The Potez 8D represents the most powerful unit within the Potez D family of air-cooled piston aircraft engines. This supercharged inverted V engine, comprising eight cylinders, delivers a takeoff output of .
Design and development
During the 1930s, Potez embarked on developing a new line of engines to succeed their Anzani-based radial engines. The four-cylinder inverted inline Potez 4D was operational before World War II but only entered production in the late 1940s, followed by the six-cylinder Potez 6D and ultimately the eight-cylinder inverted-V 8D. These D-series engines utilized common components including pistons, cylinders, bore, stroke, and valve mechanisms. The larger 8D model incorporated an upgraded lubrication system and unique connecting rod designs tailored for its 90° V-cylinder layout.
The 8D.32 version was installed in the prototype of the Potez 75 ground attack aircraft; nevertheless, funding reductions in 1957 resulted in the termination of both pre-production and full production contracts.
