Abstract
A reversible airfoil generally wing-like in shape comprising at least two spaced apart rigid spars having at least two slots therethrough, bars projecting through the slots in each rigid spar, each end of each bar attaching to a flexible slat, and a common flexible movable skin adjacent the flexible slats thereby covering same to form a reversible airfoil. A series of the rigid spars and attending parts when covered by a common flexible skin and adapted to fit on a beam provides a unique sail for a sailboat. Additionally, a series of the rigid spars and attending components when covered by a common flexible skin and vertically mounted on a rotatable frame provides a reversible lift airfoil for a wind-powered generator.
Claims15
A reversible airfoil having a tapered and shaped configuration comprising:
- at least two spaced apart rigid spars having in each of said rigid spars,
- at least two slots therein, said slots of sufficient size to permit bars to project therethrough, each end of said bar attaching to,
- flexible slats parallel to said rigid spars, and
- a flexible movable skin covering the outer surfaces of said flexible slats, said bars moving in and through said slots in said rigid spars to allow said flexible slats and said skin to move in relation to said rigid spars in response to wind impacting said airfoil and thereby creating a lifting action in said airfoil.
A sail for a sailboat comprising:
- a plurality of spaced apart rigid spars having a plurality of slots therein of sufficient size to permit,
- bars to project therethrough and attach to,
- a plurality of spaced apart flexible slats parallel to said rigid spars,
- a flexible, movable skin covering the outer surfaces of said flexible slats and joining same,
- a beam projecting through an opening in a forward area of each of said rigid spars, said beam functioning as a mast for said sailboat, and
- a system of ropes and pulleys attached to said sail and said beam to raise and lower said sail,
- said bars moving in and through said slots in said rigid spars to allow said flexible slats and said skin to move in relation to said rigid spars in response to wind impacting said sail and thereby creating a lifting action in said sail.
A wind-powered generator comprising a plurality of vertically mounted panels secured to a frame and capable of rotating in response to the force of wind impacting thereon, said vertically mounted panels comprising:
- a plurality of spaced apart rigid spars having a plurality of slots therein of sufficient size to permit,
- bars to project therethrough and attach to,
- a plurality of spaced apart flexible slats parallel to said rigid spars, and
- a flexible, movable skin covering the outer surfaces of said flexible slats and joining same,
- said bars moving in and through said slots in said rigid spars to allow said flexible slats and said skin to move in relation to said rigid spar in response to wind impacting said panels and thereby creating a lifting action in said panel resulting in said panels rotating and generating power to a device connected to said wind-powered generator.
