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.

AI Technical Summary

Problems solved by technology

The existing thermal control methods for space vehicles are mainly active and passive composite thermal control methods or active thermal control methods. The thermal control materials selected include thermal control multilayer materials, louvers, heat pipes, heating sheets and phase change materials. The installation space is large, and there are high requirements for on-board energy

As for the space small aircraft, it adopts a highly integrated integrated design method, and the space utilization rate is extremely high, which cannot provide enough installation space for the traditional thermal control system, and its energy on the planet is small, so it cannot be used for heating plates, etc. Active thermal control means to provide sufficient energy protection
