Description
AI-9V is an auxiliary gas-turbine engine (APU) designed to provide autonomous power and air supply to helicopters both on the ground and in flight. The unit delivers compressed air to start the main engines (TV3-117 family) and supplies electrical power to the onboard network, enabling system checks and ground operation without running the main propulsion engines.
The AI-9V is installed on Mi-8/Mi-17/Mi-171, Mi-24, Mi-28, Ka-32, Ka-50 and Ka-52 helicopters, allowing engine start capability at remote landing sites and providing emergency electrical backup in case of main generator failure. The APU reduces wear on the primary engines and increases operational independence of the aircraft.
The engine is a single-shaft gas turbine with a centrifugal compressor and combustion chamber. It operates on standard aviation kerosene fuels (T-1, TS-1, RT). Bleed air extracted from the compressor drives pneumatic starters, while an integrated generator delivers up to 3 kW of electrical output at 27 V DC.
Alternate designations: AI-9V, AI9V, АИ-9В, АИ9В — all refer to the same auxiliary power unit.
