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 lift component force, as well as a reduced drag component force. The airfoil may be any type of airfoil, such as a rotating cylinder. The vane-airfoil combination may also include a fore-body and an after-body for reducing the pressure along an upper portion of the airfoil.
