Vedeneyev M14P

The Vedeneyev M14P is a Russian nine-cylinder, four-stroke, air-cooled, petrol-powered radial engine. Producing 360 hp (268 kW), its design dates from the 1940s (Kotelnikov 2005), and is itself a development of the Ivchenko AI-14 engine. The M14P has recently become increasingly popular in experimental aircraft and kit designs such as the Murphy Moose, Radial Rocket, Pitts Model 12, and others. Historically, the engine has been used extensively by the Yakovlev and Sukhoi Design Bureaus.

The M14PF is a 400 hp (298 kW) version of the M14P.

Design and development

The engine's intake system uses a gear driven supercharger and an automatic-mixture type carburetor. Power is transmitted to the propeller via a reduction gearbox.

In addition to the carburetor, the engine has a speed governor, two magnetos, mechanical fuel pump, generator, and an oil pump. It is started pneumatically, and remains fully operational during inverted flight. Unlike most Western aero-engines, which turn to the right (clockwise) when viewed from the cockpit, the M14P rotates to the left (counter-clockwise).
