| 摘 要： | 为了评估航天器遭遇空间碎片碰撞风险,基于GUI技术自主开发了一套空间碎片碰撞风险评估系统(MODRAS).并以特定轨道航天器为应用实例进行了风险评估,得到了空间碎片通量分布、航天器暴露面积、航天器遭遇的碰撞数等数据.结果表明,航天器遭遇空间碎片碰撞的概率与其运行轨道高度、倾角以及碎片大小等参数有关;改变航天器飞行路线及运行姿态可有效减少空间碎片的碰撞风险.

| Abstract: | A GUI based meteoroid and orbital debris risk assessment system(MODRAS) is developed for assessing risks to spacecraft from meteoroid and debris impact.Instance a spacecraft as an example for M/OD risk assessment is conducted.The distribution of debris flux,exposed area of spacecraft and impact data are obtained.The results show that the relative impact possibility for a spacecraft depends on the spacecraft's altitude and orbital inclination,as well as debris size.Changes in shuttle mission operations,flight rules,and flight planning were adopted to reduce meteoroid and debris risks. |
