Rolls-Royce Kestrel VI (690hp)
1934, Brooklands Aircraft Factory, On long term display
The Kestrel series of engines proved successful with nearly 2,000 built and established the pattern for Rolls-Royce’s later piston-engine designs. It was used in a large number of British aircraft, most notably the Brooklands-built family of Hawker biplanes such as the Fury, Hart, Demon and Osprey which formed the backbone of the RAF in the 1930s.
Exported versions of the engine even powered the prototypes of German designs such as the Junkers Ju 87 ‘Stuka’ and Messerschmitt Bf 109a which were to be used against British forces to great effect during the Second World War.
This supercharged example is fitted with a cropped two-blade wooden ‘Watts’ propeller of 1936 and has been partially sectioned.
