【摘要】 首先介绍了平流层气球的应用意义及进行轨迹控制的必要性,然后描述了一种基于不同海拔风速差的轨迹控制方法,简要说明了平流层风速随海拔的变化规律,在此基础上研究了包括超压气球和轨迹控制系统在内的气球飞行系统各部分特点,最后简单分析了整个飞行系统的建模与仿真中的要点问题。结果表明,这种轨迹控制方法是一种几乎不需要消耗能源的有效轨迹控制方法,具有较高的应用价值和推广价值。更多还原

【Abstract】 Recent interest in very long duration stratospheric scientific balloon flights has been stimulated by a desire to obtain high quality scientific observations form constant-altitude stratospheric platforms.A method of controlling trajectory of balloon system is presented.The trend of stratospheric wind speed variation with altitude is indicated and characteristics of several parts of balloon systems including super-pressure balloons as well as trajectory control systems are discussed.Finally,some issues concerning modeling and simulation are analyzed.This method of trajectory control,consuming little power,proved to be an effective method with high value of application and popularization.更多还原
