 AERDC is a R&D wing of Design Complex, HAL playing a vital role in the design and development of Gas Turbine Engines in India. It has successfully designed, developed, produced and type certified aero engines (PTAE & GTSU) which are in operation with the defence services. Patents have also been issued by Patent Office, Govt. of India for these two engines.

The Centre started functioning in the year 1960 as a hub of engine research and development with the aim of achieving self reliance in design and development of Gas Turbine Engines and Test Beds in a climate of growing professional competence.

The Hindustan Jet Engine or HJE-2500 project was the first jet engine design and development project in the country taken up by the Centre. A prototype engine was successfully developed and proven on the test bed in 1965 and was proposed for the HJT -16 aircraft. The centre also designed and type certified a piston engine and other engine accessories including a pneumatic starter and hydraulic pump in its early days. The centre also has the unique distinction of being the only design house which has developed test beds for both Western as well as Russian origin engines.

Leveraging on this experience end to end services right from preliminary design to the final product manufacturing and testing are offered. AERDC has fledged its wings and is continuously improvising to meet customer requirements. With the advent of new technologies the division has equipped itself with high end design, analysis and manufacturing tools to meet the challenges of the future.
