Abstract
A blade mounting system for turbine blades of use in vertical axis wind turbines includes a plurality of pairs of vertically spaced mounting units, each coupled to a framework, and between which a respective one of a plurality of turbine blades is pivotally coupled. Each mounting unit pivotally supports one end of a corresponding turbine blade and is linearly displaceable responsive to load forces on the turbine blade. Each mounting unit includes a restraint system that applies a bias force against the linear displacement of the mounting unit and the blade therewith. Each turbine blade has a cambered airfoil with reversible leading and trailing edges.
Claims13
A turbine blade mounting system for supporting each of a plurality of turbine blades between a pair of vertically spaced and rotatably supported frameworks of a vertical axis wind turbine, said turbine blade mounting system including a pair of mounting units respectively pivotally coupled to opposing ends of a corresponding turbine blade, each of said pair of mounting units comprising:
- a carriage displaceably mounted to a corresponding one of said pair of frameworks, said carriage being displaceable along a radially directed path with respect to a rotational axis of said pair of frameworks;
- a pivot receptacle mounted to said carriage and into which an end portion of an axial shaft of said corresponding turbine blade is received;
- and
- a restraint system coupled to said carriage, said restraint system including at least a pair of mechanical energy storage elements coupled between said carriage and said corresponding framework for applying a force to said carriage in opposition to displacement of said carriage being displaced in either of opposing radial directions from an initial position.
