The embodiment of the invention provides a large-opening-angle head configuration for an underwater vehicle and the underwater vehicle, the head configuration is of a left-right symmetrical and up-down asymmetrical structure, and the head configuration comprises a head spherical section, a middle cylindrical section, a curved surface transition section and a rear cylindrical section in the axis direction. The head spherical section is of a hemispherical structure with the radius being R2, and the radius of the middle cylindrical section is the same as that of the head spherical section. The rotation axis of the middle cylindrical section and the rotation axis of the rear cylindrical section are located on the same symmetric plane. The curved surface transition section comprises N angle section curves, the rotation axis of the middle cylindrical section serves as a reference, the included angle between the sections is theta, the angle sections are evenly distributed in the circumferential direction, and theta = 180/N. And the projection of each angle section curve on the corresponding angle section is a B spline constructed by control points. According to the technical scheme, the acoustic sector, the fluid performance and the structural layout can be considered, and the underwater comprehensive performance of the underwater vehicle is improved.
本发明实施例提供一种水下航行器用大开角头部构型及水下航行器,所述头部构型为左右对称、上下非对称结构,其从轴线方向上,包括:头部球面段、中部圆柱段、曲面过渡段和后部圆柱段。头部球面段为半径为R2的半球结构,中部圆柱段的半径与头部球面段半径相同。中部圆柱段的回转轴线与后部圆柱段的回转轴线同位于对称平面。曲面过渡段包括N个角度截面曲线,以中部圆柱段的回转轴为参考,各截面间的夹角为θ,各角度截面在圆周方向呈均匀分布,θ=180/N。所述各角度截面曲线在对应角度截面上的投影为控制点构造的B样条。本发明技术方案,能够兼顾考虑声学扇面和流体性能和结构布局,提升水下航行器水下的综合性能。
