Rolls-Royce Goshawk

The Rolls-Royce Goshawk was a development of the Rolls-Royce Kestrel featuring evaporative cooling. It provided 660 h.p. and powered the Short Knuckleduster, the Supermarine Type 224 (a predecessor to the Supermarine Spitfire [ [http://www.spitfiresociety.demon.co.uk/rjmitchl.htm History of the Spitfire] ] ) and other prototypes.

Design and development

Developed from the Kestrel IV, the evaporative or steam cooling version was named Goshawk. Twenty engines were built and they flew only in prototypes as a few manufacturer's private ventures and "one offs". Powers for individual installations are quoted between 650 and 700hp.

Applications

The Goshawk was the power unit specified for the twin engined Short Knuckleduster flying boat (K3574) to Specification R24/31 and "preferred" for the Blackburn F3 (K2892), Bristol Type 123, Hawker P.V.3, Supermarine Type 224 (K2890) and the Westland PV4 biplane (K2891) to Fighter specification F7/30

It also powered the private venture Hawker "Intermediate Fury" (G-ABSF) and the Westland Pterodactyl V (K2770) and was installed for trials in the Gloster TSR38 (S1705), the first Gloster Gnatsnapper prototype (N227) and the Hawker High Speed Fury (K3586)
