Klimov-TV3-117

 

The Klimov TV3-117 is a Russian gas turbine aero engine first run in 1974. It is used in most medium lift, utility, and attack helicopters designed by the Mil and Kamov design bureaus. The TV3-117 turboshaft engine was developed in 1974 and later the TV3-117 was installed on 95% of all helicopters designed by Mil and Kamov Engineering Centre. The engine has been produced in many variants, with over 25,000 built.

Despite the similar designation, the TV7-117 engine family is new and unrelated to the TV3-117.
