Title:
DRAG REDUCTION METHOD FOR HYDROKINETIC VERTICAL AXIS TURBINE BLADES AND STRUCTURES
Document Type and Number:
WIPO Patent Application WO/2018/217705
Kind Code:
A3
Abstract:
A vertical axis turbine includes a vertical rotary shaft and turbine blades mechanically coupled to the vertical rotary shaft, each of the turbine blades including curved rounded physical geometries on a leading edge. A method of reducing drag includes improving lift over an air foil design using curved rounded physical geometries on a leading edge of hydrokinetic vertical axis blades that produce channels of high and low pressure.
