Hindustan Aeronautics Limited (HAL) is making significant strides in its development of the Indian Multi-Role Helicopter (IMRH), a 13-ton medium-lift helicopter designed to meet the diverse needs of India's armed forces and civil aviation sector. HAL aims to debut the first Ground Test Vehicle and prototype by 2027, showcasing India's growing capabilities in aerospace technology.
The IMRH, first unveiled at Aero India 2023, is envisioned as a versatile, indigenous alternative to foreign rotorcraft. HAL has been refining the IMRH's design, focusing on enhanced aerodynamics, structural safety, and aesthetics to ensure it meets global standards in helicopter manufacturing.
One of the most significant developments in the IMRH program is the integration of the Aravalli engine, a new high-power propulsion system developed in partnership with SAFHAL Helicopter Engines Pvt. Ltd. This collaboration marks a major step towards engine self-reliance for India's aerospace industry.
While initial IMRH prototypes will utilize an existing Safran engine, the Aravalli engine is intended to be the primary powerplant for the helicopter, offering improved fuel efficiency, performance, and reliability.
The IMRH is designed for a wide range of missions, including troop transport, logistics support, medical evacuation, and search and rescue. Its 13-ton lift capacity makes it particularly well-suited for operations in challenging environments like the Himalayan region.
The IMRH is expected to replace aging foreign helicopters currently in service with the Indian Armed Forces, contributing to India's "Atmanirbhar Bharat" (self-reliant India) initiative.
Beyond domestic requirements, HAL also sees the IMRH as a competitive player in the global medium-lift helicopter market. Building on the success of its Dhruv Advanced Light Helicopter (ALH) in the export market, HAL believes the IMRH, especially with the indigenous Aravalli engine, will attract international customers seeking high-performance helicopters at competitive prices.
The IMRH program is currently focused on completing the first prototype and Ground Test Vehicle by 2027. Following rigorous testing and design optimization, full production is expected to commence in the following years, with the Aravalli engine being integrated in later production batches.
