The Federal Air Transport Agency of the Russian Federation (Rosaviatsiya) has authorized the operation of the engine TV7-117ST-01 for the IL-114-300 at altitudes up to 6 thousand meters and at speeds of up to 550 kilometers per hour. This permission is one of the stages for flight tests, the external communications department of the United Engine Corporation said.
By the end of the year, six power units will be provided for flight tests, and a decision on the start of serial production will be made based on their results.
“At present, ODK-Klimov is preparing for flight tests of TV7-117ST-01 as part of the Il-114-300 aircraft. In addition, we are preparing two more backup engines in a certified type design, and four more engines will be provided by the end of the year for flight tests of the aircraft,” said Vsevolod Eliseev, General Designer of ODK-Klimov.
Earlier, in December 2022, Rosaviatsiya issued a type certificate for the engine TV7-117ST-01. This is a turboprop engine with a free turbine, which has a higher takeoff power (3100 hp) and the best fuel efficiency in its class. The engine is controlled by a FADEC type electronic system (BARK-65SM) and works in tandem with the new AB112-114 propeller, which has an increased thrust of 4 tons.
