HAL and Safran Join Forces to Build India’s First High-Power Helicopter Engine
India is taking a major step towards building its own high-power helicopter engines. Hindustan Aeronautics Limited (HAL) and France’s Safran Helicopter Engines have signed an agreement to jointly develop ‘Aravalli’, a new 3,500–4,000 shaft horsepower engine in India.The engine is being developed for HAL’s 13-tonne Indian Multi-Role Helicopter (IMRH) and its naval variant, the Deck-Based Multi-Role Helicopter (DBMRH).The programme is being undertaken through SAFHAL Helicopter Engines Pvt Ltd, a 50:50 joint venture between HAL and Safran. It will cover not just development but also lifecycle support for the engine.From Licensed Production to Homegrown TechnologyWhat makes the Aravalli programme particularly significant is the shift it represents.For years, India has relied heavily on foreign technology and licensed production for several critical aerospace systems. This project aims to move beyond assembly and production towards joint design and development of a high-power helicopter engine in India. Indian engineers will work alongside Safran specialists, gaining experience in engine design, testing and certification.The programme will give HAL access to crucial technologies involving the high-pressure compressor, power turbine, fuel and oil systems, accessory gearbox and external engine systems. The knowledge and intellectual property developed during the programme could also become a stepping stone towards future indigenous aero-engine projects.Built for India’s Most Challenging MissionsThe Aravalli engine will be designed to operate in the demanding environments where India’s next-generation helicopters are expected to fly. The IMRH is being developed as a versatile 13-tonne helicopter for the Indian Armed Forces, while the approximately 12.5-tonne DBMRH is intended for naval operations.But the possibilities could extend beyond military applications. The helicopter platforms could potentially serve roles including offshore transportation, utility missions and VVIP transport, opening the door to future civil aerospace applications.Why ‘Aravalli’ MattersThe engine will be manufactured at Tumakuru, Karnataka, creating opportunities for Indian companies involved in advanced manufacturing, precision machining, castings and raw materials. The programme is also expected to strengthen India’s domestic Maintenance, Repair and Overhaul (MRO) ecosystem.The design development of the Aravalli engine is expected to be completed by 2032–33, subject to the required defence approvals for the helicopter programmes. Named after the ancient Aravalli mountain range, the engine carries an ambitious message: India wants to climb higher in one of aerospace’s most difficult technologies.If successful, Aravalli could be more than an engine for two helicopters. It could become the foundation for India’s next generation of indigenous rotorcraft propulsion.
