AI-450 Turboshaft Engine

Designed to be used as a propulsion power plant for helicopters of different application with loadcarrying capacity 1500 to 2000 kg (Ka-226 with AI- 450 engines and others).
The engine design employs a two-rotor scheme including a gas generator rotor and a free turbine rotor. The free turbine transmits power to the main gearbox, which is installed in front of the engine, through a shaft, which passes inside the gasgenerator rotor shaft.

The engine consists of three modules:
- generator (engine air inlet section, compressor, combustion chamber and compressor turbine); 
- reduction gear with accessory drive gearbox; 
- free power turbine.
