舱外航天服热平衡试验热流计算工作量大,有必要改进外热流模拟方法。文章提出用红外加热笼分类模拟舱外航天服包围面上外热流,并给出包围面外热流的概念,分析包围面上外热流,得出外热流模拟改进方法的关键措施,且用仿真方法验证了模拟方法的可行性。
The heat balance calculation of heat balance test in extragalactic spacesuit requires a lot of workload and it is necessary to improve the simulation method of external heat flow. The article proposes to classify the external heat flux on the enveloping surface of the space suit by infrared heating cage and to give the concept of heat flux on the surrounding surface and to analyze the external heat flux on the enveloping surface. The key measures to improve the external heat flux simulation are obtained and verified by the simulation method The feasibility of the simulation method.
