Abstract:
1. An airfoil comprising: a frontal surface that leads through a fluid; an first surface relating with said frontal surface that receives fluid flow thereon; a second surface opposite said first surface and relating with said frontal surface, said second surface also receiving fluid thereon; a airfoil tip relating to said first and second surfaces that releases fluid from said airfoil; and at least one fluid flow regulator featured and operable with said first surface, said fluid flow regulator comprising a leading edge, a trailing edge, and a pressure recovery drop extending between said leading and trailing edges to form a down step, said pressure recovery drop comprising at least one drop face of a calculated height formed therein, said fluid flow regulator functioning to optimize air flow, reduce separation of said fluid over said first surface of said airfoil, and reduce induced noise, wherein said fluid flow regulator is removably attached to said first surface.
