摘　　要：本文首先建立平流层飞艇的六自由度非线性模型,根据历史气象数据建立急流风场模型,采用遗传算法对飞艇放飞轨迹寻优,对比无风和在急流风场中两种情境下飞艇放飞轨迹、放飞时间及所需能耗的变化,从而分析急流风对平流层飞艇放飞过程的影响。系统仿真结果表明,急流风在平流层飞艇放飞过程中有着显著的影响,仿真结果可以为实际放飞计划提供参考。Firstly, the six-degrees-freedom nonlinear model of stratospheric airship is developed, then the jet stream model is established according to the historical meteorological data. Finally, using genetic algorithm to optimize the ascent trajectory of stratospheric airship without wind and in the jet stream, by comparing the time and energy consumed to find the influence of the jet stream during the stratosphere airship ascenting. The simulation results indicate that the influence of the jet stream during the stratosphere airship ascenting is notable. The simulation results can provide reference for the actual release plan.
