摘　　要：为完成充气式快速部署太阳能无人机总体设计,首先,考虑箭载发射或机载投放等快速部署方式对无人机尺寸和质量的限制,从飞行器翼载荷可行域的角度出发,基于广义能量法,建立了充气式太阳能飞行器能源动力模型、全天及夜晚能量平衡下的翼载荷边界模型;其次,研究了光伏电池转换效率及铺装率、储能电池能量密度及功率因子等参数对其翼载荷可行域的影响,分析了各参数间的耦合关系;最后,对比了常规、充气式太阳能飞行器翼载荷可行域。研究结果表明:充气式太阳能无人机翼载荷可行域受光伏电池转换效率、储能电池能量密度及功率因子的影响较大,光伏电池的铺装率对翼载荷可行域的影响较小;在不同翼型下,充气式太阳能无人机的翼载荷可行域明显大于常规太阳能无人机的翼载荷可行域,且充气式太阳能无人机最大飞行高度明显比常规太阳能无人机的大。In order to complete the general design of inflatable rapid deployment solar UAV,firstly,the limitations of rapid deployment modes,such as rocket carrying and launching or aircraft carrying and launching on the size and mass of UAV were considered.From the perspective of aircraft wing load feasible region,the energy dynamic model of inflatable solar UAV(unmanned aerial vehicle)and the wing load boundary model in the energy balance of all day and night were established,based on the generalized energy method.Secondly,the effects of photovoltaic cell conversion efficiency and paving rate,energy density of energy storage battery and power factor on the wing load feasible region were studied and the coupling relationship between various parameters were analyzed.Finally,the wing load feasible region of conventional and inflatable solar aircraft was compared.The results show that the feasible wing load domain of inflatable solar UAV is greatly affected by the conversion efficiency of photovoltaic cells,energy density and power factor of energy storage batteries,and the paving rate of photovoltaic cells has little influence on the feasible domain of wing loading.With different airfoil types,the wing load feasible domain of inflatable solar UAV is significantly larger than that of conventional solar UAV,and the maximum flight height of inflatable solar UAV is significantly higher than that of conventional solar UAV.
