The invention provides a spacecraft protection system and method, and belongs to the technical field of aerospace, the spacecraft protection system is applied to a spacecraft, and the spacecraft protection system comprises a space debris early warning device, a protection screen and a driving device; the protective screen is arranged on the outer cabin wall of the spacecraft, the space debris early warning device is electrically connected with the driving device, and the driving device is in driving connection with the protective screen; the protection screen is made of a shape memory polymer composite material, the protection screen is of a paper folding structure and comprises a folded state and an unfolded state, in the spacecraft launching process, the protection screen is in the folded state, and after the spacecraft reaches a running orbit, the protection screen is converted into the unfolded state from the folded state by applying external stimulation. According to the spacecraft protection system provided by the invention, active defense can be realized according to the trajectory of the space debris, and the active protection capability of the protection screen is improved, so that the spacecraft is comprehensively protected, and the spacecraft is prevented from being damaged.

    本发明提供了一种航天器防护系统及防护方法,属于航空航天技术领域,航天器防护系统应用于航天器,包括空间碎片预警装置、防护屏和驱动装置;防护屏设置于航天器的外舱壁上,空间碎片预警装置与驱动装置电连接,驱动装置和防护屏驱动连接;防护屏由形状记忆聚合物复合材料制得,防护屏的结构为折纸结构,包括收拢状态和展开状态,在航天器发射过程中,防护屏为收拢状态,当航天器到达运行轨道后,通过施加外界刺激将防护屏从收拢状态转换为展开状态。本发明提供的航天器防护系统能够根据空间碎片的轨迹实现主动防御,提高了防护屏的主动防护能力,从而对航天器进行全方位的保护,避免航天器受到损伤。
