【 摘 要 】

To ensure the safety of the pilot, the design scheme of a ground experiment platform for testing the performance of oxygen supply system under rapid decompression was presented. Detail design process of the subsystems such as vacuum system, rapid decompression system and temperature control system was introduced. Numerical simulations were carried out for the latter two subsystems. The results show that, the requirements both for the temperature uniformity of the experiment cabin and for the rapid decompression time can be achieved, based on the design of the present work which is very valuable for constructing the rapid decompression test platform of oxygen supply system.
