Hindustan Aeronautics Ltd has carried out maiden run of core of the 25 kN thrust turbofan engine being developed indigenously in Bengaluru, India.

Dubbed the Hindustan Turbo Fan Engine (HTFE-25), the engine is designed to power basic, intermediate and advanced trainer aircraft.

The engine can also be used on business jets and five ton weight class aircraft in single engine configuration and on aircraft of up to nine ton weight class with twin engine configuration.

The program began in 2013 and HAL hopes to complete the development by 2018. The program was first unveiled at the Aero India 2015, where a engine mock up was revealed.


In the first phase of the program, the design of the full engine and manufacture and testing of the technology demonstrator of the core engine will be demonstrated. In the subsequent phases the manufacture and testing of the full engine will follow.

The HFFE-25 is a low bypass twin spool, mixed flow turbofan engine with a length of  1.73 m, diameter of 0.590 m. The 350 kg engine is controlled by full authority digital engine control (FADEC).

The engine could power the delayed IJT-36 Kiran Intermediate Jet Trainer aircraft being developed by HAL.
