Rotor blade for tidal current power turbine and manufacturing method of the same

摘要

The present invention relates to a rotor blade for a tidal power turbine and a manufacturing method thereof, comprising: a rotor hub portion coupled to a rotary shaft of a turbine, a blade root portion symmetrically coupled to the rotor hub portion to support a blade, and the blade root portion A plurality of blade blocks are sequentially coupled to the blade body portion to form an airfoil shape of the blade, and a blade tip portion coupled to the outermost portion of the blade body portion to form a blade tip. Therefore, the present invention divides the blade body into a plurality of block shapes and assembles the blades, which enables mass production and excellent moldability, and provides an effect of enabling the formation of sophisticated airfoil curved surfaces.
