progressive increase in capabilities is gud isn't it ......;)
I agree with you but you are doubling that no. 200 current to 400. Is'nt too much. Arm force already in process to induct large no of ALH, LUH and LCH I know they r middle weight category but some how they filling the no. which arm force required

EXCLUSIVE: The Proposed Indian Multirole Helicopter (IMRH) Detailed

The Indian Multi-Role Helicopter (IMRH), which should hopefully soon begin development with the selection of an international technology partner, finally has a set of final specs (they underwent a change last year). The image you see above is the first diagrammatic representation of the helicopter from official material being prepared for documents that will follow up the invitations for Expressions of Interest (EoI) sent out last year.
HAL has proposed that the platform needs to have an all-up weight of 13 metric tons, a maximum speed of 275-km/h and a service ceiling of 22,000 ft. The Indian military wants the helicopter to have a payload capacity of 3,500-kg and range of 500-km at sea level. The IMRH platform is to sport a five-blade composite main rotor with a four-bladed composite tail rotor, twin turboshaft engines with dual full authority digital engine controls. The powerplants would be required to have a 30-minute dry-run capable transmission system. All IMRHs will have glass cockpits -- using equipment from Halbit Systems, DARE and Samtel.
The bid is stuck, however, at the EoI stage, with four companies wondering what is happening. Companies that have responded to HAL’s invitation include Eurocopter (EC725 Caracal), Sikorsky (S-92A), Agusta-Westland (AW101) and Mil (Mi-17-IV).

Officially the IMRH mission spectrum includes troop movement, high-altitude air maintenance, offshore operations, heliborne and amphibious assault operations, anti-submarine warfare and anti-surface warfare. An armed gunship version is also expected to be concurrently developed. Other proposed variants include civil transport, VVIP transport, and air-ambulance.

regards sir ,

but any no. of alh luh ... won't be able to fill the role of medium lift helis....

and i said 300-350 not 400 ...... even lowest difference of no. (ie 50) makes a big difference !!!!
 
Guys ...

Just wanted to let you all know that Hari Nair has joined BR and is active in lch thread...and he's providing some real good and serious inputs about LCH (no jingo BS)... so if you have any questions ...do post it...the more the better...the guy seems to be treasure trove of knowledge...
 
India to buy 139 military helicopters from Russia

Moscow - India is planning to purchase some 139 military helicopters from Russia with a total value of up to 1.5 billion euros (1.9 billion dollars), Moscow daily Vedomosti reported Monday.

The newspaper cited Rosoboronexport, Russia's state arms exporter, as confirming the deal.

The two countries had already signed a deal in 2008 for the delivery of 80 Mil Mi-17 helicopters, which can be used in both transport and combat roles. The Indian government has however ordered a further 59 aircraft.

The Indian government has in recent years been in the process of updating its military hardware, and has already ordered two aircraft carriers and a nuclear submarine from Moscow.
 
Scientists working on smart material for ALH

Scientists at the Indian Institute of Science and public sector aircraft maker Hindustan Aeronautics Limited (HAL) are working on a way to reduce vibrations in the advanced light helicopter (ALH) using smart materials.

The project, funded by HAL, aims to build an “active trailing edge flap” and a “controller” that will make the flap, mounted on the aircraft’s rotor blades, respond in such a way to the aircraft’s vibrations that they will be reduced.

Reducing vibrations, apart from making the flight more comfortable for passengers, puts less strain on the aircraft’s structures, making them durable.HAL’s Rotary Wing Research and Development Centre is collaborating with IISc’s department of aerospace on the Rs 6 crore effort.

IISc’s scientists said there are five different parts of the project. “Some of them are at the fabrication and prototype stage, at both the institute and HAL, following which there will be wind tunnel and other tests. Others need more work. An initial prototype, to demonstrate the concept, will be ready in two years. After that, to actually build an ALH-ready system that can get certification will take till 2010.”
The controller is a box, with hardware and software in it, taking inputs from all over the helicopter on its natural vibrations. It will then send out instructions to actuators, little motors, that will drive the flap.

“We use piezoelectric materials (substances that change structure in response to an electric current) to build the actuators. Mounted on the rotor blades, the flap will try to imperceptibly twist the blades in such a way as to oppose the deflection caused by the natural vibration of the helicopter and so reduce it, even as the aircraft is in full flight,” the scientists explained. The technique is called independent blade control. In theory, these materials, either “surface mounted” or “embedded” in the rotor blades, can twist the blades by up to two degrees, reducing vibrations by up to 60 per cent. There are hurdles, of course. Helicopters are subject to unsteady aerodynamics as they use their rotors for both lift and thrust (moving forward).

They also work in environments of high (electronic and/or electrical) noise. The software programmes in the controller must then be robust enough to handle measurements made in such environments.

Further, much work was needed on the operational capability of the smart materials themselves – on their fatigue tolerance, for instance. Finally, repeated flight tests will be required to show that the system was both effective and safe.

Similar work is going on in other parts of the world and some scientists are trying variations of the independent blade control.
For instance, a research team in Canada published a paper in the Journal of Intelligent Material Systems and Structures last year, on a “smart spring” they are building, for “active vibration control of helicopter blades”.

They found, the researchers C Yong et al say, the piezoelectric actuator based control had its limitations and the smart spring was a way to do better.

Work at the IISc-HAL combine too may evolve as such projects often do. Success will mean not only a superior aircraft, more attractive to overseas buyers, but also 100 per cent indigenous know-how in this area — far more important in the long run.
 
Army Transport Helicopters Deal - Boeing Offers CH-47 Chinook Heavy-lift Helicopters

300px-Inbound_Choppers_in_Afghanistan_2008.jpg


Boeing, a leading American defense and aerospace company, has offered India the CH-47 Chinook heavy lift helicopters in response to a Ministry of Defence Request-for-Proposal (RFP) for 15 transport helicopters for the Indian Army.

Confirming exclusively to India Defence (Indian Defense News and Networking | India Defence), Dr. Vivek Lall, Vice President, Boeing Defense, Space and Security, India said:

"We also responded to the RFP for 15 transport helicopters with our CH-47 Chinook. We believe the CH-47 Chinook offers India a powerful workhorse helicopter, as capable in supporting the Indian Army in rugged high-altitude outposts, as it will help build India’s infrastructure and bringing life-saving relief supplies to victims of natural disasters. Chinooks will offer India heavy-lift and high-altitude transportation for multitude of military, humanitarian, rescue, disaster relief, fire-fighting and nation-building missions in all climates and conditions and altitudes. They are ideally suited for India’s vast distances, austere environments and high altitudes."
-- Dr. Vivek Lall

The Boeing CH-47 Chinook is a twin-engine, tandem rotor heavy-lift helicopter. Its top speed of 170 knots (196 mph, 315 km/h) was faster than contemporary utility and attack helicopters of the 1960s. It is one of the few aircraft of that era that is still in production and front line service with over 1,179 built to date.

Its primary roles include troop movement, artillery emplacement and battlefield resupply. It has a wide loading ramp at the rear of the fuselage and three external-cargo hooks. Chinooks have been sold to 16 nations with the US Army and the Royal Air Force being the largest users and it has seen action in the Vietnam war, Iran-Iraq war, Falklands war and is currently in operation in Iraq and Afghanistan.

Initial steps to induct a very suitable helicopter. It will be an invaluable asset to the air-lift capabilities in the NE. :tup:
 
Is anything known if the Mi 26 attended the trials now and what the new specs/capabilities of it are? If the Mi is upgraded and sparepart supply is secured, I would prefer it, simply because this is about heavy lift capability in first place!
The Chinook is of course a good helicopter, but falls short in this regard and actually I am surprised that not the CH 53E, or it's future version K are in the final stage of this competition.
Btw, any news about the LUH competition and the outcome of the trials? Only the EC Fennec and the Ka 226 are left, so it shouldn't take too long to decide the winner right?

The Mi-26 is a heavy weight lifting champion. That is all. But that chopper has many down-sides. Without going in to too many details, the Chinook has far better attributes, chiefly better manoueverability, smaller heli-pad requirements and far better serviceability.
The Mi-26 can lift a Chinook (as depicted by pictures). But is that a prime requirement of the IAF? The Chinook can lift a howitzer, field gun or light truck, which is what it will be called upon to do in the North-East. There will not be any requirement to heli-lift tanks! The terrain in the NE does not allow large helipads to be constructed so where will the Mi-26 operate from; very few locations.
One more point, the Chinook has greater survivability to hits.

This discussions Mi-26 v/s Chinook has a parallel in the An-124 v/s C-17 debate.

I know the advantages of the Chinook, but those advantages that you point out here has nothing to do with the competition imo. Landing on small heli pads, lifting howitzers and so on is nothing that we need the Chinook for, because we already have 100s of Mi 8/17 to do that. This competition is for real heavy lifting and by the fact that we will replace older Mi 26, the replacemeant should offer comparable lift capabilities. That's why I see CH 53s, or if possible new Mi 26 as the best option.
That lifting howitzer argument makes no sense anyway if you keep in mind that even the first order of M777 howitzers was for over 100, but this helicopter competition is only for 15 helicopters!

Btw, imo the C17 deal was purely done for political reasons! There is simply no way that this is about actual increase of capabilities, but that's a different story and we can talk about per PN if you want.
