Welcome to the Composites Manufacturing Division, Hindustan Aeronautics Limited.  (Helicopter Complex)
 

BRIEF HISTORY

Composites Manufacturing Division, the youngest outfit in this gigantic set-up was conceived, as early as the dates of design of Light Combat Aircraft (LCA) & Advanced Light Helicopter (ALH) and having over 15 years of experience in manufacturing and realizing aircraft structures made of composites. Over the years the scope and role of the facility was defined, refined from Advanced Composites Shop to Centre of Excellence. The Division became fully functional from April 2007 as a Strategic Business Unit (SBU) of HAL.

Currently, the Division is manufacturing the composite structural parts for Advanced Light Helicopter (ALH), Light Combat Aircraft (LCA), Light Combat Helicopter (LCH), Light Utility Helicopter (LUH) and PSLV/GSLV.

In a major diversification initiative, the Division is going to manufacture and export high precision Aircraft Composite parts for Boeing 777 Commercial Aircraft & Boeing P-8I Military Aircraft. Division is currently manufacturing and exporting Cowlings for Eurocopter, France.

The Division is equipped with modern infrastructure in Plant and Equipment like Environmental Control Area of various Classes , -20degC Cold Stores, Autoclaves, High precision 5-Axis CNC Machining Centers, Automated Ply Cutting Machines, Surface Enhancement Machine (Shot Peening ), Hot Platen Presses, Computer Controlled Air Circulating Ovens, Laser Projection Systems for Lay –up, CT-Scan ,Ultrasonic C-Scan, Coordinate Measuring Machines, Universal Testing Machines and material test laboratory for composite material testing.

With average production rates of several thousand composite parts annually for many of our products, Composites Manufacturing Division is one of the top, high volume producers of advanced composite aerospace products in the country.
