Carden Aero Engines Limited was a 1930s British fixed-wing aero-engine manufacturer, based at Heston Aerodrome.
Sir John Carden established the company in March 1936, while the Flying Flea craze was sweeping Britain.
He saw a need for a cheap low-powered propulsion unit for ultralight aircraft.
Following the death of Sir John in an air accident in December 1935, the company was taken over by Carden-Baynes Aircraft Ltd, and later sold to Chilton Aircraft Ltd, Chilton Foliat, near Hungerford, Berkshire.
Aircraft that have used the Carden-Ford 31 hp engine are: Broughton-Blayney Brawney, B.A.C.
