平流层飞艇太阳能源系统研究

以平流层太阳能飞艇平台为背景,对平流层太阳能飞艇能源系统展开了分析和研究。文中建立了飞艇表面太阳能电池接收太阳直接辐射、散射辐射、反射辐射的模型。利用该模型对某飞艇太阳能电池进行计算,结果显示飞艇接收的太阳辐射能量与飞艇的工作纬度、季节、太阳能电池阵列表面面积、飞行姿态密切相关。当飞艇的脊背从日出到日落时刻正对太阳光线时,太阳能电池接收到的太阳辐射能量将是最大的。

Study of the Solar Power System of Stratospheric Airships

Concerning the various usage of the stratospheric platform,a study of the solar power system of the stratospheric airship was performed.The model of the solar radiation on the airship surface was developed,including direct radiation,scattered radiation and reflected radiation.With this model,the distribution of solar energy on the solar cell array of a typical stratospheric airship was calculated.The results show that the available solar energy varies obviously with the season,latitude,area of the solar energy cell array and the airship orientation,and reaches at its maximum value at the orientations where the back of the airship is toward the sun rays.
