Armstrong Siddeley Tiger

Armstrong Siddeley Tiger at the Science Museum in London .

The Armstrong Siddeley Tiger is an aircraft engine that the British manufacturer Armstrong Siddeley built from 1932. The two-row 14-cylinder radial engine has a displacement of 32,692 cm³. The Tiger was developed from the Jaguar model. There were a number of variants, but they only differed slightly from the basic model in terms of performance and size. The Tiger VIII was the first British aircraft engine with a compressor that could run at two different speeds.
