TheRolls-Royce Falcon is anaero engine developed in 1915. It was a smaller version of theRolls-Royce Eagle, a liquid-cooled V-12 of 867cu in (14.2L)capacity. Fitted to many BritishWorld War I-era aircraft, production ceased in 1927. The Falcon was designed by R.W. Harvey-Bailey.[1]
An airworthy Falcon survives today and powers aBristol F.2 Fighter during summer displays.
Production of the Falcon began in September 1916 and was so successful that it was also manufactured under licence byBrazil Straker in Bristol.[2] Production continued until 1927, by which time 2,185 had been built.[3]
An unusual feature of this engine was theepicyclic propeller reduction gear which contained aclutch designed to limit the maximumtorque, thus protecting the reduction gears.[4]
