Indian Multi Role Helicopter (IMRH)

Lol hence the wait. It seems it has permiated into all of us. I believe we had to wait for a catch up from the out side. 7000 years ago these guys were making anti gravity aircraft and energy weapons so im not bothered if they forgot an old gas burner, which won't take time other then a show of lethargy on parts unkown.

Read what you said and ask yourself if you understood anything, because I didn't understand what you said. Whatever you want to say, say clearly. Otherwise, you have to write and you alone have to read it.

What that means is we delibrately wait for newer countries to catch up all the while acting like we dont know and have specs and designs ready in classified. Please let me know if you need to know more.

We don't. Only congress does. You should have assassinated Nehru and Indira Gandhi. Then India would have been much better off. Nehru was a conspirator and not a leader. Pradesh Congress committees of 15 provinces had elected Vallabh Patel by 12 votes while other 3 didn't vote. Nehru, however, threatened to destroy India if not made PM and thus usurped power. The other cowards were good for nothing and did nothing to eliminate Nehru. Then Shastri was killed by Soviets and installed Indira as PM. Indira's policy of extreme socialism is because of her allegiance to Russia. In 1967 Israel war, she unwarrantedly, sided with Arabs and drew hostility from NATO.
When you have foreign agents working, how do you expect India to improve? The word we applies only if the people chose these things voluntarily. It was only after BJP came to power, did people realise Indianness. But the Arab oil power is constraining BJP from taking drastic steps and hence is acting very shrewdly in an indirect manner. With BJP in power, "We" will not wait

Three months after the unveiling of HAL's full-scale 12-ton multirole helicopter (IMRH) mock up at Aero India, the program is moving forward. HAL has floated bids for the twin turboshaft powerplant that will drive the monster copter.

Safran-Turbomeca (talks have begun), Rolls Royce, GE & UAC/Klimov are likely to be part of any prospective contest. In addition, HAL has set out to have the transmission system reviewed and possibly redesigned by the engine house that enters discussions.

HAL has also invited interest in a tech-design partnership to consult on the rotor design, blade folding system and landing gear system on the IMRH.

HAL will be at the Paris Air Show this month, where they're likely to open discussions with vendors on a variety of systems the IMRH will need.

French defence giant Safran keen to supply engines to HAL for indigenous helicopter


Hindustan Aeronautics is looking for 3,000 shp class twin engines for the rotorcraft

MUMBAI, OCTOBER 13:
Safran Helicopter Engines, manufacturer of gas-turbine engines for both civil and military helicopters, is developing a new family of high-power engines called Aneto. The French manufacturer is looking to supply its engines to Hindustan Aeronautics Limited (HAL), which had floated a global request for information (RFI) for the purchase of engines to power its home-made multi-role helicopter.

Developed as part of the Safran’s research and development roadmap, the Aneto family of engines features several models covering 2,500-3,000 shp (shaft horsepower) power range, known as heavy helicopter engines.

HAL’s RFI had stipulated that the State-owned firm is looking for 3,000shp-class twin engines and is aiming to fast-track development of its indigenous helicopter.

HAL is engaged in the design and development of rotary wing aircraft with state-of-the-art technologies. The company intends to purchase the engine under a technology-transfer agreement.

HAL aims to develop the 12tonne-class Indian Multi-Role Helicopter (IMRH), which will be designed to offer a service ceiling of around 20,000 feet, 3,500-kg payload with a seating capacity of 24. The aircraft will be able to assist in combat search-and-rescue, tactical troop transport, casualty evacuation, sling-load transportation, anti-surface operations and off-shore operations, among other activities.

The proposed IMRH is to be powered by twin engines and equipped with an automatic flight-control system. Initially, the indigenous helicopters will be aimed at the Indian Air Force, while a naval variant also is on the cards.

The new Aneto engines by Safran boast of an exceptional power-to-volume ratio, offering 25 per cent more power compared with existing engines of the same volume. The company has said this will provide increased capabilities, especially for offshore, search-and-rescue or military transport missions.

HAL’s RFI for the “supply of suitable turbo shaft engine for IMRH programme” has also evinced interest from other foreign OEMs. Sources indicated that the RFI relates to turbo shaft engines, assistance with development of a blade-folding system and external reviews of the 12-tonne rotorcraft’s landing gear and transmission.

Design and development of the landing gear will also be undertaken by HAL’s Rotary Wing Research Design Centre. The duration of the design review period is six years.

No indegeneous helicopter engine developement effort on this front?

 

[LOYALBHARTI8]

There is no money allocated to the development of this kind of engine. You can't expect everything from NDA. It's gonna take some time but eventually its gonna happen. NDA is trying to fill in the blanks and keeping the future in mind to Make in India.

First we have to make smaller engines.

 

[Kunal Biswas]

Prototypes are always meant to work with highest imported content, The gud news is HAL is actually making some progress with IMRH to disuses about engines on first place ..

===============

The route will be same for the new IMRH engine ..

I guess everyone forgot about HTSE-1200

HTSE targets 3tons category. DOesnot match for IMRH.

Some one said that HAL is not working on a Turboshaft, the answer was for that.

 

[Kunal Biswas]

Well, I should put this up too ..

The specs are impressive, I presume this will go for LCH and may be Dhruv MK5 in near future ..

[Rahul Singh]

HTSE-1200 in x3 configuration like in AW101 could make HTSE 1200 standard turboshaft abroad all HAL Choppers. Smart move if taken up.

I think HAL should either consider developing IMRH as a 3 engine helicopter or developing a uprated version of HTSE. Say HTSE-2500.

Published on Oct 3, 2017

Safran unveiled its brand-new Aneto high-power engine family. Designed for the new super-medium and heavy helicopter market, the Aneto range will deliver from 2500 to over 3000 shp.

Its seems HAL want the best engines for license production ..

I think HAL is trading carefully. It wants to have a proven Turboshaft for IMRH and also have a peek into high rated Turboshaft, considering it is looking for ToT of selected engine.

Basing new IMRH on an unproven engine is anyway going to be unusual approach and very risky both technically and commercially. However, once IMRH matures HAL might start rolling out MK-XX versions with an appropriate version of HTSE. Maybe this is the reason why HAL is not taking 3 engine approach. Other being inherent maintenance issues that 3 engine configuration will have over an 2 engine version.

Let me remind you. This program is still in TD stage.

For IMRH, Tender asks about the possibility for future collaboration to make a high altitude friendly version of the engine.

With regards to latter part of your post, you should read my previous post on this same page, Post no #169

Tender asks about the possibility for future collaboration to make a high altitude friendly version of the engine.

 

[Kunal Biswas]

I always have stated three-four engine design, here a example ..

 

[Kshithij]

HTSE targets 3tons category. DOesnot match for IMRH.

Helicopters are generally run on twin engines. Single engine is possible like in LUH but will be less in demand. So, 1200kWx2 can carry 6tons.

HTSE-1200 in x3 configuration like in AW101 could make HTSE 1200 standard turboshaft abroad all HAL Choppers. Smart move if taken up.

I think HAL should either consider developing IMRH as a 3 engine helicopter or developing a uprated version of HTSE. Say HTSE-2500.

3 engine is rare and even then the 12ton won't be lifted by 3600kW. It will need 4500kW+ to be able to operate in Ladakh and Siachen. So, a new engine uprated at 2400kW is needed
