Klimov TV2-117

The Klimov TV2-117 (initially Isotov TV2-117) is a Soviet gas-turbine turboshaft engine intended for helicopter use. Designed in the early 1960s by the Isotov Design Bureau the engine became the first purpose built gas turbine engine for helicopter use by the Soviet Union with previous helicopter turbines being adapted aeroplane powerplants. It was later produced by Klimov, production ending in 1997.
