Granville Bradshaw

Granville Eastwood Bradshaw OBE, AFRAeS (1887–1969) was an English engineer and inventor who designed motorcycle, auto, and aero-engines.

The ABC radial aero-engines designed and built during the First World War were extremely advanced and the government placed large orders for the Dragonfly.

A number of aircraft were designed to use the Dragonfly, but the engines were plagued by problems and failed to live up to the promises.

The design was taken over by the Royal Aircraft Establishment at Farnborough to try to resolve the issues, but with the end of the war, it was abandoned.
