World's largest linear friction welded component optimised for commercial aviation applications

摘要

TWI Ltd in Cambridge, UK has recently showcased what is claimed to be the world's largest Linear Friction Welded (LFW) component - an aluminium wing rib for commercial aircraft. Comprising 22 rib feet joined to a 2.5 m long baseplate, the wing rib is designed to strengthen aircraft wings, and TWI's application of LFW is claimed to offer a new manufacturing route for these type of components. The LFW process also indicates potential for improved part performance and reduced production costs for the aviation industry.
