摘　　要：不同于目前可重复使用运载火箭着陆腿回收方案,提出一种基于地面拦阻原理的火箭垂直着陆回收机构方案,在火箭垂直着陆下降过程中,利用地面拦阻索和阻尼器的综合作用实现火箭制动回收。通过仿真分析和原理样机验证,在落点正常、水平偏置和旋转状态下,地面拦阻机构均能实现对运载火箭的拦阻回收,火箭结构承受的过载和冲击较小,姿态稳定。研究表明,拦阻回收机构能够实现箭体安全可控回收。Different from the current reusable launch vehicle landing leg recovery scheme,this paper proposes a rocket vertical landing recovery mechanism based on a ground arresting scheme.In the process of rocket vertical landing and descending,the comprehensive action of ground arresting cable and damper is used to accomplish rocket braking recovery.Through the simulation analysis and the verification of the principle prototype,the ground arresting mechanism complete the arresting and recovering of the launch vehicle under the conditions of normal landing point,horizontal offset and rotation,the overload and impact on the rocket structure are small,and the attitude is controllable.The research shows that the arresting recovery mechanism realizes safe and controllable recovery of the rocket body structure.
