The Gnome-Rhône 9K Mistral was an air-cooled radial engine featuring nine cylinders, delivering power output ranging from 550 hp (405 kW) up to 700 hp. This model was developed by expanding the Gnome-Rhône 7K design with the addition of two extra cylinders.
Design and development
Originating from the Gnome-Rhône 5K, itself a licensed adaptation of the Bristol Titan, the 7K represented a scaled-up version with updated cylinder designs, as denoted by the 'K' suffix. The 9K served as a precursor to the more robust twin-row, 14-cylinder Gnome-Rhône 14K engine.
Manufacturing under license occurred at Hungary’s Weiss Manfréd Repülogép- és Motorgyár Rt. (WM Rt), and in the Soviet Union it was produced as the M-75 at GAZ-29 located in Zaporozhye. Production numbers remained modest, as focus shifted towards the Shvetsov M-25—a licensed version of the Wright Cyclone—and the M-85, which was based on the Gnome-Rhône 14K Mistral Major.
