ABSTRACT:
A passive porosity airfoil lift management device employed on a leading edge region of said airfoil whereby the lift on said airfoil may be varied and controlled by passively transferring air pressure between the upper surface and lower surfaces of said leading edge region of the airfoil through upper and lower porous skin regions, upper and lower plenum cavities disposed in said airfoil, and controllably monitoring and regulating said passive air pressure transference with at least one valve and a microprocessor.
