摘要： A leading edge construction for reducing drag on an airfoil, the construction includes a relatively thin solid plate extending forwardly from the air foil, the plate having an exposed top surface and an exposed bottom surface, and a relatively sharply radiused forward edge forming the leading edge of the air foil. The construction further includes slots adjacent to the top and bottom surfaces of the plates for injecting coolant over the top and bottom surfaces of the plate, toward the leading edge, to provide active cooling of the plate for removing stagnant heat lead. The method for reducing drag on a air foil according to this invention includes the steps of providing a relatively thin solid plate extending forwardly from the air foil; the plate having a relatively sharply radiused forward edge forming a leading edge for the air foil, and exposed top and bottom surfaces for cooling; injecting coolant over the top and bottom surfaces of the plate, toward the forward edge; entraining the coolant over the surfaces to actively cool the edge and remove the static heat load.
