Abstract:
In order to verify whether the thermal control design of the orbit control unit in the core cabin can meet the requirements of the temperature under any working condition during the mission of the space station, I-DEAS/TMG software was used to determine the heating power required by the orbit control unit under extreme low temperature conditions, and the maximum temperature under extreme high temperature conditions was predicted.The on-orbit flight shows that the flight temperature of the orbit control unit verifies the correctness of the theoretical calculation, and the deviation between them is about 3.7.The larger the area of nozzles exposed to the sun, the higher the temperature of the heads and solenoid valves.When the solar angle is equal to 58°, the illuminated area of the nozzle is the largest.Under low temperature conditions, the temperature of unit head with propellant flow and solenoid valve is higher than 6.8 ℃,which meets the index requirement higher than 0 ℃.Inertial flight attitude belongs to high temperature condition for the pitching unit, which is different from the thermal control coating state of the previous unit, ensures that the temperature of the solenoid valves is lower than 40 ℃ under extreme high temperature conditions, which provides guarantee for the reliable operation of the solenoid valves during the 15 year mission of the space station.
