摘要
泡沫增阻法是一种清除空间碎片的新方法。首先分析了该方法的使用范围和特点,建立了其运动学模型,提出了泡沫喷射误差的计算方法,研究了影响喷射误差的4种因素。在此基础上,分析了清除不同尺寸的空间碎片所允许的喷射误差。仿真结果表明,泡沫增阻法适用于清除尺寸为米级的空间碎片,提高卫星的轨道精度是减小喷射误差最有效的手段,并对所需的轨道精度提出了要求,为该方法的进一步深入研究和实施提供了参考。
Foam drag augmentation method is a new method to remove space debris.Firstly,the application scope and characteristics of the method are analyzed,and its motion model is established.Then the calculation method of ejection error of foam is put forward.Afterwards,four influence factors of ejection error are studied.On the basis,the allowable errors to remove space debris of different sizes are analyzed.Simulation results indicate that the foam drag augmentation method is suitable for removing debris with size of meters.The results also show the most effective means to reduce the ejection error is to improve the orbit accuracy of the satellite,meanwhile the required orbit accuracy is proposed,which can provide valuable reference for further research and implementation.
