The invention discloses a rocket sublevel recovery system. The rocket sublevel recovery system comprises a rocket body, a lift system, an air bag system and a landing pool containing landing liquid. The lift system and the airbag system are arranged on the rocket body; the landing pond is arranged on the ground and/or a ship; after the rocket sub-stages finish stage separation, the lift force system receives an attitude control instruction and controls rolling, pitching and yawing of the rocket body according to the attitude control instruction; in the returning stage, after the height of the rocket sub-stage meets the working condition of the air bag system, the air bag system receives and executes the inflation instruction, multiple air bags in the air bag system are inflated to preset pressure, and returning preparation work is completed; in the landing returning stage, the rocket body makes contact with landing liquid in the landing pool, the rocket body floats on the landing liquid through the multiple air bags, and landing and recovery are completed. The method has the technical effects that impact during rocket sublevel landing is reduced, the rocket body is prevented from sinking to the bottom, the landing precision is high, the impact is small, and the integrity of core components of the rocket body can be guaranteed.

    本申请公开了一种火箭子级回收系统,包括:箭体、升力系统、气囊系统和盛装有着陆液体的着陆池;升力系统和气囊系统均设置于箭体上;着陆池设置于地面和/或船上;火箭子级完成级间分离后,升力系统接收姿控指令,并根据姿控指令对箭体的滚转、俯仰和偏航进行控制;在返回阶段,当火箭子级的高度满足气囊系统的工作条件后,气囊系统接收并执行充气指令,将气囊系统中的多个气囊充气至预定压力,完成返回准备工作;在返回着陆阶段,箭体与着陆池内的着陆液体接触,并通过多个气囊使箭体漂浮于着陆液体上,完成着陆和回收。本申请具有降低火箭子级着陆时的冲击和避免箭体沉底、着陆精度高、冲击小,以及能够保证箭体核心部件的完整性的技术效果。
