  • In this application, the lorentz force generated by the interaction between the current in the wire and the geomagnetic field produces an electro-dynamic drag leading to a fast orbital decay . in this paper, we make an intensive study of the process of de-orbiting using electro-dynamic tether system . the concrete work includes : firstly, i have studied the basic principle of how to generate the electro-dynamic drag, modeled via accuracy geomagnetism, made a concrete analysis of the de-orbiting duration, the magnitude and direction of electro-dynamic drag under the action of the dipole and accurate geomagnetic models, set up a counterbalance between electro-dynamic torque and gravity gradient torque, emulate the de-orbiting process of spacecraft, and compared the change of six orbital factors and the de-orbiting duration under the action of the dipole and accurate geomagnetic models
    本文對(duì)基于電動(dòng)力纜繩的航天器離軌過(guò)程進(jìn)行了深入研究,具體工作如下:首先,本文研究了電動(dòng)力纜繩產(chǎn)生電動(dòng)力拉力的基本原理,建立了精確地磁場(chǎng)模型;分別在偶極子模型和精確地磁場(chǎng)模型作用下,對(duì)電動(dòng)力拉力的大小、方向、離軌時(shí)間及電動(dòng)力纜繩傾角的大小進(jìn)行了計(jì)算分析;建立了電動(dòng)力力矩與纜繩系統(tǒng)重力梯度力矩的平衡關(guān)系;分析了電動(dòng)力力矩為系統(tǒng)提供能量的原理;最后分別在偶極子地磁場(chǎng)模型和精確地磁場(chǎng)模型作用下,對(duì)受電動(dòng)力纜繩作用的航天器的離軌過(guò)程進(jìn)行仿真,分析了在不同精度地磁場(chǎng)模型下,航天器離軌過(guò)程中各軌道參數(shù)的變化情況,并比較了不同模型對(duì)離軌時(shí)間的影響。
