The Vedeneyev M14P is a Russian nine-cylinder, four-stroke, air-cooled 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.
