Gnome-Rhône 9K


The Gnome-Rhône 9K Mistral was a nine-cylinder 550 hp to 700 hp air-cooled radial engine, that started life as an enlarged Gnome-Rhône 7K with two extra cylinders.

Design and development

The Gnome-Rhône 7K itself was an enlarged version of the Gnome-Rhône 5K which was derived from a licensed version of the Bristol Titan. A redesign of the cylinders is indicated by the K suffix. The 9K was followed by the larger and more powerful 14-cylinder twin row Gnome-Rhône 14K.
The 9K was license produced by Hungarian company Weiss Manfréd Repülogép- és Motorgyár Rt.. The engine was used successfully in the MÁVAG Héja and Weiss WM-21 Sólyom aircraft. The 9K was also produced in the Soviet Union as the M-75 at GAZ-29 in Zaporozhye. Only small numbers were built and it was dropped in favor of the M-25 a version of the Wright Cyclone and the M-85 a version of the Gnome-Rhône 14K Mistral Major.
