• Hindustan Aeronautics Limited (HAL) revolutionizing its manufacturing process for the Light Utility Helicopter (LUH) to meet the growing demand from the Indian Army and Indian Air Force (IAF)

• LUH, a 3-tonne class, new-generation helicopter, is designed to replace the aging Cheetah and Chetak helicopters

• The Armed Forces plans to retire its fleet of around 400 Chetak and Cheetah from 2027 onwards and is planning to replace them with the modern LUH

Bengaluru, December 4. Hindustan Aeronautics Limited (HAL) is revolutionizing its manufacturing process for the Light Utility Helicopter (LUH) to meet the growing demand from the Indian Army and Indian Air Force (IAF). This new approach aims to accelerate production and bolster India’s domestic aerospace manufacturing sector.

The LUH, a 3-tonne class, new-generation helicopter, is designed to replace the aging Cheetah and Chetak helicopters. With the Indian armed forces requiring nearly 400 LUHs, HAL is optimizing its production to reach a potential peak capacity of 30 units per year at its Tumakuru facility.

HAL’s strategy involves a shift from traditional in-house manufacturing to a decentralized model. This involves outsourcing the production of modular components to Indian suppliers and Micro, Small, and Medium Enterprises (MSMEs). These partners will manufacture individual modules, which will then be transported to HAL’s Tumakuru facility for final assembly.

This collaborative approach offers several advantages:

Increased Production Capacity: By focusing on final assembly, HAL can streamline its processes and potentially increase production rates to meet the urgent demand for LUHs.

Boost to Domestic Aerospace Industry: Empowering Indian suppliers and MSMEs to participate in LUH production fosters a robust domestic aerospace ecosystem. This initiative aligns with India’s “Make in India” initiative, promoting self-reliance in defence manufacturing.

Cost and Time Efficiency: Leveraging the expertise and infrastructure of outsourcing partners can potentially reduce manufacturing costs and lead times.

Enhanced Quality Control: While decentralizing component production, HAL retains control over the final assembly process, ensuring the quality and integrity of the finished helicopter.

To ensure precise and efficient final assembly, HAL will utilize advanced coupling jigs at its Tumakuru facility. This technology will facilitate the seamless integration of the various modules produced by its partners.

This strategic shift in production not only addresses the immediate need for LUHs but also lays the foundation for a more resilient and self-reliant Indian aerospace industry. By involving a network of domestic suppliers, HAL is contributing to the growth and development of the sector, while ensuring the Indian armed forces receive a modern and capable helicopter to fulfil their operational requirements.

The Army has a deficiency of the light helicopters. There are around 190 units of these helicopters of which at least 25 are in Maintenance Repair and Operations (MRO)at HAL.

This is down from 246 units in count. In fact, around 134 of the helicopters are about 30 to 50 years old and are nearing the end of its Total Technical Life (TTL). Also, Air Force operates 120 of these helicopters including the 18 of newer Cheetal variant. However, the first batch of the older helicopters has been retired already

About HAL-LUH

The HAL Light Utility Helicopter (LUH) is a 3-tonne class highly agile new generation light helicopter. According to HAL, it possesses a cruise speed of 235 km/h, maximum speed of 260 km/h, service ceiling of up to 6.5 km, a range of 350 km with maximum take-off weight of 3.12 tonne and an empty weight of 1.91 tonne.

The LUH will be capable of accommodating a maximum of two pilots and six passengers, all of which shall be seated on crash-worthy seats; externally, it is capable of carrying cargoes of up to 1 tonne under-slung.

LUH with glass cockpit will be able to undertake various missions, including emergency medical services (EMS), troop transport, utility, search and rescue (S&R), VVIP Transport, aerial reconnaissance and surveillance missions.

LUH is equipped with Smart Cockpit Display System (Glass Cockpit), state-of-the-art HUMS (Health & Usage Monitoring System).
