【摘要】：大气阻力对高空静稳态飞行目标运行轨迹的影响是航天测控领域的研究热点与难点问题。在分析空间飞行器受力状况基础上,根据飞行器运动学状态方程,通过数值模拟方式定量评估了大气阻力对飞行器运行轨迹影响。结论表明:在再入段中,大气阻力是影响飞行器运行轨迹的最主要影响因素,对飞行器落点位置会造成数百米乃至数千米位置偏差,同时使落地时间有较大变化。
[Abstract]:The influence of atmospheric resistance on the trajectory of statically and steady-state flying target is a hot and difficult problem in the field of space measurement and control. Based on the analysis of the force state of the space vehicle and the kinematics equation of state, the influence of atmospheric drag on the trajectory of the vehicle is quantitatively evaluated by numerical simulation. The results show that the atmospheric drag is the most important factor to affect the flight trajectory in the reentry section, which will cause the position deviation of hundreds of meters or even thousands of meters to the position of the aircraft landing point, and make the landing time change greatly at the same time.
