【摘要】 文章介绍了哈尔滨工业大学空间碎片高速撞击研究中心"十二五"期间发布的空间碎片环境工程模型(SDEEM 2015)。该模型可实现LEO空间碎片环境描述,空间碎片撞击风险评估以及地基探测结果仿真,还可输出LEO航天器不同轨道位置处空间碎片撞击通量随撞击方位角、撞击速度及碎片尺寸的分布规律,地基探测设备探测区域内空间碎片空间密度及通量的分布情况等信息。SDEEM 2015适用轨道高度范围为200~2000 km,时间范围为1959年—2050年,所考虑的空间碎片来源包括解体碎片、Na K液滴、固体火箭发动机喷射物、溅射物和剥落物。更多还原

【Abstract】 Based on the urgent requirements to establish our own engineering model, the Space Debris Environment Engineering Model(SDEEM 2015) is developed by the Hypervelocity Impact Research Center of Harbin Institute of Technology. SDEEM 2015 provides a description of the space debris environment in the LEO region. The software is designed to be a space debris risk assessment tool for the LEO space activity operations as well as the debris measurements and observations. SDEEM 2015 is valid in the altitude range between 200 and 2000 km, the time range from the year 1959 to 2050. The source data includes the fragments, the Na K drops, the SRM(Solid Rocket Motor Firings) slag and dust, ejecta and paint flakes.更多还原
