美国海基导弹拦截卫星任务的毁伤分析

基于经验模型和基本假设,研究了航天器撞击的解体特性,计算了碎片的尺寸分布、面质比分布和速度分布,考虑生存高度和大气阻力的影响计算了各种碎片的轨道寿命,提出了碎片留轨比例及数量的计算公式,分析了不同尺寸的碎片的留轨特性.结果表明:这次任务产生的碎片将快速坠毁,对空间环境的影响有限.分析结果可以作为参考,更准确的结果有赖于根据实际观测数据进行深入、详细的分析.

Damage Analysis on USA Satellite Intercepted by Navy Missile

Based on experiential models and basic suppositions,breakup characters of collision spacecraft are researched,debris size distribution,area-to-mass ratio distribution and velocity distribution are calculated,orbit lifetimes of various debris are also counted considering survival height and air drag,formulas of survival debris ratio and number are proposed,also the on-orbit characters of debris are analyzed as well.Analysis result indicates that debris from this event will fall and vanish quickly and affect ...
