On August 30, 2024, Hindustan Aeronautics Limited (HAL) and SAFHAL Helicopter Engines Pvt. Ltd. (SAFHAL) formalized their collaboration by signing a contract to develop the Aravalli engine, intended for two new helicopter platforms: the Indian Multi-Role Helicopter (IMRH) and the Deck-Based Multi-Role Helicopter (DBMRH). This engine represents a major advancement in helicopter engine technology, offering enhanced power, performance, and versatility. The project is crucial in replacing the aging fleet of Mil Mi-17 helicopters currently used by the Indian Army.Follow Army Recognition on Google News at this link

SAFHAL is a joint venture between Safran Helicopter Engines and HAL, focused on the design, development, manufacturing, and support of next-generation helicopter engines in India. Established in 2023, this venture aligns with the Indian government’s “Atmanirbhar Bharat” vision, aiming to achieve self-reliance in aerospace and defense technologies.
The IMRH, designed by HAL, is a 13-ton multi-role helicopter tailored to meet the diverse operational needs of the Indian Armed Forces. It is intended for missions such as troop transport, combat search and rescue, and medical evacuation, requiring a robust and reliable powerplant capable of efficient performance in various demanding conditions.
Technically, the IMRH will be powered by two turboshaft engines, each producing approximately 2,415 horsepower. These engines, controlled by a FADEC (Full Authority Digital Engine Control) system, will drive a five-blade main rotor and a four-blade tail rotor. The helicopter is expected to achieve a maximum speed of around 275 km/h, with an operational ceiling of 21,500 feet and a range of approximately 805 kilometers. It will have a payload capacity of about 4,500 kg.
The IMRH’s design extensively incorporates composite materials to ensure a lightweight yet durable structure. The cockpit is designed to offer excellent visibility, and the helicopter is equipped with retractable landing gear to enhance ground mobility. Measuring about 16 meters in length and 5.25 meters in height, the IMRH is designed to be both high-performing and versatile.
The DBMRH, on the other hand, is a 12.5-ton variant optimized for naval operations, designed to operate from ships and capable of missions such as anti-submarine warfare and search and rescue at sea. This version is specifically optimized to withstand corrosive maritime environments and the variable flight conditions encountered at sea.
The Aravalli engine, named after the mountain range in India, is the result of advanced technology jointly developed by HAL and SAFHAL. This next-generation engine is designed to provide high power and optimal efficiency, essential for the demanding missions these helicopters are intended to perform. The engine is also envisioned for future civilian applications, such as offshore transport, utility missions, or VIP transport, after specific adaptations.
The collaboration between HAL and Safran Helicopter Engines through SAFHAL highlights the commitment of both companies to developing cutting-edge technologies. This partnership aims to strengthen India’s technological capabilities and promote self-reliance in the crucial sector of helicopter engine technology.
