大跨时空任务背景下的太阳能无人机任务规划技术研究进展

Using the mission planning technology to optimize the flight trajectory and dynamical parameters, the energy utilization of the Solar Powered Unmanned Aerial Vehicle (SUAV) can be effectively improved, making it qualified for many flight missions in large time spans and space spans. In this paper, the research development of the SUAV mission planning technology in large time spans and space spans is reviewed from the energy modeling, endurance evaluation, and energy management strategy. In energy modeling, the current mainstream solar radiation models and energy production basic frameworks are introduced. In endurance evaluation, the present index designs and application methods are analyzed. In energy management strategy, the current research status is combed through in terms of energy comprehensive utilization, gliding mechanism in wind fields, trajectory optimization method, and application for specific missions. Finally, promising research directions of this field are prospected.
