HAL RUDRA,Armed Version of HAL DHRUV,Attack Helicopter,Indian Armed Force
The HAL Rudra is an armed version of HAL Dhruv.It is an attack helicopter manufactured by Hindustan Aeroautics Limited(HAL).It is the Weapon System Integrated(WSI) Mk-IV variant of the Dhruv Advanced Light Helicopter (ALH).Rudra is the first armed helicopter being produced indigenously in India.It is equipped with Forward looking Infra Red and Thermal Imaging Sights Interface,a 20 mm turret gun,70 mm rocket pods,Anti-tank guided missiles and Air-to-Air missiles.
With the integrated sensors,weapons and electronic warfare suite the Rudra uses an upgraded version of glass cockpit used in HAL Dhruv MK-III.
The HAL Rudra Helicopter can be deployed in wide range of missions,including reconnaissance,troop transport,anti-tank warfare and close air support. HAL was contracted to deliver about 76 Rudra ALH Mk-IV helicopters for the Indian Army and the Indian Air Force. The Indian Army plans to equip its Army Aviation Corps with 60 helicopters, forming six squadrons. HAL handed over the first Rudra helicopter to the Indian Army in February 2013.
Design and development Phase
Development for the WSI variant was authorised in December 1998. The prototype made its first flight in August 2007.The integartion trail for armament and electro-optical systems were underwent by Rudra with the final round of weapons firing trails in september 2011.It also included the testing if 20 mm turret gun.
Later on the 70 mm rockets and MBDA mistral air-to-air missiles were tested in November 2011.Mistral is an infrared homing missile,which is capable of striking the targets within the range of 6.5km.The helicopter exceeded the payload and performance requirements at the height of 6km.In September 2012 Ground tests for the first production were completed.
HAL Rudra incorporates a conventional design. Carbon fibre composite materials have been used in construction to achieve weight reduction. The twin engines mounted above the cabin are attached to a four-blade composite main rotor. The cockpit is made of Kevlar and carbon-fibre materials.With this HAL was awarded with a combined order of 76 Rudras for the Indian army, the primary customer, and the Indian air force. It was reportedly that the weapons platforms and avionics of HAL Rudra and the under-development Light Combat Helicopter would be the same.
Rudra has a length of 15.8m, main rotor diameter of 13.2m and a height of 4.9m. The maximum take-off weight of the helicopter is 5,500kg. Rudra can carry a payload of 2,600kg.
Cockpit and Avionics
The Rudra is integrated with all glass advanced cockpit houses crashworthy seats for accommodating 2 crew members.The upgraded cockpit is equipped with Night Visions goggles,multifunctional displays,dual flight controls and automatic flight control system.Its sensors include stabilised day and night cameras,infra-red imaging as well as laser ranging and designation.
HAL Rudra is integrated with modern avionics suite which includes GPS,FLIR,HF/UHF communication radio,Infra-red Friend or Foe (IFF) identification system,Doppler navigation and a radio altimeter.The electro-optic pod,helmet mounted sight and fixed sights increase the efficiency of pilots of destroying the target area by engaging targets using on board weapons.
Engine and Performance
The HAL Rudra helicopter is powered by 2X HAL/Turbomeca Arididen 1H1 (Shakti) turboshaft engines that is capable of producing power of 1067 Kw each.The Full Authority Digital Engine Control (FADEC) system controls all the operations of engines.The Rudra has non retractable fixed-type metal skid landing gear with the tail section features a tail skid to protect the tail rotor during tail-down landings.
The helicopter has a maximum continuous speed of 270km/h. The never exceed speed of the helicopter is 300km/h. Rudra can fly at a maximum altitude of 20,000ft and can climb at a rate of 10.3m/s. It has a range of 660km.
