摘要

Air conditioning system of the aircraft must be work at design parameter for the proper comfort level in cabin for passengers of any aircraft. Leakage conditioned air are very common due to wear and tear of the groove dimensions of the duct in the aged fleet. Also it is very difficult to maintain the aged aircraft fleet operative due to the problems of obsolescence. A fresh development of the spare parts is one of the methods to resolve the above problem. Drawings were developed from the groove dimensions of the ducts/pipes. All the O-Rings are working from low to high temperature zone (-20�C to 150�C), material Silicon Rubber Specification NFL17- 101A-50D7 was selected for the development. For manufacturing/development and supply of trial testing samples of O-Ring, rubber moulding vendor was selected who has CEMILAC Type Approved material. All the O-Rings can be directly (if the dimension and type of groove are same with similar working condition) used for the installation of similar duct/pipes joints with proper clamp, system in any aircraft.
