Abstract
A system for the generation of electrical power using an improved 600-watt to 900-watt wind turbine system. The system comprises a wind driven generator utilizing an array of uni-directional carbon fiber turbine blades, an air-ducting nose cone, and a supporting tower structure. Additionally, a method of blade fabrication utilizing expanding foam, to achieve improved blade edge strength, is disclosed. The support tower utilizes a compressive coupler that permits standard fence pipe to be joined without welding or drilling.
Claims4
A wind-driven system, for producing electric current, comprising, in combination:
- a) at least one frame adapted to swivel about a substantially vertical axis, comprising
- i) at least one front-portion adapted to extend forwardly into a wind-flow direction and
- ii) at least one rear-portion adapted to extend rearwardly downwind from said at least one front portion;
- b) at least one guide-vane connected to said at least one frame and adapted to guide said at least one frame with respect to the wind-flow direction;
- c) at least one magnetic-field producer, comprising at least one rotor adapted to rotate about at least one rotational axis;
- d) at least one alternator, connected to said at least one frame, adapted to produce electric current, comprising at least one rotor shaft adapted to support said rotor for rotation of said at least one magnetic-field producer;
- e) wherein said at least one magnetic-field producer and said at least one alternator together comprise at least one electric current generator;
- and
- f) at least one airfoil blade, mounted to at least one end of said at least one rotor, adapted to drive said at least one rotor;
- and
- g) at least one nose-cone, extending forwardly from said at least one front-portion, adapted to modify air-flow through said wind-driven means;
- h) wherein said at least one airfoil blade comprises at least one longitudinal axis and at least one skin and at least one interior;
- i) wherein said at least one skin substantially comprises axial reinforcers adapted to reinforce said at least one skin substantially unidirectionally substantially parallel to the at least one longitudinal axis;
- j) wherein said at least one interior comprises at least one foam element comprising at least one material associated with enabling substantial outward pressure on said at least one skin during curing of said at least one foam element.
