TV3-117VM Series 3

TV3-117VM Series 3 is a reliable turboshaft aircraft engine designed for civil helicopters, primarily of the Mi-8 / Mi-17 family. The engine provides high fuel efficiency, stable power output, and enhanced operational reliability across a wide range of climatic conditions. It represents a further development of the base TV3-117 engine family with improved performance characteristics.

The Series 3 designation indicates an upgraded modification featuring enhanced operational capabilities, including improved power retention in hot and high-altitude conditions. The engine is optimized for operation in demanding environments while maintaining long service life and high reliability.

TV3-117VM Series 3 is intended for installation on helicopters with single-rotor and coaxial rotor configurations. The engine ensures preservation of helicopter flight performance when equipped with inlet particle separators (IPS) and exhaust screening devices. Its design allows modernization of earlier TV3-117 family engines to this configuration while maintaining interchangeability.

The engine demonstrates stable operation in dusty and smoky atmospheric conditions, supports long-term operation in maritime environments, and offers low specific fuel consumption. High maintainability, repairability, and a low life-cycle cost make the TV3-117VM Series 3 suitable for long-term civil helicopter operation.

TV3-117VM Series 3 consists of a 12-stage axial compressor, an annular combustion chamber, a two-stage compressor turbine, a two-stage free turbine, an exhaust unit, and an accessory gearbox. Engine operation is supported by integrated anti-icing, lubrication and breather, fuel supply and automatic control, engine control and monitoring, and starting systems.
