ABSTRACT:
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.
