The troubled Child of Hindustan Aeronautics (HAL), HJT-36 Sitara Intermediate Jet Trainer (IJT) after being grounded for over 3 years had commenced spin testing following extensive work to rectify previous issues with this area of the flight envelope, last year and initial results seem to be promising for the HAL to believe that the aircraft could enter production by 2024-25 if the Spin trial completion data is accepted by the Indian Air Force (IAF).
idrw.org has been informed that the HJT-36 had demonstrated satisfactory initial spin behavior after it went through an extensive redesign of the rear fuselage and the rudder, that has further spin trials delayed due to the CCP Virus situation in the country for few weeks but, HAL plans to conclude all spin trials by mid of 2022. Once the Spin trials parameters are demonstrated, aircraft will be offered to the IAF for User trials that hopefully will be completed by 2023 that also includes weapons trials.
NPO Saturn AL-55 engines from Russia are being currently used to power-Limited Series Production jets and HAL is keen to offer its own Hindustan Turbo Fan Engine (HTFE-25) engine but that might not happen for the first batch of the HJT-36 that will go into production by 2024-25, but likely on subsequent batches. HAL also plans to certify the HTFE-25 (25kN) engine by 2024 that includes flight certification so that it can be offered as a more powerful alternative to the imported AL-55 (17.3kN) engine when HJT-36 is cleared for production.
