Abstract
Objective To develop a kind of rapid decompression equipment replacing the toughened glass simulating the state of aircraft cabin glass bursting on the fly.Methods The metallic membrane was used to isolate both chambers with different air pressures.The areas of decompression membrane and path were determined by calculating on the basis of aircraft decompression altitude,cabin pressure differential and decompression time.The structural strength was determined according to enduring force of the metallic membrane.The membrane was ejected by high pressure air using the ejection launch technology of aircraft missile.The result of simulating aircraft cabin glass bursting on the fly was achieved.Results The rapid decompression equipment ejected by air pressure in low-pressure chamber could achieve the state of simulating aircraft cabin glass bursting on the fly,and the best decompression time was 0.16 s.Conclusion The rapid decompression equipment ejected by air pressure accomplishes the decompression preparative in short time with easy operation,and can satisfy the desired requirements for the performance and precision.关键词
