The Armstrong Siddeley Genet was a five-cylinder, air-cooled, radial engine for aircraft use built in the UK, first run in 1926. It developed 80 hp at 2,200 rpm in its final form and was a popular light aircraft powerplant. Following the company tradition with a slight deviation the engine was named after the Genet, a catlike animal of the same order but different family.[1]
