COMPOSITE AIRFOILS HAVING LEADING EDGE PROTECTION MADE USING HIGH TEMPERATURE ADDITIVE MANUFACTURING METHODS

摘要

Composite airfoils including a leading edge, and a near net shape metal leading edge protective strip operably connected to the leading edge, the protective strip made by providing a high temperature additive manufacturing device; providing a tooling system including a mandrel; a metallic cladding; and at least one cooling channel applying a metallic deposit to the mandrel having the metallic cladding using the high temperature additive manufacturing device; and concurrently removing heat from the mandrel using the at least one cooling channel.
