First media report..


India test flies light combat chopper successfully
http://economictimes.indiatimes.com/new ... 743118.cms


BANGALORE: India has successfully flight tested a prototype of the Light Combat Helicopter (LCH), designed and developed by the state-run Hindustan
Aeronautics Ltd (HAL), a top official said Tuesday.

"The maiden test flight of the LCH Monday evening was successfully. Though it was a short haul lasting about 20 minutes, the performance was good," HAL chairman and managing director Ashok Nayak told IANS.

The 5.5-tonne attack copter is a derivative version of HAL's flagship product Advanced Light Helicopter (ALH), christened Dhruv.

"We will be conducting more test flights to evaluate its various parameters at different altitudes and conditions. We are looking at reducing the weight considerably for better manoeuvrability," Nayak said.

Made of lightweight composites, the LCH can operate at high altitudes up to 6,000 metres or 18,000 feet.

The prototype was flown with Shakti engine, developed by HAL in partnership with Turbomeca, the French manufacturer of aero engines for global aerospace majors.

"Plans to launch the flight trials of LCH have been going on over the last couple of months but got delayed due to reassessment of its various functions and flight control systems," a official of the company's copter division said.

HAL plans to hard-sell about 150-175 units of the LCH to the Indian defence services, mainly Indian Air Force (IAF) and Indian Army, which already operates the military version of Dhruv for various functions.

Senior officials of the company's helicopter division and IAF were present at the HAL airport to witness the test fight.

The LCH will be equipped with a helmet-mounted targeting system, electronic warfare systems and advanced weapons systems.

The LCH will incorporate a number of stealth features and crash-worthy landing gear for better survivability. It will have a narrow fuselage, with two crew stations.

FWIW HAL is media shy these days, more than secretive.

p.s. where's his favourite multi-coloured fonts ? :mrgreen:

They better be. Any delays / failures in future (God forbid) will only embarass them, a la LCA. Some of us BRFites are champs at that!

awesome vishnu ! thanks a lot !

some comments :

> can't quite place the helmet, looks similar to the ELBIT HMS. not quite like the top-owl.

> FLIR ball is a mock-up right now ?

> z is army registration IIRC. (added later : wrong info, ignore.)

> lastly but most importantly, they need to re-do the eye, add a little red may be. right now it looks a decidedly gandhian tiger.

Great pic.However,it shows what I find to be one crucial difference when seen in comparison with attack helos worldwide,in that the second cockpit is located much lower than in rival helos.The view of the pilot/gunner to either beam is excellent,but the rear crew member's view straight on leaves a lot to be desired.Whether this is going to be a handicap only the testing regime will tell.Otherwise the shaping of the chin/fuselage (look at the similar approach of the Chinese attack helo) indicates RCS/stealth features incorporated.Now fo a swift testing programme and induction into service.

LCH looks good. However the cockpit is a bit too much exposed. Would have preferred a higher back seat and less glass on the cockpit like this one has. Maybe they needed to put this much glass due to the weight. Hopefully the final version will address these issues.

Great effort by HAL.

Looks like the same amount of glass as that on an AH-64 Apache or a Eurocopter Tiger

Less glass = less visibility. So add some more metal in the way and then people will come out and say that LCH has less visibility than AH-64 or Eurocopter Tiger. You can't win 'em all.

Does the cockpit have bulletproof glass... also I wonder if it wud have been better to have a Comanche style tail to complement the stealth features

Compared to other Heli's, LCH has a "boxy" structure, i.e. fuselage is made of few straight panels, joined together sharp angles.

Is this a stealth feature? Like Ships have now boxy structures covering pretty much everything? But Helo with a huge fan up there and stealth dont necessarily make sense?

Any gyan? For better armor?

nukavarapu wrote:I was under impression for sometime that the rear wheel is just gonna stick out straight, but looking at the pics, the rear wheel has a pneumatic lever to pull it up, but I don't see any significant space on the tail to pull the rear wheel in. Is it just going to stick to the tail on bottom side and be outside horizantally during flight compared to vertical position while landing or hovering??? Any gyan wud be greatly appreciated !!!


IMO, 'pneumatic lever' is a shock-dampener for impacts with landing surface, akin to the ones in the front. When landing wheel impacts landing surface, it swivels about the pivot transferring energy to the dampener, effectively cushioning energy transfer to the fuselage. Its going to stick-out all the time, like it appears in the pictures of first flight.
