“TV7-117V engine is designed for Mi-38 type utility helicopters. The approvals of major modification of the type design obtained this month are aimed at the extension of the TV7-117V operating conditions. We use the helicopter modification improvement experience in our work on the TV7-117ST-01/02 airliner modifications intended for domestic regional airliners,” pointed out Vsevolod Eliseev, General Designer of UEC-Klimov.
The approved modifications are the next stages of the performance improvement plan for the TV7-117V and all engines from the TV7-117 family.
