摘要
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。
The total leakage rate of the spacecraft is usually tested by the mass spectrometry leak detector (MSLD) to measure the accumulated tracer gas. in order to increase the total leakage test accuracy, the effect of standard gas calibration time on the total leakage rate test results of the spacecraft was analyzed, and the total leakage rate calculation formula was amended accordingly.
