针对火星气球的温度特性开展研究,首先分析了火星大气的特殊热环境;归纳了影响火星气球温度特性的主要环境因素;设计了两种不同蒙皮辐射特性的原型超压气球;建立了计算火星气球稳态温度分布的模型,并做了合理的简化;选择了热、冷、任意时刻及特殊工况进行气球的蒙皮和内部气体温度计算。结果表明,通过改进蒙皮辐射特性的设计,可以满足火星气球在特定工况下飞行的温度要求。
Aiming at the temperature characteristics of the Martian balloon, firstly, the special thermal environment of the Martian atmosphere is analyzed; the main environmental factors affecting the temperature characteristics of the Martian balloon are summarized; two prototype overpressure balloons with different skin radiation characteristics are designed; Balloon steady-state temperature distribution model, and made a reasonable simplification; Select the hot, cold, any time and special conditions for the balloon skin and internal gas temperature calculation. The results show that by improving the design of the radiation characteristics of the skin, the temperature of the Mars balloon can be satisfied under certain operating conditions.
