Abstract

A composite propeller blade structure includes at least a rotation shaft and a rotation surface on which plural blades are formed, and characterized in that: each of the blades is composed of plural blade units; and in the equivalent radius cross section of each of the blades, the installed location of a front edge of the blade unit at the downstream is defined as following: in the rotation axial direction, which is located behind a rear edge of the adjacent blade unit at the upstream, and the maximum distance thereof is not greater than 25% of the radius of the adjacent blade unit at the upstream; and in the circumferential direction, located at the pressure surface side defined on the nose-trail line of the adjacent blade unit at the upstream, and the maximum range thereof is not greater than (360° / 2N), wherein N is the quantity of the blades.

Description

technical field [0001] The invention relates to a propeller blade structure for working in liquid fluid, in particular to a composite propeller blade structure. Background technique [0002] The propeller blade structure is an important equipment for human industry, including propellers of ships and submarines, which are generally driven by the propeller blade structure. Therefore, improving the efficiency of the propeller blade structure is very important for cost control, work efficiency or energy saving. [0003] A typical propeller blade structure must have at least one rotating shaft and a rotating side corresponding to the rotating shaft, and a plurality of identical fan blades are arranged on the rotating side. The existing technology is to adjust the size and angle of the fan blade to obtain the maximum performance, but the obtained performance has reached the bottleneck and there is no further significant improvement. [0004] Therefore, the present invention prop...
