摘　　要：建立了太阳能飞机方案设计阶段的仿真模型,包括能量流动、太阳能采集、蓄电池、飞机运动及能量管理等部分。通过仿真比较了太阳能电池固定安装和可转动安装两种飞机方案的太阳能采集效率和续航性能。仿真结果表明,方案2的设计采集效率优势明显,在光照匮乏时飞机飞行时间较长。该模型可用于太阳能飞机方案设计阶段的验证分析,为方案的选择和改进提供依据。This paper presents a simulation model of solar-powered airplane for the conceptual design.Components of the model include energy flow,solar energy collection,secondary battery,and airplane motion and energy management.In the mean time,two concepts of solar-powered airplane were compared respectively with fixed solar planes and rotational solar planes on their efficiency of solar energy capture and airplane endurance.It was seen that the second concept showed obvious advantage on the efficiency of solar energy capture and its endurance was longer during the days with scarce solar radiation.Those discussed in the paper present that the model could be used for verifying and analyzing the concepts of solar-powered airplane.
