摘　　要：为在当前已有技术发展水平下挖掘太阳能无人机性能潜力,结合工程研制背景建立了基于航迹规划设计的太阳能采集分析系统,研究了圆形、四边形、8字形这三种典型航迹的太阳能采集情况及内在机理,量化揭示了在航迹设计中减小无人机滚转角幅度可增大太阳能采集。同时,提出了一种8字形航迹参数化方法并在某大展弦比太阳能无人机高空飞行试验中进行了验证,取得了良好效果。此外,依据提出的8字形参数化方法和最大太阳能采集航向生成了相应的变航向8字形航迹,仿真结果显示,该方式进一步提升了太阳能采集量,为人在回路的太阳能无人机航迹设计提供了一种简捷有效的方法,具有一定的工程指导意义。In order to explore the potential capability of solar-powered UAV(Unmanned Aerial Vehicle)under the current level of technology,combining with the engineering background,a solar energy harvesting and analysis system based on flight path planning design is established. Three typical flight paths including circular shape, quadrilateral shape and 8 shape are studied and the internal mechanisms are analyzed, which quantitatively reveal the law that decreasing roll angle of UAV can increase the solar energy harvesting.Furthermore, a parameterization method for 8 shape flight path is proposed and verified in a high-altitude flight test of a solar-powered UAV which has a large aspect ratio, and good results are achieved. Moreover,according to the proposed parameterization method and the maximum solar energy harvesting heading, the corresponding variable-heading 8 shape flight path is generated. Simulation results show that the capability of solar energy harvesting is enhanced, which provide a simple and effective method for the flight path design in the term of human-in-control-loop. This finally shows positive meaning in the field of engineering applications.
