Klimov TV7-117
The Klimov TV7-117 is a Russian turboprop engine certified in 1997 to power the Ilyushin Il-114 regional commuter aircraft. The new engine features enhanced reliability, fuel economy and greater service life compared to its predecessors produced in the former Soviet Union. The engine has a modular design. The nine modules can be replaced in the field, which dramatically reduces costs and accelerates repair and maintenance. The engine has an electronic-hydromechanical control system.
The TV7-117S engine has been offered to power the newest Russian turboprop aircraft such as Ilyushin Il-112 and Ilyushin Il-114. In addition, Klimov developed the TV7-117V turboshaft to power rotary-wing aircraft, such as the Mil Mi-38, and marine drives for high-speed boats and industrial electric power plants. The TV7-117 engine family is produced by Klimov JSC, Chernishov JSC and the Baranov JSC and Aerosila propellers for TV7-117S variants.
