Abstract

The invention discloses a fan blade with stiffeners and a manufacturing method thereof. The fan blade comprises a plurality of groups of stiffeners, and the stiffeners are arranged on the upper side, the lower side or both sides of the thickness direction of a core material of the fan blade and comprise a plurality of layers of sheets, and each layer of sheet forms staggered layers along the chordwise direction and the spanwise direction of the fan blade. And the reinforcing strip, a core material of the fan blade and other cloth layers are poured and cured together.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a fan blade with reinforcing strips and a manufacturing method thereof. Background technique [0002] A wind generator includes a tower, a nacelle rotatably connected to the tower and supporting a hub. Two or more fan blades are arranged on the hub, wherein the fan blades drive the rotor arranged in the hub to rotate around the axis under the action of wind force, wherein the rotation of the rotor of the generator relative to the stator will generate electric energy. It can be seen that the fan blade is a key component in the fan. At present, the manufacturing cost of fan blades is high due to various factors such as high-cost materials and complex structures, and the manufacturing cost of fan blades often determines the cost competitiveness of a fan. [0003] In the wind turbine blade structure, the key components are main girder, trailing edge girder, web and shell. Among...
