一、序言当人造卫星和宇宙飞船等空间飞行器(以下简称飞行器)绕地球轨道作周期运转的时候,由于飞行器不断地在面对太阳的“向阳面”和地球阴影区的“背日面”通过,如不采取适当的控制,将经受着大致为±200℃的温度交变,在这种情况下,保证飞行器内部的能源、电子仪器以及宇航员正常工作的温度环境,是一项很重要的任务。根据宇宙空间热传递过程可知,投射到飞行器的热量包括三部份(见图1):①由太阳来
I. INTRODUCTION When space vehicles such as satellites and spacecrafts operate cyclically orbit around the earth’s orbit, as the aircraft continually changes its position on the sunward side of the sun and the shadow of the earth The “surface” passes without proper control and will experience a temperature change of roughly ± 200 ° C, in which case the temperature environment that ensures the energy inside the aircraft, the electronic equipment and the normal working of the astronaut is a A very important task. According to the heat transfer process in space, the heat projected to the aircraft includes three parts (see Figure 1): ① the sun
