摘　　要：为提供一种可行的高空飞艇动力系统设计,对飞艇所受到的力、能源系统、飞艇重量进行了研究,并对不同动力布局的飞艇所受到的气动力进行了数值仿真。引入混合浮升气体以提升飞艇的单位升力,并考虑了过热对飞艇升力的影响;对能源系统采取恶劣条件作为飞艇的设计点,计算了冬至日时单位面积的太阳直接辐射量;采用能量平衡方法,对飞艇能源系统进行分析;应用以上方法初步确定了高空飞艇的基本参数。此外,建立了两种不同的动力布局模型,并对不同模型进行了气动数值仿真,得出不同布局对飞艇气动性能的影响,为设计提供了参考。The research on configuration design of high altitude airship （HAA） is just beginning. There are a lot of differences between HAA and conventional airship. In order to provide a viable airship design, the force of airship, energy system and airship weight were studied, and then aerodynamic of airship was simulated. In HAA configuration design, there are too many interdependent parameters to be taken into consideration, which are involved in the selec- tion of HAA energy system, shape, propulsion system and so on. In the exploration, we selected mixed gas to im- prove HAA＇s lift; besides, selected harsh solar radiation conditions as the design point of energy system, then the so- lar radiation on the horizontal projection surface was calculated. By using the energy balance method, HAA energy system was analyzed. Finally, the basic parameters of HAA was presented . In the full paper, we explained in detail our iterative method of HAA design. Besides above, the aerodynamic characteristics of different models were also cal- culated.
