CSIR lab to make composite air-frame parts for Tejas
CSir-national aerospace laboratories (csir-nal) has received a ₹100 crore order for delivering critical composite air-frame components to Hindustan aeronautics limited (Hal) for the lcatejas, a standard aircraft with full operational capability.
minister of science and technology and vice president, csir, Harsh Vardhan highlighted the csir’s commitment to the make in india initiative. “The cutting-edge technology is one of the critical technologies that make the lca a 4th generation fighter aircraft,” said Vardhan.
csir director general girish Sahni said the use of co-curing technology (a joining method regarded as an adhesive bonded joining technique) in lca has resulted in 40 percent reduction in the part count, 50 percent in the number of fasteners, and 30 percent in the assembly time as compared to a conventional metallic air-frame. The usage of composites has led to an overall weight reduction of about 20 percent in the air-frame.
csir-nal has now further bagged an order to supply an additional 20 sets of parts for full operational capability standard aircraft at a cost of ₹100 crore.csir-nal’s collaboration with the lca programme started from technology demonstrator to prototype development to limited series production.
