AIRFOIL DEVICES, LEADING EDGE COMPONENTS, AND METHODS OF MAKING

摘要

In a method of making a leading edge component for an airfoil device a first elongate sheet is provided and has a shape substantially conforming to a surface on one of a suction side or a pressure side of an airfoil. A second elongate sheet is provided and has a shape substantially conforming to a surface on the other of the suction side or the pressure side of the airfoil. The elongate sheet can be welded together at least along respective elongate edges thereof, in such a way as to form a leading edge base structure comprising a weld extending the length of the elongate sheets. Material deposits can be provided onto an outer surface of the leading edge base structure in such a way as to substantially cover the weld, whereby the leading edge component is formed.
