Clerget aircraft engines
Clerget was the name given to a series of early rotary aircraft engine types of the World War I era that were designed by Pierre Clerget(fr). Manufactured in France by Clerget-Blin and in Great Britain by Gwynnes Limited they were used on such aircraft as the Sopwith Camel and Vickers Gunbus.
In the 1920s Pierre Clerget turned his attention to diesel radial engines and finally produced a H-16 engine before he died in 1943.
