The semi-empirical ballistic limit equations （BLEs）defining the protection capability of the shield system are given, and the shielding performance is also discussed. The corrugation stuffed shield （CKS） is more effective than stuffed Whipple shield for M/OD protection, and its shielding performance will be improved significantly as increasing the impact angle. Orbital debris up to 1 cm in diameter can be shielded effectively as increasing the impact angle to 25° at the corrugated angle of 30°. The results are significant to spacecraft design.展开更多

The computing resolution of MODRAS has been verified by both the three generic spacecraft geometries of inter agency debris committee （IADC） and similar foreign software such as BUMPER, ESABASE, and MDPANTO. The results show that the system is fit well with the computing results of the foreign software. Typical applications of the system are also presented, including a manned spacecraft and a space shuttle.展开更多
