CN209214656U 一种叶片组合式仿生导流罩 有权 转让

一种叶片组合式仿生导流罩
摘要：
本实用新型属于水下声学设备技术领域，公开了一种叶片组合式仿生导流罩，包括基础导流罩和叶片，叶片具有一个或两个或多个连接部，每个连接部与基础导流罩连接或与一个或两个或多个连接部连接。本技术方案通过普通透声基础导流罩表面连接多个较小尺寸的叶片，叶片两两相连形成导流罩，基片较小，便于加工制作；在使用过程中受水流冲击产生的振动轻微，不会产生明显的流噪声；具有光滑的表面，能减少与水流的摩擦力，不会产生明显的流噪声；叶片可拆卸安装，可重复利用。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model belongs to the technical field of underwater acoustic equipment, and discloses a blade combined type bionic air guide sleeve which comprises a basic air guide sleeve and blades, eachblade is provided with one or two or more connecting parts, and each connecting part is connected with the basic air guide sleeve or connected with one or two or more connecting parts. According to the technical scheme, the blades with small sizes are connected to the surface of the common acoustic transmission basic fairing, every two blades are connected to form the fairing, the substrate is small, and machining and manufacturing are convenient; in the using process, vibration generated by water flow impact is slight, and obvious flow noise cannot be generated; due to the smooth surface, the friction force with water flow can be reduced, and obvious flow noise cannot be generated; the blades are detachably installed and can be repeatedly used.
