The HAL Light Combat Helicopter (LCH) is a multirole combat helicopter being developed in India by Hindustan Aeronautics Limited (HAL) for use by the Indian Air Force and the Indian Army.

Development

In 2006, HAL announced its plans to build a LCH. Funds for the design and development of the LCH to meet the requirements of the Indian Army and the Indian Air Force were sanctioned in October 2006.

The LCH is a derivative of the HAL Dhruv, which was inducted into the Indian armed forces. Using a successful and proven helicopter as the base platform is expected to conserve the project costs for the LCH, which is pegged at 8.76 billion (US$166.4 million).[1] The Indian Air Force is to acquire 65 LCHs and Indian Army is to acquire 114 LCHs.[2]

The LCH was expected to be ready for the Initial Operational Clearance (IOC) by December 2010 with the Final Operational Clearance (FOC) in 2011. However, the revised timeframes hold that the 5.5-tonne LCH should be ready for induction into IAF by 2012-2013.[3]

The first prototype of LCH completed its first ground run on 4 February 2010.[4] HAL has a firm order to deliver 65 LCH to the IAF and 114 to the Army.[5] HAL has performed the maiden flight of its indigenously designed and developed LCH on 29 March 2010. The first LCH Technology Demonstrator (TD-1) flew a 20 minute flight from HAL's Helicopter Complex, Bangalore. It carried out low speed, low altitude checks on the systems on-board. The crew reported that the performance of the helicopter and systems were satisfactory.[6][7]

Second LCH prototype (TD-2) improved upon TD-1 by incorporating substantial weight reductions. Ashok Nayak, chairman of HAL stated that it has exceeded the human and payload requirements mandated by IAF for development.[8][9][10] TD-2 is the first attack helicopter in the world to get a digital camouflage.[11]

Design

The LCH incorporates stealth features, ability to perform night operations and crash landing gear for high survivability. The LCH will have a narrow fuselage, with two crew stations.[12]

The LCH is being designed to fit into an anti-infantry and anti-armour role and will be able to operate at high altitudes (16,300 feet).[13] The helicopter is powered by the HAL/Turbomeca Shakti turboshaft engine. The helicopter will be equipped with helmet-mounted targeting systems, electronic warfare systems and advanced weapons systems.

In 2006, HAL selected the M621 cannon incorporated in a Nexter THL 20 turret for the gun armament of the helicopter, operated by a helmet mounted sight.[14][15] Three prototypes will be built. The second version will be fitted with weaponry before its test flight. The Indian Air Force will be provided with the third prototype for user trials.[16]

The LCH is to have a glass cockpit with multifunction displays, a target acquisition and designation system with FLIR, Laser rangefinder and laser designator. Weapons will be aimed with a helmet mounted sight and there will be an electronic warfare suite with radar warning receiver, laser warning receiver and a missile approach warning system.

The helicopter is to be fitted with a data link for network-centric operations facilitating the transfer of mission data to the other airborne platforms and ground stations operating in the network, facilitating force multiplication.[17]

With these features, the LCH is expected to play a major role in air defence against slow moving aerial targets, destruction of enemy air defence operations, escort to special heliborne operations, support of combat search and rescue operations, anti-tank role and scout duties.[17]

The two pilots in the LCH sit one behind the other, compared to side-by-side in the Dhruv. All the flight controls, the hydraulics and the fuel system had to be redesigned for the LCH. The LCH’s stealth features also necessitated redesigning the fuselage.

Operational history

The third test flight of the LCH was successfully made on 23 May 2010 and it fulfilled the desired parameters and also paves the way for further testing with weapons. The second prototype, which has been weaponized with more sub-systems was unveiled at Aero India 2011 in February 2011. Light Combat Helicopter TD-2 achieved its first flight on June 28, 2011.[18] Over 20 test flights have been conducted to check various flight parameters. Two more prototypes are under construction to speed up its induction into the Indian Air Force in 2012.

Sri lanka ordered 20 LCH from Hal.
