United Engine Corporation included in Rostec State Corporation first showcases a new product, the М105 propulsion for small aircraft, at NAIS 2026. The new piston engine has compact dimensions and low weight as well as competitive specifications and performance. 

The M105 is a turbocharged four-stroke four-cylinder aircraft piston engine. The engine was created by UEC and is designed to be mounted on civilian light aircraft. The M105V version is intended for civilian light helicopters and autogyro. It can be used to drive generators and pusher or tractor propeller, and to transfer the developed thrust. 

The piston engine has competitive specifications: power - 115 hp, displacement - 1211 cm3 and stroke - 61 mm. Advantages of the M105 include its performance. Total service life limit — 2000 hours, time between overhauls — 750 hours, life — 10 years. The engine has quite compact dimensions and a weight of 75 kg in real configuration. 

The 13th National Aviation Infrastructure Salon, NAIS 2026, is held on 4-5 February at Crokus Expo in Moscow. UEC’s stand showcases the M105 piston engine and the advanced PD-8 propulsion system for the Superjet and Be-200 aircraft.
