Rostec develops the M105, a piston engine for light aviation, aiming to replace imports following the embargo
The Russian state-owned corporation Rostec has announced the development of a new piston engine designed for light aviation, in a strategic move to reduce dependence on imported components after restrictions imposed by international sanctions.
The project is being led by ODK (United Engine Corporation), a subsidiary of the group specializing in aircraft engines. The new power unit, designated M105, was conceived primarily to serve light civil aircraft — a segment considered promising and experiencing growing demand within the Russian domestic market.
Technical specifications
The M105 engine features the following key characteristics:
- Power output: 115 horsepower
- Displacement: 1,211 cm³
- Weight: 75 kg
- Dimensions: Compact, designed for simplified integration into light aircraft
According to the company, the unit combines low structural weight and optimized operational volume — factors considered critical for efficiency and performance in small aircraft.
Planned applications
The M105 was designed for multiple applications in light aviation. In airplanes, it may be used for:
- Driving electrical generators
- Propulsion via tractor or pusher propellers
- Power transmission to auxiliary systems
In addition to the standard version, Rostec is also developing the M105V modification, intended specifically for small helicopters and autogyros.
Import substitution strategy
According to Rostec, the new engine offers competitive technical characteristics compared to foreign models traditionally used in the Russian market. The initiative is part of a broader import substitution strategy in the aerospace sector, intensified after international embargoes affected the Russian industry’s supply chain.
The development of domestic engines for light aviation is seen as an important step toward ensuring technological autonomy and operational continuity in the small civil aviation segment.
