The ADC Airdisco is a British V8 aero engine that first ran in 1925.
The 'Airdisco' was developed from the Renault 80 hp aero engine by Frank Halford of the Aircraft Disposal Company, the main difference being the use of aluminium cylinder heads. Halford later used one bank of cylinders to create the Cirrus engine.[1]
