LOM PRAHA has a long history of production of aircraft engines, which goes back to 1915. Development and production of piston aircraft engines has been a long and successful tradition in the Czech Republic. With world famous manufacturers such as Walter, Mortorlet Praha, Praga and Avia Praha all producing engines and propellers for aircraft manufacturers the world over. In 1989 the production and development of aircraft inverted piston engines from these companies was transferred to the newly formed LOM PRAHA group.

 

LOM PRAHA manufactures 4 and 6 cylinder inverted inline aircraft piston engines from 120 to 250HP. The LOM engines build on the tradition of the Walter and Motorlet engines, with advantages which in particular include cost-effective operation and the possibility to use automotive (mogas) fuel, high power to weight ratio, narrow frontal area and an oil system enabling acrobatic flight. LOM engines are used by Zlin aircraft in many of their production models including trainers for the military. 

The LOM engine timeless design and exceptional quality makes these engines not only suitable for modern aircraft, but also for historic and replica aircraft. These engines have been successfully used in aircraft such as Cessna 172s, RVs, Tiger Moths, CH 801s, Esprit VF-II SCs, Bücker Bü 131s, Ryan STAs, Ryan Replicas, Scale Spitfire Replicas, Scale P51 Mustang Replicas and many others.
