Relying entirely on the Internal company funds, Hindustan Aeronautics Limited (HAL) plans to certify its Hindustan Turbo Fan Engine (HTFE-25) ’25’ signifying the thrust of the engine to be 25 kN by 2025 by testing it onboard company-owned Hawk Mk. 132 Advanced trainer aircraft designated as “Hawk-I”. has been informed from industrial sources close that, the flight certification process will start from 2024 and should be completed in the next few years.

HTFE-25 will not be replacing the present Rolls-Royce Turbomeca Adour Mk. 951 turbofan engines that are powering the Hawk Mk. 132 AJT fleet of the IAF, but it has been proposed to be used as a powerplant on the Hindustan Aeronautics (HAL) HJT-36 Sitara Intermediate Jet Trainer (IJT) that presently is undergoing spin testing following extensive changes to its tail and rear fuselage.

Two Core engine Prototypes of the HTFE-25 engines have undergone 100 percent max speed and have carried out nearly 500 runs on the engine ground testbed. HAL plans to start testing the fan stage of the engine soon. HAL last year had proposed the development of HTFE-40, which is a reheated derivative version of the HTFE-25 with an afterburner section to be used as engine replacement on the Jaguar deep penetration ground attack aircraft fleet, for which HAL had sought funding from the Indian Air Force (IAF).
