A static variable-pitch propeller is mainly composed of blades, a propeller hub, a propeller disc and a fairing. The roots of the blades and the propeller hub are bonded to form a fixed connection structure, and the propeller hub is provided with a plurality of installation flanges and installed in the propeller disc; one end of the propeller disc is provided with an installation flange which is connected with an external mechanism through bolts and positioning pins, and the other end of the propeller disc is connected with the fairing through bolts. Static pitch changing of the propeller is achieved by replacing pitch changing blocks with different installation angles in the propeller disc. The static variable-pitch propeller has the advantages of being simple in structure, high in efficiency, safe, reliable and the like.

    本发明公开一种静态变距螺旋桨,主要由桨叶,桨毂,桨盘,整流罩组成,桨叶根部与桨毂粘接形成固连结构,桨毂具有多个安装法兰,安装于桨盘中,桨盘一端设置有安装法兰通过螺栓及定位销与外部机构连接,另一端通过螺栓与整流罩连接,通过更换桨盘中不同安装角的变距块实现螺旋桨的静态变距。本发明的静态变距螺旋桨具有结构简单、效率高、安全可靠等优势。
