Abstract: Space thrusters are key components of the propulsion system used for controling the orbit and attitude of the spacecraft. To ensure start-up temperature of the thruster and its reliable operation, special thermal control devices must be installed. This paper mainly summarizes different thermal control requirement for various kinds of space thrusters. The key technologies of sheathed thermal control elements are discussed. Also its classification, performance and application are addressed. Test methods and criteria for sheathed thermal control elements are introduced and the development direction of sheathed thermal control elements is proposed.
