Wind-driven rotor assembly
Patent
·
OSTI ID:7080646
A wind-driven rotor for generating power has a central normally vertical column mounted in a base structure for rotation about the column axis. In the preferred form of the invention, a plate is secured to the top of the column perpendicular to the axis of rotation, and functions both as an aerodynamic end plate and as a bracket supporting a group of articulating airfoils. These are rotatable about a pivot connection to the end plate with freedom of movement within a limited sector of articulation providing driving and feathering airfoil positions. The airfoils are preferably triangular, with an apex downward, and pivotally connected to a member fixed with respect to the column at a position relatively close to the column axis, so that one side of the triangular configuration approaches parallelism with the column.
