通过选取LEO区域中两种典型材料的小尺度空间碎片,分别建立了相应的强激光与靶材的冲量耦合模型,研究了高能脉冲激光与靶材作用下碎片速度的变化规律。在此基础上建立了激光辐照作用下小尺度空间碎片的变轨模型。通过仿真分析,对假定功率激光器作用下两种典型材料空间碎片轨道参数的变化规律进行了数值模拟,并讨论分析了碎片自旋角速率及不同功率的激光器对碎片清理效能的影响规律。研究结果表明,在假定功率的天基平台激光器作用下能在一个飞行周期内辐照两种典型材料碎片达到降轨清除效果,为天基平台激光清除空间碎片技术的应用提供了必要的理论基础。
By choosing small scale space debris of two typical materials in the LEO region, corresponding impulse coupling models of strong laser and target are established respectively, and the changing rules of debris velocity under the action of high energy pulsed laser and target are studied. On this basis, a model of small-scale space debris orbit change under laser irradiation is established. Through the simulation analysis, the variation regularity of orbital parameters of two typical materials under the action of a hypothetical power laser is numerically simulated, and the influences of the spin rate and the power lasers on the debris cleaning efficiency are discussed. The results show that under the hypothetical power-based platform laser, two kinds of typical material fragments can be irradiated in one flight cycle to achieve the orbital removal effect, which provides the necessary theoretical basis for the application of the space-laser technology in laser-clear space-based platform .
