It is high time that HAL in ALH should look for A Fenestron (or fantail, sometimes called "fan-in-fin") design



Fenestron - Wikipedia, the free encyclopedia

So that ALH should be evolving into new design.
It adds to weight and cost without adding much to the performance. It's a good thing to have on civilian helicopters reducing the noise and vibration, but of not much use on a military helicopter. A 100 Kgs in redesigned tail is a 100Kgs off payload.

Just first step to go for stealth ALH design in future.

R&D would not just stop with one design.

Its costly ,maintenance prone,bulky ,high drag VS low tail noise ,safety from accidental contacts . The disadvantage outweighs the advantage

may be that's why most of choppers still go with contemporary designs

This was projected in past but due to some reasons probably simplicity, the design is changed ..

LOH is now LUH, Some details >>









HAL LOH is supposed to have it, The technology is there. Maybe LCH MkII will have it as well.

Kunal sir we need Mist Mounted Sight for this.

to be used to see above tree top





I read the post on BR where the person working on LCH said that it is quite difficult to make Mist Mounted system because of vibration etc. But they will make it when development of helicopter is complete.

Sir, It would be a great tool in reconnaissance, Given that the optics at Mist Mounted can be larger in size compare to the one mounted on nose ..

The simmering debate about ownership of attack helicopters reached a precipitation point during March last year with the Defence Minister announcing that the ownership of future inductions of attack helicopters will vest with the Army. Meanwhile, HAL's Rudra has received its initial operational clearance and is projected as the first armed helicopter being produced indigenously in India for a wide range of missions, including reconnaissance, anti-tank warfare and close air support. Development of the Rudra variant was authorised in December 1998 and a prototype made its first flight in August 2007. It completed 20mm turreted gun firing trials in September 2011 as well as Mistral air-to-air missiles and 70mm rockets tests in November 2011. Mistral is an infrared homing missile which is capable of striking targets within a range of 6.5 km. The maximum take-off weight of the helicopter is 5,500 kg and it can carry a payload of 2,600 kg. The Rudra can be fitted with up to eight Helina (Helicopter Launched Nag) anti-tank guided missiles, four MBDA Mistral short-range air-to-air missiles or four rocket pods for 68mm/70mm rockets. HAL was committed to deliver 76 Rudra ALH Mk-IV helicopters for the Indian Army and the IAF, and has handed over the first platform to the Indian Army in February 2013. The IAF is looking forward to the Rudra for high altitude operations, as no country makes attack helicopters for high altitude operations as foreseeable in the Indian context.

There is an agreed transfer of technology plan with HAL for Ardiden1 (Shakti) in four phases. In phase 1, we provide the complete engine to HAL and in the following phases HAL will gradually manufacture. In the ultimate phase, HAL will manufacture 70 per cent of the engine, with Turbomeca providing 30 per cent of smaller kits." On where the program was currently, Philippe said "it is between phase 1 and 2" and that the ultimate phase would depend on the helicopter development program of HAL.
