The invention discloses an external air bag type combined load reduction device and method for high-speed water entry of a navigation body. The external air bag type combined load reduction device structurally and mainly comprises a telescopic load reduction rod, an air bag load reduction device and a buffer module. The telescopic load-reducing rod comprises a disc-shaped cavitator, a cylindrical rod and a base, the tail base is matched with the navigation body through a stepped hole, the air bag load-reducing device comprises a foldable air bag and an air generating device, the air bag is arranged on the side wall of the cylindrical rod, and the buffer module is arranged in the stepped hole. After the navigation body enters water at a high speed, the load reduction rod shrinks, the air bag is inflated and expanded, the load reduction module compresses and absorbs energy to reduce the impact load of the navigation body entering water, the load reduction rod shrinks completely after the air bag falls off, and the follow-up movement of the navigation body is not affected. Through an external airbag type combined load reduction mode, the high-speed water entry stability of the navigation body is improved, and safe water entry of the navigation body is achieved.

    本发明公开了一种航行体高速入水外置气囊式组合降载装置及方法,其结构主要包括可伸缩降载杆,气囊降载装置及缓冲模块。可伸缩降载杆包括圆盘型空化器、圆柱杆和底座,尾部底座通过阶梯孔与航行体相配合,气囊降载装置包括可折叠气囊和气体发生装置,气囊安置在圆柱杆侧壁,缓冲模块安置在阶梯孔内部。航行体高速入水外置气囊式组合降载结构入水后,降载杆收缩,气囊充气膨胀,降载模块压缩吸能减小航行体入水冲击载荷,气囊脱落后降载杆收缩完全,不影响航行体后续运动。本发明通过外置气囊式组合降载的方式,提高航行体高速入水的稳定性,实现航行体安全入水。
