The Indian aerospace sector is gaining international attention. Recently, Indian helicopter fighter jets demonstrated incredible performance at various airshows, demonstrating the strength of the aircraft’s manufacturing and supply.

With the introduction of the IMRH, HAL will expand its Helicopter Product offerings from 03 Ton to 13 Ton weight class, as well as address India’s requirement to replace the ageing Mi-17 helicopters, which are due for replacement progressively beginning in 2028. HAL intends to target the global helicopter market by benchmarking the proposed IMRH against its current helicopters, which include the Mi-17, S-92, AW-101, NH-90, and EC-725.

The Rotory wing R and D center played an important role in the Indian aerospace sector. The HAL Journey of building helicopters began in 1965 with the introduction of the Chetak, and by 1970, with the assistance of France Aérospatiale as a licensee, the Cheetah helicopter was built.

Further, in 2002, It introduced the ALH Dhru, and in 2013, it introduced the ALH Rudra, and in 2017, it launched the Light Combat Helicopter, and in 2019, it launched the Light Utility Helicopter, and now it is planning to build the 13 tonne weighing multirole helicopter. which is set to replace the air force’s MI-17 helicopter

HAL’s rotory wings design and research Centre in Bangalore designed and developed the helicopter. In the beginning, three prototypes will be created: one for the structural test specimen and one for the ground test vehicle. Certifications are expected 7 years after the project is sanctioned.

HAL’s Rotory wings R & D center in Bangalore designed and developed the helicopter. In the beginning, three prototypes will be created: one for the structural test specimen and one for the ground test vehicle. Certifications are expected 7 years after the project is sanctioned.

HAL has already constructed a mechanism system, an air frame, blades, and a slew of other component-designed 3D concept parts that are fitted into the concept mhttps://jetlinemarvel.net/indian-air-force-jets-5000-sorties-72-hours-western-front/odel. It is a Utility and Armed variant designed for unrivalled performance at high altitude for the Indian air force and army.

The navalized version will also have a longer range and a greater payload capacity. HAL estimates that over 314 rotocraft of the same class will be required to replace the existing Mil Mi-17 helicopters in service in India.

The helicopter is expected to have a maximum take-off weight of up to 14.2 tonnes and a crew of 24 to 36 people in various configurations. The helicopter will have a two-bladed tail rotor and a five-bladed main rotor with a diameter of 21.2 metres. MRH will be made up of 75% domestic content but will be powered by an imported 2000kW turboshaft engine. At sea level, the payload capacity will be 4 tonnes, and at 13,000 feet, it will be 1.5 tonnes. The aircraft will have two weapons wings with four hard points for up to 1,600 kilograms of armament. two inboard for a total loading capacity of 500 kg and two outboard for a total loading capacity of 300 kg. It can reach a top speed of 260 km/h.

The aircraft has completed the preliminary design phase and is expected to be approved for further development in early 2022. The first flight is scheduled for four years after the development project began, with the introduction scheduled for 2028-29.

The HAL is currently releasing a global tender for the component requirements for the new Multipurpose helicopter. Keeping in mind that the government encourages and invites local suppliers to take on the design and construction of HAL components.

HAL has already constructed the rotor system’s component mechanism. It has undergone virtual stress analysis with the aid of software, and it has a transmission system or gearbox that weighs one tonne and is built in bulk using die casting techniques.

HAL is looking for a special engine for the helicopter that can generate 2000 kw of power. As a result, once the project begins, the design suitability in the air frame will be updated to OEM during the prototypes.

Typically, few medium helicopters do not have retractable landing gear built into the airframe, but the HAL already has retractable and non-retractable try cycle landing gears.

The Tricycle has fixed crashworthy wheel landing gear, passive steering, and a nose wheel lock, as well as a hydraulic wheel brake with a parking brake.

It has two electric power generators and an auxiliary power unit that can restart the power supply in the event of an emergency.  Even HAL claims that the battery will provide backup power for the helicopter’s other functions during the 30-minute flight during emergency.

A broad overview of proposed airborne equipment and sensors was presented, emphasising the opportunities for private sector participation in the proposed IMRH programme, which will pave the way for India’s self-reliance, in line with the Government of India’s initiative of Aatmanirbhar Bharat Abhiyaan.

There are already a few medium lift helicopters in service around the world, such as the Russian MI17, which has a capacity of 13 tonnes, the Sikorsky S-92, which has a capacity of 12.9 tonnes, the August Westland 101, which has a capacity of 15.6 tonnes, the NH90, which has a capacity of 10.6 tonnes, and the EC 725 eurocopter, which has a capacity of 11.2 tonnes. Indian multirole will be one of the future sources of additional support for Indian defence.

Taking into account the ministry’s approval of the project. The first flight is expected to take place within four years, and the operation clearance is valid for six years. If the project begins in 2022, HAL will likely phase out legacy MLH by 2029.

Furthermore, this helicopter can be used for a variety of purposes, including cargo transport, ground vehicle transport, VIP transport, and many others. Once this helicopter is inducted, HAL will become a major Aerospace market key player in the Asia region, building helicopters ranging in size from 3 to 13 tonnes. This will be another victory for the Indian aviation industry.
