摘要:
太阳能飞艇能量全部来自太阳能电池阵列，阵列接收的太阳辐射能量大小决定了飞艇的续航能力。对用于飞艇的刚性晶体硅电池和柔性薄膜电池进行建模，考虑实际电池板单元的尺寸和形状，对比刚性电池的斜平面阵列和柔性电池的曲面阵列在接收能量上的差异，并分析飞艇尺寸对这2种阵列接收能量的影响。对于刚性电池设置4种斜平面阵列布置形式，比较斜平面阵列中电池板的尺寸和形状对接收能量的影响。结果表明：中低纬度处刚性电池的斜平面阵列在全年各天中接收的太阳辐射能量都高于柔性电池的曲面阵列，在高纬度地区则相反。对于刚性电池，电池板在飞艇圆周方向上的尺寸会显著影响斜平面阵列接收的太阳辐射能量。在低纬度地区应增大电池板在圆周方向上的长度以获得更多的辐射能量，而在高纬度地区则应减小长度。
Abstract:The energy of the solar airship comes from the solar cell array, and the amount of solar radiation received by the array determines the endurance of the airship. The rigid crystalline silicon cells and flexible thin-film cells used in the airship were modeled. By considering the size and shape of the actual panel cells, the differences in received energy between the oblique plane array of the rigid cell and the curved array of the flexible cell were compared. The effect of airship size on the received energy of the two arrays was also analyzed. Then, four oblique plane array arrangements for rigid cells were set up, and the effect of the size and shape of the solar panels in the oblique plane array on the received energy was compared. The results show that the oblique plane array of the rigid cell at the low and middle latitudes receives higher solar radiation energy than the curved array of the flexible cell throughout the year, and the opposite is true in the high latitude area. For rigid cells, the size of the solar panels in the circumferential direction of the airship will significantly affect the solar radiation energy received by the oblique plane array. In low-latitude areas, the length of the solar panel in the circumferential direction should be increased to obtain more radiation energy, while in high-latitude areas, the length should be reduced.
