Solar energy is a key factor for high altitude airships to achieve long endurance flight. In order to receive more solar energy and improve the endurance performance of airships, this paper presents a multidisciplinary design methodology to obtain an optimal configuration of the high altitude airship considering the energy optimization. First, a parameterized shape of the airship is proposed and the aerodynamic characteristics are obtained and integrated through a kriging model. Then the solar radiation and photovoltaic (PV) array models are introduced and validated by a ground experiment. After elaborating the structure, propulsion and energy subsystems, an external-internal loop optimization process is carried out to minimize the total weight considering the maximum solar power from PV array. The result of the multidisciplinary design shows an obvious increase on the received solar energy to 3.36 GJ compared with 0.45 GJ for the traditional design, which has a great potential to save the weight of the PV array laid on the airship surface.

Further, the effects of the latitudes, dates and wind conditions on airship endurance performance are analyzed and in order to achieve long endurance flight, an adaptability discussion is carried out through a multi-objective optimization process. The result indicates that the improved design has a higher adaptability ratio in different environments compared with the single input design. It suggests that an adaptability design of high altitude airships might be an effective approach in airship engineering applications.

太阳能是高空飞艇实现长时间耐力飞行的关键因素。为了接收更多的太阳能并提高飞艇的耐力性能，本文提出了一种多学科设计方法，以在考虑能量优化的情况下获得高空飞艇的最佳配置。首先，提出了飞艇的参数化形状，并通过克里金模型获得了空气动力学特性并进行了综合。然后介绍了太阳辐射和光伏（PV）阵列模型，并通过地面实验对其进行了验证。在详细说明了结构，推进和能量子系统之后，考虑了来自光伏阵列的最大太阳能，进行了内外循环优化过程以使总重量最小化。

此外，分析了纬度，日期和风况对飞艇耐力性能的影响，为了实现长耐力飞行，通过多目标优化过程进行了适应性讨论。结果表明，与单输入设计相比，改进后的设计在不同环境下具有更高的适应性比。这表明高空飞艇的适应性设计可能是飞艇工程应用中的一种有效方法。
