The de Havilland Gipsy Major or Gipsy IIIA is a four-cylinder, air-cooled, inverted inline engine used in a variety of light aircraft produced in the 1930s, including the famous Tiger Moth biplane. Many Gipsy Major engines still power vintage aircraft types worldwide today.
Major Frank Bernard Halford CBE FRAeS was an English aircraft engine designer. He is best known for the series of de Havilland Gipsy engines, widely used by light aircraft in the 1920s and 30s.
The Cirrus and Hermes or Cirrus-Hermes are a series of British aero engines manufactured, under various changes of ownership, from the 1920s until the 1950s. The engines were all air-cooled, four-cylinder inline types, with earlier ones upright and later designs inverted.
The Armstrong Siddeley Cheetah is a seven-cylinder British air-cooled aircraft radial engine of 834 cu in capacity introduced in 1935 and produced until 1948. Early variants of the Cheetah were initially known as the Lynx Major.
The Armstrong Siddeley Jaguar was an aircraft engine developed by Armstrong Siddeley. The Jaguar was a petrol-fuelled air-cooled 14-cylinder two-row radial engine design. The Jaguar III was first used in 1923, followed in 1925 by the Jaguar IV and in 1927 by the Jaguar VI. In 1925 the Jaguar became the first production aero engine incorporating a geared supercharger.
The de Havilland Gipsy Twelve was a British aero engine developed by the de Havilland Engine Company in 1937. Approximately 95 were manufactured. It was known as the Gipsy King in Royal Air Force service.
The RAF 1 was a British air-cooled, V-8 engine developed for aircraft use during World War I. Based on a French design, it was developed at the Royal Aircraft Factory, and built by six different British companies including Daimler, Rolls-Royce and Wolseley Motors Limited.
The de Havilland Gipsy is a British air-cooled four-cylinder in-line aircraft engine designed by Frank Halford in 1927 to replace the ADC Cirrus in the de Havilland DH.60 Moth light biplane. Initially developed as an upright 5 litre capacity engine, later versions were designed to run inverted with increased capacity and power.
The Blackburn Cirrus Minor is a British four-cylinder, inverted, in-line air-cooled aero-engine that was designed and built by the Cirrus Engine Section of Blackburn Aircraft Limited in the late 1930s.
The Blackburn Cirrus Major is a British, inline-four aircraft engine that was developed in the late 1930s.
The ADC Cirrus is a series of British aero engines manufactured using surplus Renault parts by the Aircraft Disposal Company (ADC) in the 1920s.
The de Havilland Gipsy Minor or Gipsy Junior was a British four-cylinder, air-cooled, inline engine used primarily in the de Havilland Moth Minor monoplane, both products being developed in the late 1930s.
The Blackburn Cirrus Bombardier was a British four-cylinder inline aircraft engine, developed and built by the Blackburn Aircraft company in the mid-1950s. The engine featured fuel injection.
The ADC Airdisco is a British V-8 aero engine that first ran in 1925.
The ADC Nimbus was a British inline aero engine that first ran in 1926. The Nimbus was developed from the Siddeley Puma aero engine by Frank Halford of the Aircraft Disposal Company, the goal was to develop the Puma to produce its intended power output which Halford eventually achieved. The Nimbus was further developed into an air-cooled version known as the ADC Airsix which did not enter production and was not flown.
The Blackburn Cirrus Midget was a British four-cylinder, inverted, inline air-cooled aero engine designed and built in 1937 by the Cirrus Engine Section of Blackburn Aircraft Limited. Little is known of its development and use, its sole aircraft application being reported as the Chilton D.W.1 although it is possible that this did not transpire.
The Renault 70 hp or Type WB was a French V-8 aero engine that first ran circa 1907. It was also manufactured under license by Renault Limited of West Brompton, London between August 1914 and December 1918, three other companies, including Rolls-Royce, also produced the engine. A variant known as the Type WC used an external oil pump as opposed to the internal pump of the Type WB. The Renault V-8 engines were noted as inefficient but reliable, the inefficiency being mainly due to the excessively rich fuel/air mixture used to assist cooling.
The Renault 80 hp, or Type WS in British service, was a V-8 aero engine that first ran in 1914. The engine was manufactured in Britain by Renault Limited of West Brompton, London between August 1914 and December 1918, seven other companies, including Rolls-Royce and Brazil Straker, also produced the engine. The Renault V-8 engines were noted as inefficient but reliable, the inefficiency being mainly due to the excessively rich fuel/air mixture used to assist cooling.
The de Havilland Iris was a British four-cylinder, liquid-cooled, horizontally opposed aero engine. Notable as the first aero engine to be designed by Geoffrey de Havilland it was produced in small numbers between 1909 and 1910 by Iris Cars Ltd of Willesden from which it took its name.
