Thermal control method of spatial aircraft

Abstract

The invention discloses a thermal control method of a spatial aircraft. The thermal control method comprises the following steps: firstly sticking a heating piece, a thermistor and a temperature controller on a separating and releasing barrel of the spatial aircraft; before all equipment in the spatial aircraft is mounted, blackening all the equipment, and sticking F46 membranes; applying heat conducting grease or enabling a heat insulating pad to be additionally mounted in an assembly process; and finally coating the spatial aircraft in a multi-layer manner with a multi-layer heat insulating assembly so as to complete the thermal control on the spatial aircraft. Compared with a conventional active-passive complex thermal control manner or a conventional active thermal control manner, the thermal control method disclosed by the invention is simple in design, few in electrical loops and high in reliability; in addition, thermal control equipment can be closely attached to the appearance of the spatial aircraft, so that a small inner space is occupied, the thermal control method has a small influence on external envelope sizes, is high in space utilization rate, convenient and quick to implement and simple to operate, and can be suitable for a quick transmitting task of the spatial aircraft.
