摘　　要：薄膜太阳能电池是平流层飞艇能源系统的主要组成部分且会对飞艇内部氦气温度产生重要影响。针对表面铺设薄膜太阳能电池对飞艇内氦气温度造成的影响,建立了铺设薄膜太阳能电池的平流层飞艇数学和物理模型。将太阳能电池视为理想的等温边界,利用CFD分析软件进行了仿真,得到了飞艇内部氦气温度的分布及变化情况。仿真结果表明,薄膜太阳能电池会造成飞艇表面局部区域温度过高,内部氦气温度变化与电池背板温度及铺设面积成正比。仿真结果为飞艇总体热设计及超热控制提供了设计依据。As a major part of the stratosphere airship energy system, thin film solar cells have a profound effect on the temperature of the internal helium. The paper builds the mathematical and physical models of the stratosphere air- ship with thin film solar cells over its surfaces, which profoundly influence the temperature of inner gas. Transient nu- merical simulations are conducted in CFD numerical simulation software, the solar cells＇ areas are treated as the iso- thermal boundary and distribution and change of the temperature of inner gas are obtained. The results indicate that the solar cells can cause the temperature rise of local areas of airship surface and inner gas. The change of inner gas temperature is proportional to the variation of the back temperature and laying areas. The simulation results will provide a calculation basis for the general thermal design and super thermal control of the stratosphere airship.
