| 摘 要： | 研究了电动力缆绳拉力产生的原理,建立了电动力缆绳离轨的数学模型和精确地磁场模型,并用Matlab对电动力缆绳离轨的过程进行了数学仿真,对离轨时间进行了预测,为以后进行电动力缆绳空间实验提供依据。离轨时间与地磁场模型的精确程度有密切关系,地磁场模型越精确,估算的离轨时间越接近真实值。

| Abstract: | Space debris is a potential hazard to the safety of normal operating satellites.So it is necessary to take practicable measure to lead the useless satellites reenter into the Earth's atmosphere.Electro-dynamic tethers provide a very promising propulsion system for deorbiting of LEO satellites.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.This paper presents an intensive study of the process of deorbiting using electro-dynamic tether system and forecast the de-orbiting time under accurate geomagnetic models. |
