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

Brief History

Aerospace Composites Division (erstwhile Composites Manufacturing Division) was conceived as early as the dates of design of Light Combat Aircraft (LCA) & Advanced Light Helicopter (ALH) and has experience in manufacturing and realizing aircraft structures made of composites. Over the years the scope and role of the facility was defined and refined from ‘Advanced Composites Shop’ to ‘Centre of Excellence’. The Division became fully functional as Composites Manufacturing Division 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 has developed capabilities to manufacture and export high precision Composite parts.

The Division is equipped with modern infrastructure in Plant and Equipments like Environmental Control Area of various Classes, -18 degC Cold Store, 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, Laser Tracker, 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, Aerospace Composites Division is one of the top high volume producers of advanced composite aerospace products in the country.
The Division has the following High Tech. facilities:
  • CAD / CAM manufacture
  • CAD (Tool Design)
  • CATIA / UG (NX6) Work Stations
  • 5 Axis Special Purpose CNC Machining Centers
