Abstract: The environmental simulation technology for the ambient pressure thermal test of the manned spacecraft is tested through the heat leakage analysis of the space station, the ambient pressure test for the thermal insulation behavior of the multi-layer insulator (MLI), and the test capability analysis of the large-scale ambient pressure thermal test validation system. Based on the results, a thermal test is conducted for the pressurized cabin of a space station. The effectiveness of the environmental simulation technology is validated by the heat leakage comparison based on the test results.
