The HAL Corporation of India has received two AL-55I turbojet engines delivered by Russia's United Engine Corporation (UEC) for the final stage of certification tests of the Indian HJT-36 combat trainer plane. This was announced by the press service of UEC today.
UEC said in a statement that it has completed work to increase the resource performance of the two delivered engines to 300 hours. During the work on the project, the life of the AL-55I engine design was gradually increased. The engines have worked on the stands for more than 5000 hours and passed more than 4,500 cycles of equivalent-cyclic tests. The installed service life guarantees the reliable operation of the engine for a specified time.
"After successful acceptance tests at the test stand in the presence of the customer's representative, the engines have been shipped to HAL Corporation. The establishment of the HJT-36 training aircraft is in the final stage of flight certification testing, which must confirm the compliance of the HJT-36 aircraft with the requirements of the Indian Air Force. Engines with increased service life will be used to complete this stage. There are also plans to increase the resource indicators for 16 AL-55I engines already supplied to HAL Corporation earlier. Additionally, significant work has already been done to organize the licensed production of AL-55I engines at the enterprises of HAL Corporation," said Yuri Shmotin, Deputy Director General and the General Designer of the UDC. AL-55I is a two-circuit turbojet engine, developed for the Indian Corporation HAL for HJT-36 training aircraft.
The engine has a number of advantages, its modular design, in particular, provides high manufacturability and low cost of operation, and modern digital control system - piloting safety and ease of maintenance. The engine has a traction index at a maximum mode of 1760 kgf. To date, the life of the AL-55I engine design is 1200 hours.
In February this year, as part of the international aerospace exhibition Aero India, the engine was successfully launched by an Indian training aircraft HJT-36 during demonstration flights.
The AL-55I engine will be presented at the stand of the United Engine Corporation at the MAKS-2021 airshow, which will be held from July 20 to 25 in Zhukovsky near Moscow.
HJT-36 is is a subsonic intermediate jet trainer aircraft is design and developed by Aircraft Research and Design Centre (ARDC) and built by Hindustan Aeronautics Limited (HAL) for the Indian Air Force and the Indian Navy. The intermediate jet trainer, known in India as the Sitara ('Star').
