The Renault 438, frequently referred to as the Coupe Deutsch 1934, was a French racing powerplant engineered specifically for aircraft participating in the Coupe Deutsch de la Meurthe competition.
Design and development
Derived from the Renault 6P and Renault 6Q models, the 438 integrated a turbo-supercharger with cylinders featuring a narrow bore and elevated compression ratio, while adopting the crankcase architecture from the 6Q.
Operational history
The 438 engine powered only two unique aircraft: F-AMVA, a Caudron C.430/1 Rafale crafted for racing and record-setting efforts including the Coupe Deutsch, and the Hanriot H.183 F-AOJG, an aerobatic variant of the Hanriot H.180 series.
