THE COMPANY

ROTARY WING RESEARCH & DESIGN CENTRE(RWRDC)The Rotary Wing Research & Design Centre of Helicopter Complex, HAL, with modern facilities and state-of-the-art technologies spearheads HAL's thrust towards excellence in the field of Helicopter design and associated technologies to meet the requirements of military and civil customers. The Centre has successfully designed and developed Advanced Light Helicopter (ALH) and also upgraded Cheetah and Chetak Helicopters.

DEVELOPMENTDevelopment of LCH was taken up on digital platform using 3D CAD and PDM(Product Data Management) tools. Three prototypes have been built which are presently undergoing development flight trials to validate design objectives.

LIGHT COMBAT HELICOPTERThe Light Combat Helicopter is a twin-engine, dedicated combat helicopter of 5.8-ton c l a s s f e a t u r i n g n a r r o w f u s e l a g e w i t h t a n d e m configuration for Pilot and Co-p i l o t / W e a p o n S y s t e m O p e r a t o r ( W S O ) . I t incorporates a number of stealth features such as reduced visual, aural, radar and infra-red signatures, and crashworthy landing gear for better survivability.

With twin Shakthi engines, LCH features the latest design concepts to improve reliability and survivability against battle damage. LCH has excellent maneuverability and Nap of the Earth (NOE) flying capability. Easy maintainability is another important consideration in design.

LCH is equipped with some of the common systems of ALH such as Integrated Dynamic System (IDS), Rotors, Anti-Resonance Isolation System (ARIS), Integrated Architecture and Display System (IADS), Dual redundant Hydraulics, Basic Electrical and Avionics. The helicopter is fitted with tail wheel type crashworthy landing gear.
