HAL Indian Multirole Helicopter (IMRH) : Updates & Discussions

The ICG also has a requirement for a 10-tonne class multi-role helicopter. However, a deal with Airbus for 14 helicopters fell through after coming close to conclusion. HAL is developing the Indian Multi-Role Helicopter (IMRH) in the 12-tonne class for the Armed Forces. Officials said the Coast Guard is in talks with HAL for developing a modified variant of the IMRH to meet its requirements.

Indian Coast Guard also interested in HAL IMRH for its requirement

HAL's IMRH seems to be the largest helicopter in its category. Most other helicopters are coming at a maximum length of around 20m but IMRH goes around ~25m.

That's because of the rotor length requirement came from high altitude performance. Cabin size would be normal i imagine.

Safran Helicopter Engines and Hindustan Aeronautics Limited (HAL) have decided to set up their new joint venture company in Bangalore, India. It will be dedicated to the design, development, production, sales and support of helicopter engines, with first objective to build the most adequate propulsion solution for the Indian Ministry of Defence’s (MoD) future 13-ton IMRH (Indian Multi-Role Helicopter) and its naval version DBMRH (Deck Based Multi-Role Helicopter). This joint venture will be India’s first engine design and manufacturing in house.

This decision was achieved thanks to a dynamic common work cycle between the two companies, following a Memorandum of Understanding (MoU) signed on 8th July 2022 and an agreement on workshare reached between the two partners during Aero India 2023.

The collaboration the Indian and French Aerospace majors is clearly supporting the development of the aerospace strategic roadmap between the two countries while once again endorsing the Indian Government’s vision of “Atmanirbhar Bharat” - particularly in defence technologies. Safran Helicopter Engines and HAL see this joint venture as a natural further step in their robust, well balanced and growing relationship.

Mr. Cedric Goubet, Safran Helicopter Engines CEO, said: “We at Safran Helicopter Engines are truly elated to partner with HAL and India to craft this new turboshaft engine joint venture set to address the Indian market and also future export opportunities. It marks a turning point in not only the longstanding relationship between our two companies but also between India and France. Together we will remain fully dedicated to our customers in India, proud to designing and producing new efficient helicopter engines.”

Mr. C.B. Ananthkrishnan, CMD, HAL said: “Safran Helicopter Engines has been our valued partner for several decades. We both have embarked on a new journey, leveraging HAL’s experience in manufacturing of more than 15 types of aircraft and helicopter engines and Safran Helicopter Engines’ expertise in desiging turboshaft engines. The objective is to co-develop and co-produce turboshaft engines in India - with immediate focus on IMRH and DBMRH. This partnership will engage and harness the Indian Defence manufacturing ecosystem towards realising Atmanirbhar Bharat vision of our Honble PM”.

Safran Helicopter Engines and HAL already have multiple successful partnerships on helicopter powerplants, including the Shakti engine, which powers HAL-produced helicopters, comprising the Dhruv, Rudra and the Light Combat Helicopter (LCH Prachand). More than 500 Shakti engines have already been produced. The new joint venture further extends the sphere of current cooperation and explores opportunities for strategic business collaboration that leverage the complementary talents and capabilities of the two aviation firms.

Through HE-MRO joint venture in Goa, Safran Helicopter Engines and HAL will also provide MRO (Maintenance, Repair and Overhaul) services for TM333 and Shakti engines in the service of Indian Armed Forces.
 
The project sanction for the Indian Multi-Role Helicopter (IMRH), being developed by Hindustan Aeronautics Ltd. (HAL), is expected within this financial year, defence sources said.

Meanwhile, Safran Helicopter Engines and HAL have decided to set up their new joint venture company in Bengaluru, which will be dedicated to the “design, development, production, sales and support of helicopter engines” with the focus first on the IMRH, the French company announced.

The IAF operates a very large Mi-17 fleet — Mi-17, Mi-17 1V and Mi-17 V5. It is the workhorse of the IAF’s helicopter fleet. Between 2008 and 2013, India contracted 151 Mi-17V5s, the last of which were delivered in February 2016. In all, the IAF operates a wide mix of around 500 rotary platforms, which include around 90 Mi-17s, over 130 Mi-17V5s, over 70 ALH, including the weaponised variant, 22 AH-64E Apache attack helicopters, one squadron of Mi-35 attack helicopters and 15 CH-47F Chinook heavy lift helicopters, in addition to the LCH currently being inducted. The oldest lot of Mi-17s are expected to be phased out from 2028 onwards.

HAL is looking at benchmarking the proposed IMRH against its contemporary helicopters namely Russian Mi-17, Sikorsky S-92, AgustaWestland AW-101, NHIndustries NH-90 and Eurocopter EC-725 and intends to target the global helicopter market. The intended roles of the IMRH are to support air assault, air transport, combat logistics, combat search and rescue and casualty evacuation as well as be employed for VVIP duties, HAL officials had stated earlier.

The HAL plans to produce more than 1,000 helicopters in the range of three tonnes to 15 tonnes, with a total business of over ₹4 lakh crores over a period of 20 years. In February, HAL inaugurated its new helicopter factory at Tumakuru in Karnataka, which is the largest helicopter manufacturing facility in India and will initially produce the Light Utility Helicopter (LUH). Initially, this factory will produce around 30 helicopters per year which can be enhanced to 60 and then 90 per year in a phased manner, HAL had stated.

The Navy has projected a requirement of over 100 MRH and an earlier global tender for 123 MRH has been dropped. The Navy is currently in the process of inducting 24 MH-60R MRH procured under a $2.2-billion deal with Lockheed Martin signed in February 2020 with deliveries expected to be completed by 2025.

So, IMRH engine (HAL-Safran JV) will be clean sheet. I didnt expect this !.

I feel like in the long run it will be a more impactful partnership than AMCA engine or GE414 partnership.

In the 3,000 shp market it will have to compete with GE T901. It was developed under Improved Turbine Engine Program (ITEP). It is the replacement engine for Apache and Blackhawk. Also, for the US Army Future Attack Reconnaissance Aircraft (FARA) program.

Design and performance goals

In addition to 3,000-shp output, the targets for AATE were a 25% reduction in fuel consumption (less than 0.347 lb/(hp⋅h), 211 g/kWh), a 65% improvement in power to weight (more than 6.5 hp/lb, 10.7 kW/kg), a 20% improvement in design life (more than 6000 hours and 15000 cycles), a 35% reduction in production (less than $650k per engine) and maintenance cost, and a 15% reduction in product development cost. The 3,000-shp goal for AATE is a 50% increase over the most powerful T700-701D variant, but would also require upgrades to gearbox, transmission, rotor blades, and tail rotor.

Both the ATEC and GE designs can start without an auxiliary power unit (APU), using the battery alone. The UH-60 and AH-64 are currently equipped with Honeywell GTCP 36-150 APUs.

Using ITEP, the combat radius is projected to increase by 500 km (270 nmi). The hot and high service ceiling will be increased from 4,000 to 6,000 ft (1,200 to 1,800 m) at 95 °F (35 °C). Performance targets have been determined in part by operations in Afghanistan and Iraq, as well as growing airframe weights.

If they could active these goal, then there is nothing like it. Is it too much to ask? :)

IMO, joining the US side always comes with some major perks. Those who are using BlackHawk and Apache will continue to do so and replace with what US beings to the table. As was seen in case of Aussi they replaced all of their Tigers with Apache instead of the upgrading them.

So competing with US specially in rotor segment is very tough when they themselves have got so many major players. But we can Target the markets which do not need weapons with golden price tag.

The AMCA engine is much more important, but yeah, this one is right up there. It's enough to take care of our medium lift requirements while being competitive with the West. Huge deal all these tech transfers.
 
HAL is very happy to show concepts as of now. Trying to run way too many things together, typical psu habit when pressed. I hope they have enough resources to be put into this. They will never get sales from showing concept to their target market. Rather make the existing heli more versatile, add more weaponry & important gadgets at affordable pricing, which is the main usp for them.

What is the status of the joint venture to design and develop helicopter engines with Safran?
The JV will become operational next month, and production of engines is expected to begin in four years. These engines will be for the Indian multi-role helicopter (IMRH) and its deck-based version. There is a requirement for around 400 such helicopters. We are looking at basing the Safran-HAL JV at our new Tumakuru facility, which is the largest helicopter manufacturing facility in the country. We can manufacture up to 90 helicopters in Tumakuru every year, a mix of LCH, light utility helicopters and IMRH. With the JV based there, Tumakuru will become one big complex for helicopters and associated equipment. Safran and HAL will have a 50:50 work-share. IMRH could go into production with the new engine by 2031. The timelines are tight, but the good part is that we are already manufacturing the Shakti engine for the advanced light helicopter with technology transfer from Safran.
If its a cleansheet engine how can it start production in 4 years? Maybe he meant prototype production.
