    My Analysis of IMRH design:-


    If you look at the intakes, the overall design is similar to Super Puma series (which also has passing resemblance to Mi-8/17 series). Other contemporary Helos like NH-90 & EH-101 has layout like our own ALH & LUH. This makes me wonder whether there is some French input in the design. Interesting to note that the latest layout is different from earlier drawings which resembled enlarged ALH.

    The cabin volume is similar to Mi-17 but the cabin is slightly longer and higher. IMRH is definitely bigger than Sea King, NH-90, S-92, Super Puma and smaller than Mi-38 and largely in same category as Mi-17.

    The MTOW of 12.5tons and Payload of 3.5 tons should not be considered as final word as these figures are always indicative. The payload will depend on the engines that are selected. As IMRH is intended to go upto 6500m (with some reasonable payload) therefore I think that its MTOW will be equivalent to or more than Mi-17V5.

    The HAL clip on IMRH seems to indicate a Naval version which has the capability to fold the rotor blades. This means that the rotor assembly would be different than ALH (LUH?) as this folding mechanism could not be integrated on ALH rotor assembly and HAL is trying out folding blades.


    The engines that can be used are T700, Makila, PW127 etc. Lets see how things pan out.

    Aero India 2017: HAL displays mock-up of multirole helicopter

    Hindustan Aeronautics Limited (HAL) has displayed a full-scale mock-up of its Indian Multirole Helicopter (IMRH) proposition at Aero India 2017.

    The twin engine platform is in its preliminary design phase and two versions are planned in the transport configuration. The troop configuration will have a seating for 24, while the VIP transport version will seat 18 with a cabin volume of 23 cubic metres.

    A HAL company representative told Jane's , "HAL intends to fast-track development of this platform and we plan to release an RFI for the 3,000-shp-class twin engines before July this year. Initially it will be aimed at the Indian Air Force and even Indian Army requirements, while a naval variant is also planned."

    The 12.5 tonne IMRH will have a service ceiling of 21,320 ft and a payload of 3,500 kg. The maximum speed for the platform is expected to be 230 km/h with a maximum range of 500 km - this will be extended to 800 km with external fuel tanks.

    HAL chief on an interview said deatiled design will take 18-20 months more. So, we can assume first flight by 2020.

    So it is safe to assume that it could be inducted by 2025-27 if things work out well. Not too shabby. It's not like we are suffering from a chronic shortage of medium helis unlike other things airforce. 150 spanking new Mi17 should work fine till then.

    Cabin dimentions look pretty neat and above all as HAL chief said, there will be user specific versions so no more 3500 kilo as final payload.

    Unit Cost must be well below that of Mi-17.

    India Aims to Export Its Home Grown Multi-Role Helicopter to 40 Countries
    Government owned firm HAL has unveiled its twin engine 12 ton class multi-role helicopter at Aero India 2017 where more than 900 delegates including 25 foreign delegates from seven countries are participating.

    Worked too fast this time instead of unveiling plan before, first flight in 2-3 years? :)

    India-made multi-role choppers to match Russian Mi-17s

    India is pursuing plans to build its own multi-role helicopters that could be made available to the three services in the next 6 years.

    If all goes as per the plans of Hindustan Aeronautics Limited, the first prototype of the helicopter could be out by 2020. A senior HAL official said the programme was on track and a priority for the state-owned firm.

    Here’s all you need to know about the Indian multi-role helicopter (IMRH) project:

    Competition for Mi-17 choppers

    The IMRH is expected to compete with Russian Mi-17 choppers in both Indian and foreign markets. HAL says the platform could have a huge market as nearly 40 air forces across the world operate Mi-17 type helicopters. The Mi-17 is the mainstay of the Indian Air Force’s transport fleet.

    Types of missions

    HAL officials say the IMRH will be capable of carrying out a wider variety of missions than the Mi-17. The indigenous helicopter, which is currently in design stage, could be used for transporting troops, conducting assault operations, air maintenance and anti-submarine warfare among other roles.

    Specifications of proposed India-made multi-role choppers
    • Weight class: 12.5 tonne
    • Engines: 2
    • Payload: 3,500kg
    • Passengers: 24
    • Service ceiling: Over 20,000 feet
    Indigenous platform

    The HAL is seeking to build the helicopter without any foreign help. However, HAL sources said the engines for the IMRH could be sourced from a foreign military contractor. HAL has estimated a requirement for 350 to 400 choppers but the number could be revised depending on market projections.

    Indian helicopter fleet

    The IMRH will join a wide variety of helicopters in the Indian fleet ranging from Mi-17V5, Dhruv advanced light helicopter, Ka-226T (yet to be built) to Apache attack helicopters and Chinook heavy-lift choppers whose induction will begin in about 2 years.

    Do we have a domestic engine program to power IMRH?

    Nope. HAL is likely to issue RFI for IMRH engine later this year. Safran is most likely bidder.
