Abstract:
A new type of plate heater was adopted to improve the heating method of the 490 N engine head. The finite element software I-DEAS/TMG for thermal analysis was used to simulate the temperature field of the engine head. The temperature resistant ability of the thermal control module and the engine bracket was evaluated. In addition, the temperature criterion to shut down the 490N engine was proposed during the flight control. The temperature control loop and the design of its temperature control point are elaborated, and the control strategy of temperature is introduced. Finally, the temperature control data of the engine in orbit flight test is given and the effectiveness of thermal control design is validated.
