Title:
ROTOR BLADE AND HORIZONTAL WATER TURBINE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2019/049902
Kind Code:
A1
Abstract:
Provided is a rotor blade that is configured so as to gather a fluid from both a blade root and a blade end of a blade toward the center along the length direction of the blade, allow a large quantity of the fluid to pass toward the trailing-edge direction, and raise rotation efficiency through a reaction to the passage of the fluid. In a front view, the chord length is gradually increased from the blade root 2 toward the blade end, and with a maximum-chord-length section 4 as a reference point, the blade end serves as a forward-inclined part 6 that is inclined forward, and a surface that is flat in the chord direction is inclined toward a rear surface from a leading edge 7 to a trailing edge 8. In a side view, the thickness is gradually increased from a main section 5 to the distal-end part of the blade root 2 to form a thick-base section.
