摘要
采用数值离散方法建立临近空间飞艇不规则曲面太阳能电池性能计算模型,完成不同航向角条件下太阳能电池性能参数研究。基于太阳能电池性能计算模型,以太阳能电池面积最小为目标,建立太阳能电池布局优化平台,得到不同航向角条件下太阳能电池最优铺设方案。研究表明:采用平面太阳能电池模型和曲面太阳能电池模型计算得到的太阳能电池输出性能具有显著差异,临近空间飞艇航向角对太阳能电池输出性能有重要影响。布局优化可以在保证输出能量足够的条件下显著减小太阳能电池的面积和质量,在航向角为90°条件下,通过布局优化,可以使太阳能电池铺设面积减小21.9%。
The computational model of a solar array on an irregularly curved surface for its application to a stratospheric airship was established using numerical discrete method,and parameter investigations under different heading angles of the airship were carried out.A layout optimization platform based on the solar radiation and solar array models was developed to optimize the area of the solar array,and the optimum layouts of the solar array under different heading angles were obtained.Results indicated that flat and curved surfaces can lead to large differences in the performance of the solar array,and the heading angles strongly affected the output power of solar cells.The proposed optimization method can help effectively reduce the area and weight of the solar array under the condition of sufficient output energy of the solar array.Moreover,the area of the solar array was reduced by 21.9%when the heading angle was 90°.
