Title:
POWER GENERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/074005
Kind Code:
A3
Abstract:
The invention relates to a renewable energy power generating device for converting wind and/or water-flow energy into useable electrical power. The power generating device includes a support structure (112 A) rotatable about a first axis of rotation (C), a plurality of aerofoil blades rotatably mounted on the support structure (112 A) and free to rotate relative thereto about a second axes of rotation (Q) substantially parallel to and radially spaced from the first axis of rotation (C), and a means (162, 166, 168} for actuating the aerofoil blades (114) between first (114 A) and second (114 B) reflexed camber aerofoil section conditions such that the aerofoil blades (114) are freely rotatable to automatically set an angle of attack relative to a fluid flow direction (D) thereby to generate a lift force thereover and transmitting a torque to the support structure (112 A) to drive it through a repeating 360 degree rotary cylce.
