载人航天器泄复压地面模拟试验方法

Simulation Test Method of Manned Spacecraft Depressurization and Repressurization

为获得泄复压时间曲线,验证载人航天器泄复压系统功能,须进行泄复压地面模拟试验。文章介绍了应用于载人航天器的泄复压试验方法,通过理论计算和试验结果对比,表明了试验方法的正确性和有效性,可为载人航天器后续型号整舱泄复压地面试验提供参考。

To obtain the time curve of depressurization and repressurization for validating depres surization and repressurization system＇s function, the simulation test of depressurization and repressurization is required to be operated. The test method based on manned spacecraft sealed cabin is introduced in this paper. The comparion between calculated result and test data demon strates the correctness and validity of the method. This method can be used to design the depres surization and repressurization test of subsequent manned spacecraft.
