Granville Bradshaw
Granville Eastwood Bradshaw OBE, AFRAeS (1887–1969) was an English engineer and inventor who designed motorcycle and aero-engines.
History
Bradshaw was born in Preston, Lancashire in 1887 as the son of William and Annie Bradshaw. His father was a jeweler and optician.
Bradshaw's early work was involved with the early pioneers of flight, which led him to become an expert on stressing. He designed the Star Monoplane including the engine for Star Aircraft when he was 19, which he later flew. He then started to work on aero-engines and was the co-founder of the All-British Engine Company (later ABC Motors then Walton Motors).
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.
