摘要
为分析空间电动绳系的运动特性,从一般力学角度出发,结合电动力学知识,建立了近地轨道空间电动绳系推进飞行的动力学模型,得出了多种初始条件下的数值计算结果,并据此对电动绳系航天器的轨道机动过程进行了详尽的讨论,阐明了系统在轨道高度变化的同时,其轨道面也会发生变化,而且导电系绳还会旋转与弯曲变形等规律．此外,还对电动绳系推进系统的效率和地球自转的影响进行了估计．
To study the kinetic characteristics, the motion of the LEO electrodynamic tethered （EDT） propulsion system is modeled, in this paper, from the angle of mechanics and electrodynamics. The numerical solutions under various initial conditions are obtained, based on which the motion of space EDT system is discussed. The effects of Ampere force, the tether＇s deformation and deflexion, on the orbital plane, as well as on the orbital altitude, are studied. In addition, the efficiency of space EDT system and the effect of the earth＇s rotation are evaluated.
