The Chairman of Hindustan Aeronautics Limited (HAL), Devasri Kutti Sunil, revealed that HAL will initially lease several SJ-100 regional airliners from Russia to get acquainted with the maintenance, reliability, and ecosystem of the aircraft. Simultaneously, it will build infrastructure for construction.
Assembly in India will start in three years.
HAL estimates a total requirement of 200 SJ-100 aircraft and a larger number of Il-114-300 turboprop regional airliners.
HAL plans to set up engine assembly and a repair facility for the TV7-117ST-01 turboprop engine that powers the Il-114-300. It may also consider local manufacture of engine parts and the engine itself.
Russia is open to HAL’s aspirations, says Ekaterina Rukhlova, Head of the Civil Aviation Engine Sales Department at UEC.
The Il-114-300 has completed flight certification tests with TV7-117ST-01 engines. Engine prototypes have flown almost 3,000 hours during more than 400 flights.
The TV7-117ST-01 belongs to a family of engines built with the TV7-117SM as the base.
The TV7-117ST-01 has a takeoff power of up to 3,100 hp and, in comparison with the base engine (TV7-117SM), differs in design features and higher power in takeoff and cruise modes. The power plant includes a new high-thrust AV-112-114 propeller and a new ACS using a combined modernized engine control unit and a BARK-65SM propeller, providing a thrust of up to 4 tons.
