WELDING FIXTURE FOR INLET AND RAM AIR INLET DUCT (PHE LINE) ASSEMBLY OF IJT AIRCRAFT

摘要

IJT-LSP HAL is a Limited series production agency for manufacturing of IJT-LSP aircraft by working on Concurrent Engineering concept. IJT Aircraft is designed by ARDC, HAL. This aircraft is designed for Stage II training of pilots. IJT aircraft has cockpit with twin tandem seats with good visibility for the pilots, modern Active Matrix Liquid Crystal Displays and Head-Up Display (HUD). The aircraft is equipped with a Mission Computer and Integrated Avionics system. 1000 kg of external stores carrying capacity allows fitment of various armaments and fuel drop tanks on the aircraft for effective training. During the build of the aircraft with concurrent engineering philosophy, lot of j innovation were implemented to achieve better quality product, to maintain interchangeability and reduction in cycle time. One out of these improvements is development of an welding fixture for inlet and ram air inlet duct (PHE LINE) assembly to ease the process of welding Assembly, reduction in cycle time and improvement in quality. The Fixture has been designed, fabricated and successfully used for fabrication of inlet & ram air inlet duct assembly of IJT aircraft and presently in working condition.
