The invention provides a rocket sublevel recovery method and system, and belongs to the technical field of rocket sublevel recovery. The rocket sublevel recovery method provided by the invention comprises the following steps that a rocket sublevel enters a return orbit after being separated from a rocket body; in an atmospheric layer, grid fins are adopted to control the flight and attitude of therocket sublevel; the rocket sublevel is decelerated through a controllable propulsion deceleration system and a parachute system; and the rocket sublevel located in air is grabbed through an aircraft. In the rocket sublevel recovery method, after the rocket sub stage is separated, in the landing process of the rocket sublevel, the rocket sublevel in the air is grabbed through the aircraft so as to prevent the rocket sublevel from losing stability, tilting to overturn or exploding in the landing process, safe landing of the rocket sublevel is ensured, and it is ensured that the rocket sublevelcan be reused.

    本发明提供的一种火箭子级回收方法及系统,属于火箭子级回收技术领域,本发明提供的火箭子级回收方法,包括以下步骤:火箭子级和火箭本体分离后进入返回轨道;在大气层内,采用栅格翼控制火箭子级的飞行和姿态;火箭子级通过可控推进减速系统和降落伞系统进行减速;通过飞行器抓取位于空中的火箭子级;本发明的火箭子级回收方法中,当火箭子级分离后,当火箭子级在降落的过程中,通过飞行器抓取空中的火箭子级,防止火箭子级在着陆的过程中发生失稳、倾斜颠覆或者爆炸的情况,保证火箭子级的安全着陆,保证其能够重复使用。
