Clerget aircraft engines

Clerget is the name given to aircraft engines designed by the French engineer Pierre Clerget(fr) in the first half of the 20th century.

From 1910 to 1913 a series of, Clerget badged, inline-four and V8 aero-engines were manufactured and marketed by the Clément-Bayard automobile firm.

From 1912, Pierre Clerget focused his efforts on developing a series of rotary aircraft engines and founded a new company, Clerget-Blin in 1913. During World War I, more than 30,000 Clerget rotary engines were manufactured in France and the United Kingdom with the type powering many aircraft including the majority of Sopwith Camels.

Following the bankruptcy and liquidation of Clerget-Blin in 1920, Pierre Clerget joined the Service Technique de l'Aéronautique (STAé) where he specialised in the design of aircraft diesel engines up until his death in 1943.
