航天器的总漏率测试一般采用氦质谱大气累积检漏法,为了提高总漏率测试的准确度,对目前航天器总漏率测试过程放样时间对测试结果的影响进行了研究分析,并对总漏率计算公式提出相应的修正。
In order to improve the accuracy of the total leak rate test, the total leakage rate test of the spacecraft generally uses helium mass spectrometry. In this paper, the impact of the setting time of the current spacecraft total leak rate testing process on the test results is studied and analyzed The total leakage rate formula to make the appropriate amendments.
