Flight tests beckon for Il-114 powerplant

Russia's United Engine Corporation is preparing for a series of flight tests with the powerplant set to equip the new Ilyushin Il-114-300.

The Klimov TV7-117ST turboprop has been fitted to an Ilyushin Il-76 heavy transport testbed – normally powered by four jet engines.

It has formed part of the static display at the MAKS air show in Moscow.

United Engine says the powerplant is "currently being prepared for flight tests" at the Gromov institute in the Zhukovsky region of the Russian capital.

The powerplant is a modification of the TV7-117SM and will typically be able to deliver up to 3,000hp during take-off.

United Engine says the powerplant has been undergoing bench tests since September last year, and is currently being subjected to endurance assessments.

The manufacturer says an automatic control system will cover the "entire" powerplant, including the Aerosila propeller.

United Aircraft is aiming to restart production of the Il-114 in order to meet demand for short-haul and regional capacity. The TV7-117ST engine is also intended to power the Ilyushin Il-112V military transport.
