The invention relates to an underwater bionic anti-drag pressure-resistant shell which comprises a cylindrical shell body, an end socket, a convex hull structure and a concave pit structure. The sealing heads are correspondingly and fixedly connected to the two sides of the cylindrical shell respectively; the convex hull structures and the concave pit structures are evenly distributed on the outer circumferential surface of the cylindrical shell in the axial direction in a row and staggered circumferential mode. Every two adjacent rows of convex hull structures and concave pit structures correspond to each other and are uniformly spaced. Through the existence of the convex hull and concave pit structures, fluid around the surface of the shell can be disturbed, so that fluid resistance borne by the submersible when the submersible sails in a deep sea or underwater is greatly reduced, and the submersible has fluid dynamic characteristics, the utilization rate of space in the shell, good mechanical characteristics and passenger comfort; the maneuverability, the safety, the carrying capacity and the diving time of the submersible are comprehensively improved, meanwhile, the weight of the pressure-resistant shell can be reduced, the reserve buoyancy of the pressure-resistant shell is increased, and the machining and manufacturing difficulty and cost are reduced.
本发明涉及一种水下仿生减阻耐压壳体,包括圆柱壳体、封头、凸包结构和凹坑结构;所述封头分别对应固接在圆柱壳体的两侧;所述凸包结构和凹坑结构分别延轴向成列且相互交错的圆周均布在圆柱壳体的外圆周表面;相邻两列凸包结构与凹坑结构之间相互对应且间隔均匀。本发明通过凸包与凹坑结构的存在,可扰动壳体表面周围的流体,从而大幅降低潜水器在深海或水下航行时受到的流体阻力,具有流体动力学特性、壳内空间利用率、良好的力学特性以及乘员舒适性,有利于综合提升潜水器的机动性、安全性、载运能力和下潜时间,同时还可减轻耐压壳体重量,增大耐压壳体的储备浮力,并降低加工制造难度和成本。
