The Stampe et Vertongen RSV.22 was a training biplane produced in Belgium in the 1920s.
The Hispano-Suiza 18R was an eighteen cylinder high performance water-cooled piston engine, in an 80° W or broad arrow layout, for use in racing aircraft, built in France during the latter half of the 1920s.
