de Havilland Gipsy Major 1
1934, -, Not currently on display
Designed by Brooklands racing driver Frank Halford and built by the de Havilland Aircraft Company, this well-known aero-engine design was developed from the Gipsy III. Unlike earlier Gipsy engines, the Major is inverted: having the crankshaft at the bottom gives a better ground clearance for the propeller and a better view for the pilot. The Gipsy Major is best known for powering De Havilland’s pre-war Tiger Moth biplane and post-war Chipmunk trainers.
This particular engine has an unknown history but was probably fitted to a Chipmunk before being retired and transferred to Southall Technical College and professionally sectioned for training purposes as a typical light aircraft powerplant.
