平流层飞艇上表面太阳辐射强度的分布是影响光伏阵列输出性能的重要因素。为分析平流层飞艇飞行姿态对其上表面太阳辐射强度分布特征的影响,并建立飞艇动力学模型与太阳辐射物理模型交互耦合的计算模型。使用该模型对算例飞艇进行计算分析,量化得出飞艇偏航角和俯仰角耦合变化对飞艇表面太阳辐射强度分布影响的结果,并比较分析了太阳辐射强度受飞艇飞行姿态影响的特性。研究结果可用于指导太阳能电池阵在平流层飞艇上的优化布局和阵列构型。

Solar radiation intensity distribution combined with stratospheric airship flying gesture

The distribution of solar radiation intensity on the upper surface of the stratospheric airship is an important factor affecting the output performance of photovoltaic arrays. In order to analysis the influence of the dynamic change of the flight attitude of the stratospheric airship on its upper surface solar radiation intensity distribution characteristics and establish a calculation model of interactive coupling between the airship dynamics model and the solar radiation physical model was established. By using this mode, a certain airship example was calculated, the solar radiation intensity distribution on the upper surface of the stratospheric airship was also proposed under flight yaw and pitch angle change, and the characteristics of solar radiation intensity affected by airship flight attitude. The result can be used to guide the optimized layout and array configuration of the solar array on the stratospheric airship.
