MOSCOW, RUSSIA — The Russian Federal Agency for Air Transport (Rosaviatsiya) has given its approval for the engine that will power the revamped Ilyushin Il-114-300 aircraft - while the manufacturer is currently developing a derivative test engine that will be used in future turboprop plane models.

The Klimov TV7-117ST-01 engine is combined with a six-bladed propellor intended for the Il-114-300, an improved variant of the current Ilyushin Il-114 turboprop aircraft.

Rostec, Russia's state-owned technology company, said the engine, which yields an increased thrust rate and enhanced fuel efficiency, has successfully passed a series of tests. Its performance has been checked and analyzed under all environmental conditions.

After this incident, the Il-114-300 program was hampered in 2021 when the prototype for a new military transport aircraft, the Il-112V, crashed due to an in-flight engine fire during a test flight.

The Il-114-300 program was temporarily halted as the two aircraft utilized similar engines from the same manufacturer.

Klimov, the original manufacturer, is currently developing another variant of the engine, designated the TV7-117ST-02 - which has been designed specifically for use in the UZGA TVRS-44 regional aircraft.

The TVRS-44 is a 40- to 50-seat turboprop aircraft which will replace aging regional aircraft from the Soviet era, such as the Antonov An-24 and Yakovlev Yak-40, as well as some western-made aircraft, including early Bombardier Dash 8s and ATR 42s. The TVRS-44's engine is based on the TV7-117ST-01 but will have an electric starting system, plus a revised oil system and high-speed alternator.

According to Rostec, Klimov will produce four pre-production powerplants for Il-114-300, of which two will be designed for summer and another pair to be pre-produced for "preliminary aircraft testing" before the end of the year.

The Russian government had been encouraging the country's aerospace industry to adopt more indigenous components in their product designs long before the imposition of foreign sanctions against the Russian Federation - but these pressures had only increased under the strict and widespread international trade restrictions that were unilaterally imposed by the United States and European Union in response to Russia's ongoing military operations in Ukraine.
