A vane-airfoil combination for shifting forces associated with an airfoil. The vane-airfoil combination includes an airfoil moving through a fluid, such as air. A plurality of vanes is positioned in front of the airfoil to divert the path of the fluid to the airfoil. The change in the path of the fluid rotates the forces associated with the airfoil in relation to the original path of the fluid. Specifically, a lift force is rotated to provide a thrust component force, as well as a lift component force. In addition, a drag force is rotated to provide a li...
[ What is claimed is:] [1.] An apparatus for altering a flow of a fluid stream around an airfoil, said apparatus comprising:an airfoil having an orientation angle relative to the horizon and an angle of attack relative to the fluid stream; anda plurality of vanes movably mounted in front of the airfoil which divert the fluid stream to change the angle of attack of the airfoil.
