HIGH-EFFICIENCY UNITED COMPOSITE TURBINE BLADE

摘要

The present invention relates to a high-efficiency integrated composite turbine blade using a tidal power, comprising: symmetrical wing portions on both sides; a wing-integrated hub structure penetrated by a joining hole on the center; and a hub coupling body coupled to the joining hole of the hub structure while penetrating. The hub coupling body comprises: a lower coupling body coupled to the joining hole of the hub structure while penetrating, to rotate together with the hub structure; and an upper coupling body extrapolated to the top of the lower coupling body and coupled to the top end surface of the hub structure, thereby maintaining sufficient structural strength, integrating the wing portions and hub, and enhancing the efficiency of the turbine.
