LCH delayed by an year
Business Standard, 10th Feb 09
Visitors to Aero India 2009, being held in Bangalore from 11th to 15th February 09, who hoped to catch a first-ever glimpse of Indias high-tech Light Combat Helicopter (LCH), will go back disappointed. Hindustan Aeronautics Limited (HAL) has told Business Standard that design glitches --- including extra weight and delays in manufacturing the tooling on which the LCH will be fabricated --- have pushed back the first flight by up to a year.
Some consolation will be afforded to enthusiasts of indigenous production from the first display flights of a black leopard-painted prototype of the armed Dhruv Advanced Light Helicopter. Called the Weapons Systems Integrated Dhruv (WSI Dhruv) this is the machine on which the LCHs armaments and sensors are being perfected, even as designers struggle to pare down the extra 250 kilos that have come up on the LCH.
An extra 250 kilos may not seem much on a 5.5 ton helicopter, but it really is a serious problem, explains HALs helicopter design chief, N Seshadri. At altitudes of 6000 metres (almost 20,000 feet), which the LCH must operate at, the air is so thin that it can only carry a weapons payload of about 350-500 kg. If the helicopter ends up 250 kg heavier than planned, its high altitude firepower will be dramatically reduced.
Being built on the basic design of the Dhruv ALH, the LCH is currently HALs most prestigious project. Many of its components, including the engine, crucial moving parts like the rotor, and the instrumentation of the LCH have already been tested on the Dhruv. Armaments and sensors are taking shape on the WSI-Dhruv. With much of this already done, HAL had planned to fly its first LCH prototype by December 08; a second prototype was to be readied in the first half of this year. But that timeline has turned out to be too ambitious.
One reason is that the LCH is technologically far more complex than the Dhruv. The Dhruv is a utility helicopter, designed for simple tasks like reconnaissance, casualty evacuation and for conveying small teams of up to 7 soldiers. In contrast, the LCH is an attack helicopter, a flying weapons platform built purely for combat. It must fly and fight by day and by night, bringing down missile, rocket and cannon fire on dangerous enemy targets like tanks. To avoid detection by radars and by individuals it must fly almost at ground level; its crew needs bulletproofing against ground fire. It must have sophisticated electronics to confuse enemy radars.
The private sector company that has designed the LCHs fuselaeg, Plexion Technologies, is working overtime to cut down the extra 250 kg. Meanwhile HAL is trying to convince the air force to accept the first prototype with some extra weight, so that flight tests can begin even as Plexion slims down the LCH.
There are some delays also in selecting the weapons systems that the LCH will carry. The air-to-air missile, which will be bought from abroad, has not been selected. The LCH was to be fitted with the DRDOs Nag anti-tank missile, but the services want a missile that can hit tanks at 7 kilometers, compared with the 4 km range of the Nag. So while the DRDO works on a longer-range version of the Nag (called the HELINA, or Helicopter-mounted Nag), a foreign missile will have to be bought as an interim solution.

AeroIndia 2009: Combat Helicopter prototype will fly in 2009: HAL design chief news
11 February 2009
Bengaluru: The prototype of India's Light Combat Helicopter (LCH) is presently being built and will fly by the end of the year, said HAL Rotor Wing Research & Development Centre (RWRDC) Design Chief Dr Prasad Sampath. He was speaking on 'Development of Helicopters in India ・An Overview' today, at the Aero India 2009 International Seminar on 'Aerospace ・Perspectives and Trends in Technologies', being held in Bengaluru from 9 to 12 February.
He said that the cockpit and fuselage design for LCH was complete, and the mock up trials were over last year. All dynamic systems of the LCH are identical to HAL's Advanced Light Helicopter (ALH) and only the fuselage and the landing gear have been designed afresh for the fighting version of the chopper.
After considerable design analysis, the weight class of the LCH has been maintained the same as the ALH, and therefore there should be little difficulty in the prototype successfully flying, he said.
The HAL RWRDC has also developed a helicopter simulator called the Hats-Off Simulator, which can be fitted with all the different cockpit mockups of the different choppers that HAL makes, he said.

Anyway, there seems to be no new info on the LCH. Think they're becoming more media-savvy and doing the tests in secret, and only announcing them when they tweak the product and succeed, like everyone else in the world. open societies and accountability have their drawbacks.
Don't think the shchinese dude really noticed that the WZ-10 is a copy of the Agusta A129 Mangusta which the Chinese evaluated it back in the 80's.
Our friend's link to a WZ-10
The Agusta A129 Mangusta
How typical. Let them have a few minutes to write down technical details, open up the hood for a few pics and they'll produce it. They may not know how to use it or even what it is.
I popped across to Shenzhen, where i got a TV remote replicated. The supposed engineer put components together in the same way my busted remote was put together. He had no idea what the finished product was supposed to be or do, because i'd just given him the chip-board, and not the remote casing.

chinese people are damm proud of their technology ,their R&D program ,should be replaced by C&P , copy and paste .and they critise us for our indeginious program
whole chinnese air force is based on copied desgins from russia , so sad , couldnt develop aircraft on their own so why not copy ,

This is good, I am following Indian media for long, they are more corrupt then Indian politician. Just for the sake of more TRP they can say whatever they want, doesn't matter weather its is for the country or against.
I guess, its an good idea for ISI to pay them some bucks and they will talk what they want. It is more effective then training guys for terrorism.
$$$$$$ what they are looking for only. No responsibility as a media.
This much freedom of press is not even in Germany, UK or in USA no where, forget China.
Can't you see the differences or do you need someone to list them out?
- front landing gear
- fuselage shape
- turbine enclosure, shapewise
- nose mounted sensor
- # of tail rotor blades, Z-10 (4) A129 (2)
Seriously, when you criticize something atleast try to be rational.

it's still a copy even if WZ-10 is a helicopter with rotor blades, that's the law

India will shortly test fly the indigenously designed and built Light Combat Helicopter (LCH), which will augment the IAF’s fleet of small and highly manoeuvrable rotary flying machines.
A ‘baby’ of the Bangalore-headquartered defence PSU Hindustan Aeronautics Limited (HAL), the first prototype of LCH is expected to take to the skies between December 26 and December 29, a senior HAL official told PTI here on Monday.
HAL has already bagged a firm order to deliver 65 LCH to the IAF and 114 to the Army, company sources said.
Unlike HAL’s Advanced Light Helicopter (ALH) “Dhruv” which has been described as broad and bloated, the LCH is very, very sleek. The new light chopper is currently undergoing functional tests, and is expected to be ready for ground run by December 24.
“It (LCH) is quite different from ALH in terms of configuration and structure,” the official closely associated with the project, said on condition of anonymity.
HAL hopes to obtain certification for LCH in 2012-13, and the delivery of the machines is expected from 2014-15.
LCH would also have a weaponised version, similar to ALH.
“There will be rocket pods, a machine gun and also an air-to-air missiles in the combat version of LCH. But in the first prototype all these features will not be there,” the official said.
HAL has also started design of a light observation helicopter (LOH) which would eventually replace the ageing fleet of Cheetah and Chetak helicopters which have been in service since 1978. “We have got about 600 of them (Cheetah and Chetak) in service now. They are reaching the end of their technical life as they have flown 60,000 hours or more,” he said.
