A passive porosity management device and process for an airfoil which provides a mechanism and method for controlling and modifying the lift, drag and flow field characteristics on an airfoil through the controlled seepage and transference of air utilizing passive porosity through one or more regions of an airfoil and into, and out of, one or more plenum cavities disposed in the interior portion of the airfoil.
[ I claim:] [1.] A passive porosity management device for an airfoil, the airfoil having an outer surface and an interior surface, the passive porosity management device comprising:an outer porous skin region on the outer surface of the airfoil, the outer porous skin region having a plurality of perforations therethrough;a plenum cavity disposed in the interior of the airfoil in fluid communication with corresponding outer porous skin regions of the airfoil;means for precluding fluid communication, and the seepage and transference of air, through the out...
