Bengaluru: The Light Combat Helicopter (LCH) is at striking distance from being inducted into the Services. The designers and test crew at the Hindustan Aeronautics Ltd (LTD) vouch for the chopper’s might with four prototypes having completed the pre-induction trials as mandated by the users – the Indian Air Force (IAF) and Indian Army.

During a recent visit to the Rotary Wing Research and Design Centre (RWRDC) of HAL, Onmanorama was briefed by the officials about the future flightpath of the combat chopper programme.

The Defence Acquisition Council (DAC) had cleared the proposal to induct initial batch of 15 LCHs. Notwithstanding the final orders to formally come, HAL had gone ahead and began the process of manufacturing the limited series production (LSP) platforms.

HAL officials are confident of Light Combat Helicopter becoming one of the most resourceful and potent chopper for high-altitude missions.

Of the 15 LSPs, 10 are for the IAF and the remaining five for the Indian Army. There’s an additional projection of 65 LCHs for the IAF and 97 for the Indian Army. The LSP of LCHs was launched in August 2017 by Arun Jaitley, when he was holding the additional portfolio of Defence.

Post completion of all trials, HAL officials now say that they are confident of LCH becoming one of the most resourceful and potent chopper for high-altitude missions. The programme has already got the Initial Operational Clearance (IOC).

The officials said that during firing trials, the chopper performed excellently meeting accuracy requirements.

“This is the first attack helicopter with us which has aerial combat capabilities. A moving UAV can be taken on easily with an air-to-air missile or with the front gun. This was a capability gap the Services had and LCH will fill it now,” an official said.

LCH is the only attack helicopter in the world capable of landing and take-off with considerable payload at high altitudes.

When asked about the ‘many firsts’ the chopper offers to the user, the official said: “LCH has such an efficient navigation system that enables to deliver the weapons with accuracy measured in milliradians. Be it day or night, you can rely on LCH auto-pilot, while the optical devices ensure you pick up the target at ease”.

Last month, LCH had successfully fired the Mistral-2 ATAM (air-to-air-missile) hitting a moving aerial target, during the weapon trials held at the Integrated Test Range at Chandipur in Odisha.

LCH is the only attack helicopter in the world capable of landing and take-off with considerable payload at high altitudes such as the Siachen glacier.

The need for a dedicated combat helicopter, which can operate effectively at high altitudes with considerable payload in terms of weapons and ammunition, was an immediate fall out of Kargil War in 1999. Subsequently, the requirement for a dedicated combat helicopter was provided by IAF in August 2003.

At present, Indian armed services have dedicated weapon platforms of Russian origin which have limitations for operations at the high altitudes and LCH is expected to fit in that role.

7 LSPs getting ready

Seven LSP platforms are at various stages of manufacturing at the assembly hangars of HAL now.

“This is the new thought-process as we are sure to get the orders and our idea is to deliver the choppers at the earliest. We are confident to hand over the first LCH well within the contractual schedule,” the official claimed.

He said LCH with the versatile features built in for combat missions has tremendous export capability.

“We have the capability to customize and integrate systems and weapons as per the customer requirement. HAL has now obtained the NOC (no objection certificate) from the Ministry of Defence to explore the possibilities to export LCH to Malaysia, Myanmar, Thailand, Vietnam, Angola, Egypt, Indonesia, Ecuador and Nigeria,” the official added.

The designers have many learnt many lessons from the Advanced Light Helicopter (ALH) programme of HAL that came handy for LCH project as well. Today the ALH Dhruvs are being used widely by Indian Army in addition to the IAF and the Indian Navy.

“The development issues and resolutions for integration of critical systems such as rotor, transmission, engines and controls system all were lessons from ALH. Even the implementation of schemes for vibration reduction and enhancement of handling qualities too came from our past experience. The knowledge of weapon system integration and maintainability optimization too were chapters from the past,” the official said.

LCH has a narrow fuselage with tandem seating, crashworthy fixed tricycle type with tail wheel landing gear, reduced IR (infrared) and radar signature, armor protection, aerofoil type armament wing, directional control by push pull cable and capable of day/night operations. It is the first helicopter to have NVG III equivalent in India.

To make the chopper meaner, based on user inputs, the designer had worked on shaping and sizing of the platform, including making the fuselage sleek, reducing the frontal area with aerofoil type armament wing and embedding stealth features by reduced visual, aural, IR and radar signatures. To up the lethal capability, the weapons and mission systems have now been provided self protection systems.

Presently, LCH is integrated with a 20-mm turret gun, 70-mm rockets and air-to-air missiles. Plans are afoot to integrate LCH with air to surface missiles, iron/cluster bombs and anti-radiation missiles.

Advantages galore

To a specific query on what advantages LCH offers pilots during combat, the official said that the high manoeuvrability with use of hingeless rotors and nap-of-the-earth flying capability will make the platform lethal. Nap-of-the-earth-flying or NOE is a very low-altitude type flying to avoid enemy detection. Here the pilots use the geographical surrounding to their advantages.

“With sleek fuselage and crisp controls, we have made a chopper that is really swift and sure. With increasing threat from low-flying aerial weapons, Indian armed forces have been in search of an effective weapon platform to counter and ensure protection of military formations. Equipped with HMDS (helmet mount display system) and FLIR (forward looking Infra Red) and augmenting the onboard weapons, LCH pilots can now detect and destroy any target on ground or in air,” the official said.

LCH is capable of operating from dispersed locations and at ultra low levels proving a protective umbrella from all aerial threats.

“LCH guarantees mission success,” the official added.

At Aero India 2019, the near-production version of LCH (TD-4) will be doing the flying duties while another one will be on the static display.

LCH is a ‘Make in India’ product and would generate employment in the country including MSMEs and service sector, thereby ensuring public-private industry participation. It is a matter of time before LCH would fly in large numbers for Service, similar to its elder sibling the Dhruv.
