AI9-3B
- AI-9V - Engine with starter-generator, designed as a separate unit, has its own fuel equipment, autonomous oil system and regulation system. Used in flight and on the ground to supply air to the engine launch systems of the Mi-8 MT , Mi-17 , Mi-24 , Mi-28 , Mi-35 , Ka-50 , Ka-52 helicopters and to power the on-board network when checking the radio and electrical equipment. At Motor Sich JSC, 3,600 Armed Forces AI-9V were released
- AI9-3B - installed on the An-140 . Designed to generate compressed air when running TV3-117VMA-SBM1 and another, also for forcing air into air conditioning systems and driving an electric generator.

Features
- When turned off, the AI-9 produces a strong, sharp and piercing short-term sound (“pi-y”), characteristic only for this engine.
- At the start of a very strong possible vibration of the engine, disappearing with the promotion. Also, when a failed or restarted without intermediate scrolling, there is often a “flare” - the flames burst out of the nozzle for a short time, sometimes quite significant.
