【摘要】：大氣阻力對高空靜穩(wěn)態(tài)飛行目標運行軌跡的影響是航天測控領(lǐng)域的研究熱點與難點問題。在分析空間飛行器受力狀況基礎(chǔ)上,根據(jù)飛行器運動學狀態(tài)方程,通過數(shù)值模擬方式定量評估了大氣阻力對飛行器運行軌跡影響。結(jié)論表明:在再入段中,大氣阻力是影響飛行器運行軌跡的最主要影響因素,對飛行器落點位置會造成數(shù)百米乃至數(shù)千米位置偏差,同時使落地時間有較大變化。
[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.
