【摘要】：大氣阻力對(duì)高空靜穩(wěn)態(tài)飛行目標(biāo)運(yùn)行軌跡的影響是航天測(cè)控領(lǐng)域的研究熱點(diǎn)與難點(diǎn)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(yùn)動(dòng)學(xué)狀態(tài)方程,通過數(shù)值模擬方式定量評(píng)估了大氣阻力對(duì)飛行器運(yùn)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(yùn)行軌跡的最主要影響因素,對(duì)飛行器落點(diǎn)位置會(huì)造成數(shù)百米乃至數(shù)千米位置偏差,同時(shí)使落地時(shí)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.
