Title:
WIND DRIVEN POWER GENERATOR AND APPLICATIONS OF SAME
Document Type and Number:
WIPO Patent Application WO/2009/149016
Kind Code:
A3
Abstract:
A wind driven generator includes a rotor disposed in a cylindrical duct and supported by a frame for rotation in response to wind flowing through the duct. The rotor includes plural circumferentially spaced paralleled rotor blades supported for rotation about a generally horizontal axis. Each blade is supported for pivotal movement to change blade pitch, angle of attack or camber as the rotor rotates. A pitch or camber control motor, self- governing wind vane mechanism, or governing mechanism is operable to move a circular cam to vary blade pitch or camber to control rotor speed. Electric power generators are connected to opposite ends of the rotor at respective power output or drive shafts.
