Abstract: The sealed cabin of the spacecraft is located inside the vacuum chamber during the vacuum thermal test, and the conventional water vapor measurement methods and water removal methods cannot meet the requirements of sealed cabin. In this paper, a set of measuring device suitable for measuring the moisture content in the sealed cabin is designed to solve the problem of water removal in the vacuum thermal test of the spacecraft sealed cabin, which can meet the requirements for measuring the water vapor in vacuum environment through calibration. The as-designed sealed cabin water removal system is connected to the sealed cabin through a bidirectional sealing flange, which can complete the water removal of the sealed cabin outside the vacuum chamber. The test result shows that this water removal method can ensure that the dew point temperature of the gas in sealed cabin is below 0 ℃ during the vacuum thermal test.

Key words: spacecraft sealed cabin, vacuum thermal test, water vapor measurement, water removal technology
