Abstract
Metal darts are captured either in bonded assembly or in riveted assembly with composite airfoil skins. The darts have a thin fin extending rearward with a dam at its rear end forming a hot air duct on either side of the fin. As hot compressor bleed air is diverted down through the fin duct, heat is transferred forward to the dart leading edge. The fin may contain ripples or other perturbances to improve heat transfer if necessary. Sufficient heat should be transferred to inhibit ice buildup on the final coating that covers the entire airfoil and further provides FOD protection by having a metal leading edge.
