TV3-117VMA-SBM1V, Series 1
It is used for installation in multi-purpose medium-utility helicopters. The takeoff power ranges from 2,000 to 2,500 hp. The TV3-117VMA-SBM1V, Series 1, engine was designed on the basis of certified engine TV3-117VMA-SBM1V by using the updated full authority digital engine control, which makes it possible to:
increasing precision of maintenance and limitation of engine operation parameters
exclude the horizontal drive of the free turbine speed governor from the engine design;
keeping a record of engine service life in different power ratings
realizing engine anti-surge protection algorithm
implementing torque measurement system into engine design
