TV3-117VMA-SBM1V, Series 4E
It is designed for remotorization of Mi-8T helicopters by replacing the TV2-117 engines. Compared with helicopters powered by TV2-117 engines, TV3-117VMA-SBM1V engines can keep their power up to high environment temperatures and high altitudes of location and flight. A number of power conditions have also been implemented to ensure safe takeoff, continued flight and landing of the helicopter with one engine inoperative. |

Main advantages of the engine:
- high reliability;
- increased power maintained in hot and high conditions;
- low SFC;
- long service life;
- easy in-service maintenance;
- high repairability;
- stable operation under conditions of heavy smoke and dust;
- low cost of life cycle.
