The Armstrong Siddeley Genet Major is a British five-cylinder (later seven-cylinder), air-cooled, radial engine for aircraft, designed and built by Armstrong Siddeley and first run in 1928. It developed 140 horsepower (104 kW). In Royal Air Force use the seven-cylinder version was known as the Civet I. The Feliform names used are in line with company convention, the Genet and Civet[1] both being large cat-like carnivores.
