提出一种低温火箭仪器设备隔热安装结构并对其隔热效果进行低温摸底试验研究。隔热安装结构由聚酰亚胺隔热垫与聚醚醚酮支座组成,试验结果表明所设计的隔热安装结构可有效隔离低温环境的影响,使仪器设备表面温度保持在0℃以上,满足仪器设备的使用要求。
A kind of low temperature rocket equipment thermal insulation installation structure is proposed and its insulation effect is tested at low temperature. The thermal insulation installation structure consists of a polyimide thermal insulation pad and a polyetheretherketone support. The test results show that the designed thermal insulation installation structure can effectively isolate the influence of low temperature environment, keep the surface temperature of the equipment above 0 DEG C, Meet the equipment requirements.
