3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Thermal vacuum test thermalvacuumtest
Ground simulation testing to verify or check the spacecraft's ability to withstand the space environment (vacuum, cold black and thermal radiation).
3.2
Temperature ramp rate
Component temperature from the specified low (high) temperature (down) to the specified high (low) temperature rate of change of temperature.
3.3
Temperature stable temperaturestability
For the preset temperature monitoring point reaches the specified temperature and the rate of temperature change is less than the specified value of the thermal state, can be considered temperature stability.
4 test purposes
4.1 appraisal grade thermal vacuum test
Verify the ability of the spacecraft to work under the specified test pressure and appraisal level thermal cycling stress conditions, test the spacecraft subsystems in
Rail work under various modes of performance indicators meet the design requirements.
4.2 Quasi-class thermal vacuum test
Verify that the performance indicators of various subsystems of the first spacecraft on orbit in various working modes meet the requirements and test pressure
And quasi-certified thermal cycling Stress Exposure Potential quality defects that may be introduced due to components, materials, processes, and manufacturing.
4.3 Acceptance grade thermal vacuum test
To verify whether the performance indexes of various subsystems of spacecraft on orbit in various working modes meet the requirements and test pressure and test
Exposure to thermal cycling Stress exposure to potential quality defects that may be introduced due to components, materials, workmanship, and manufacturing.
