摘　　要：临近空间飞行器依靠搭载的柔性太阳电池组件和储能电池组构成的能源系统,可在临近空间长期飞行和驻留,完成地面观测、无线通信、军事侦察等任务,因而成为各国航天航空领域发展的热点之一。由于太阳电池组件能量转化效率只有20%左右,大部分太阳光能量吸收后转化为热。这部分热传导到高空气球内部,将造成内部气流紊乱,增加高空气球姿态控制难度,而温度升高引起的热应力甚至可能破坏柔性太阳电池组件。本文通过计算机模拟太阳组件在高空气球蒙皮上的工作条件,建立组件结构模型及热传递数学模型,仿真得到电池组件实际工作时的温度场和应力场分布情况,对高空气球供电组件的结构优化、工作状态的掌握具有指导意义。With the energy system composed of flexible solar cell modules and energy storage battery packs,near space vehicles can fly and reside in near space for a long time,and complete tasks such as ground observation,wireless communication,and military reconnaissance,therefore,they have been one of the hot spots in the development of aerospace field all over the world.However,the solar cell module energy conversion efficiency is only about 20%,and most of the solar energy is converted into heat after being absorbed.If this part of heat conduction is transferred to the interior of an airship,the airflow in the airship will be turbulent,which will increase the difficulty in controlling the attitude of the airship,and the thermal stress caused by the temperature increase may even damage the flexible solar cell modules.In this paper,the working conditions of solar cell modules on the stratospheric airship skin are simulated,and the module structure model and the mathematical model for heat transfer are established.The obtained temperature field and stress field distributions are of guiding significance for the structure optimization and working status mastering of solar cell modules for airships.
