The invention relates to the technical field of space deorbiting, in particular to a space deorbiting damper which comprises a sail film, and the working state of the sail film comprises an unfolded state and a contracted state; when the sail film is in an unfolded state, the sail film is connected end to end to form a circumferentially closed shell with two open ends; a plurality of creases are arranged in the circumferential direction of the sail membrane and divide the sail membrane into a plurality of membrane sheets; when the sail film is in a contraction state, the sail film is folded and contracted to one position in the circumferential direction of the shell through the diaphragm along the folding marks; the guide rail corresponds to the circumferential shape of the shell, and the diaphragm is connected to the guide rail in a sliding mode; and the driver is in driving connection with the diaphragm, and the driver is used for driving the diaphragm to move on the guide rail so as to realize switching of working states of the sail diaphragm. The rail descending function is achieved by switching the working state of the sail membrane, inflation is not needed in the unfolding process of the sail membrane, and the risks such as explosion caused by an inflatable spherical damper are avoided.
本发明涉及空间离轨技术领域,具体涉及一种空间离轨阻尼器,包括:帆膜,帆膜的工作状态包括展开状态和收缩状态;帆膜处于展开状态时,帆膜首尾相接呈周向封闭两端开口的壳体;帆膜周向上设有若干折痕,若干折痕将帆膜分隔成若干膜片;帆膜处于收缩状态时,帆膜通过膜片沿折痕折叠收缩于壳体周向上的一处;导轨,导轨与壳体周向形状相对应,所述膜片滑动连接于导轨上;驱动器,驱动器与膜片驱动连接,驱动器用于驱动膜片在导轨上移动,以实现帆膜工作状态的切换。通过切换帆膜工作状态,实现降轨的功能,帆膜展开过程中无需充气,避免充气球形的阻尼器带来的爆炸等风险。
