The Rolls-Royce Falcon is an aero engine developed in 1915. It was a smaller version of the Rolls-Royce Eagle; a liquid cooled V-12 of 867 cu in (14.2 L) capacity. Fitted to many British World War I era aircraft, production ceased in 1927.

An airworthy Falcon survives today and powers a Bristol F.2 Fighter during summer displays.

Design and development

Production of the Falcon began in September 1916 and was so successful that it was also manufactured under licence by Brazil Straker in Bristol.

An unusual feature of this engine is the epicyclic propeller reduction gear which contains a clutch designed to limit the maximum torque, thus protecting the reduction gears.

The Falcon was notably used in the Bristol F.2 Fighter and Blackburn Kangaroo bomber.
