平流层飞艇太阳电池系统产能分析
|
摘要
平流层飞艇曲面太阳电池的产能与飞艇所在位置、驻空时间、飞行姿态、太阳电池布局等有着密切的关系。通过对太阳辐照模型的分析,结合平流层飞艇驻空期间方位角的变化,采用投影法分别计算曲面太阳电池各投影面的产能,从而计算出太阳电池在驻空过程中的动态发电功率。分析结果表明:曲面太阳电池在水平面内的投影部分是主要产能部分,受飞艇方位角的影响较小;垂直面内的投影部分产能较少,受飞艇方位角影响较大。
The power of airship′s curved solar array is closely related to the position of airship, time of flight, flight of attitude, layout of solar array and so on. Through the analysis of solar radiation model, and combined with the variation of azimuthal angle in the course of stratospheric airship′s flight, the projection was used to calculate the power of curved solar array, thus the dynamical power generation of the airship was calculated. The analysis results show that the projection in horizontal is the main component of curved solar array′s power, which is little influenced by airship′s azimuthal angle; the power of projections in vertical is smaller, which is more easily affected by airship′s azimuthal angle.
