The invention discloses an underwater vehicle high-speed water entry buffer head cap adopting a multi-bionic buffer structure, which is characterized in that a filler I is filled between an inner-layer thin-wall shell and an outer-layer shell in a wheat stalk-imitating structure housing, a plurality of through holes are formed in the outer-layer shell, and a plurality of fiber pipes are embedded in the filler I; the bidirectional mantis-shrimp-imitating sine structure buffer layer is composed of a plurality of clamping plates which are arranged at intervals along the rotation center line of the wheat stem-imitating structure housing and are of a bidirectional mantis-shrimp-imitating sine structure, and filler II is filled between every two adjacent clamping plates and between the clamping plate closest to the head and the head of the inner-layer thin-wall housing; the coconut tree and cobweb imitating composite structure buffer layer is composed of a plurality of stacked circular truncated cone assemblies, and third fillers are filled between the cobweb imitating structures in the circular truncated cone assemblies and the inner wall of the circular truncated cone thin-walled tube and all cavities in the cobweb imitating structures. According to the invention, a multi-bionic buffer structure is adopted to absorb impact energy borne by the underwater vehicle when the underwater vehicle enters water layer by layer, and a buffer protection effect on the underwater vehicle is achieved.
本发明公开了采用多重仿生缓冲结构的水下航行器高速入水缓冲头帽,其仿小麦茎秆结构罩壳中内层薄壁壳体与外层壳体之间填充填充物一,外层壳体开设多个通孔,填充物一内嵌有多个纤维管;双向仿螳螂虾正弦结构缓冲层由沿仿小麦茎秆结构罩壳的回转中心线间距布置且形状为双向仿螳螂虾正弦结构的多个夹板组成,每相邻两个夹板之间以及最靠近头部的夹板与内层薄壁壳体头部位置之间均填充填充物二;仿椰子树与蛛网复合结构缓冲层由层叠的多个圆台组件组成,圆台组件中仿蛛网结构与圆台薄壁管内壁之间以及仿蛛网结构内部的各空腔内均填充填充物三。本发明采用多重仿生缓冲结构逐层吸收水下航行器入水时受到的冲击能量,对水下航行器起缓冲保护作用。
