The device comprises a landing plate, a recovery platform, a magnetic attraction assembly and a supporting column, a rocket lower assembly falls into an avoiding hole of the recovery platform, at the moment, the magnetic attraction assembly works and generates a magnetic pole, and at the moment, the magnetic pole generated by the magnetic attraction assembly is controlled to be the same as the magnetic pole of the landing plate; the recovery platform generates certain reverse thrust on the whole rocket by utilizing the principle that like poles repel away from each other, recovery falling operation can be completed when a rocket engine is shut down, the requirement for variable thrust of the rocket is lowered, and the impact degree generated by rocket landing is reduced. The magnetic pole assembly can be operated to change the magnetic pole to achieve the state of opposite pole attraction with the landing plate, small-amplitude bounce or displacement of the whole rocket is reduced through magnetic pole attraction force when a rocket engine is shut down, the recovery landing stability is improved, and the reliability of reusing of the rocket is improved.

    本发明公开了一种用于液体火箭回收的装置,其包括着陆板、回收平台、磁吸组件以及支撑柱,火箭下部组件落下到回收平台的避让孔内,此时磁吸组件工作并产生磁极,此时控制磁吸组件产生的磁极与着陆板的磁极相同,并利用磁极同性相斥的远离,实现回收平台对火箭整体产生一定的反推力,火箭发动机关机就可以完成回收下落的操作,降低对火箭可变推力的要求,降低火箭着陆产生的撞击程度,在火箭发动机关机回收下落的过程中,可以操作磁极组件改变磁极,达到与着陆板异性相吸的状态,在火箭发动机关闭的时候通过磁极吸附力降低火箭整体的小幅跳动或者位移,提高回收着陆的稳定性,提高火箭再次使用的可靠性。
