The Siddeley Tiger was an unsuccessful Britishaero engine developed shortly after the end of World War I by Siddeley-Deasy. Problems encountered during flight testing caused the project to be cancelled.
Developed using two modified cylinder banks from the Siddeley Puma, the Tiger was a liquid-cooled 60-degree V12 engine with the advanced feature of an electric starter motor protected by a friction clutch. A reduction gear arrangement was provided for the propeller drive with a ratio of 0.559:1. The company claimed a power output of 600 hp (447 kW) but this was regarded as optimistic.[1] Flight testing by a Royal Aircraft Establishment test pilot, Frank Courtenay, revealed problems and his opinion of the engine was low as the following quote shows:
'The engines could never be persuaded to run simultaneously for any length of time'
— Frank T.Courtenay, Lumsden – British Aero-Engines and Their Aircraft
Application and cancellation
The Tarrant Tabor, a giant triplane bomber was designed to use the Tiger but redesigned to use other engines when it became clear the Tiger would not be available soon enough. The only aircraft in which the Siddeley Tiger flew was the ill-fated prototype of the twin-engined Siddeley-Deasy Siniai of which three were planned to be produced. Major problems with both the engines and this experimental bomber aircraft led to cancellation of the projects.[2]
