天基激光清除空间碎片是目前空间碎片清除方式的热点研究内容,圆锥体是空间碎片的典型形状。利用激光烧蚀靶材的烧蚀反喷理论,对不同角度激光烧蚀圆锥体碎片建立数学模型,得到了激光烧蚀力与烧蚀力矩随激光烧蚀角度的变化规律,同时将圆锥体的高径比作为变量,研究了圆锥体形状对于烧蚀效果的影响,为天基激光清除圆锥体空间碎片提供了分析理论和方法。

Removing space debris by space-based laser is a hot research topic of current space debris removal methods, and the cone is one of typical shapes in numerous space debris. Based on the reverse spraying impulse theory under laser irradiation, the paper establishes a mathematical model for laser ablation of conical debris at different angles, and obtains the variation of laser ablation force and ablation moment with laser ablation angle. At the same time, the ratio of height to radius of a cone is used as a variable to research the effect of conical shape on ablation, which provides analytical theories and methods for removing space debris by space-based laser.
