It maintains the propulsion power under high and hot conditions to higher ambient temperature as compared to the TV3-117 engine early modifications, which improves significantly the performance of helicopters. The engine automatic control system permits to set the takeoff power within the range of 2,000 to 2,500 hp (depending on the engine application). All engine versions provide 2,800 hp in the contingency power condition.
The engine has been developed capable of updating nearly all TV3-117 family engine versions now in service to the TV3-117VMA-SBM1V, standard retaining their interchangeability.
The engine guarantees the retention of high flight performance of helicopters even if they are equipped with high-efficiency dust-protecting and exhaustshielding devices.
