Armstrong Siddeley Serval

Armstrong Siddeley Serval

The Armstrong Siddeley Serval was an aero engine developed by Armstrong Siddeley in the 1920's. Following the company tradition the engine was named after the Serval wild cat.

Design and development

The Serval was a ten-cylinder, double-row, air-cooled radial piston engine. It was developed from the Armstrong Siddeley Mongoose and was, more or less, two Mongooses built around a single crankcase. In fact, it first appeared as the Double Mongoose in May 1928. [Gunston 1989, p.17.]

Built in several variants, power output was about 340 hp (254kW).
