ABSTRACT:
An airfoil structure for use in an axial flow turbomachine is disclosed. Various construction details which improve the durability, integrity and the cooling effectiveness of the structure are shown and a method for fabricating the structure is developed. The tip of the structure is closed by a tip cap, and in one embodiment, a ductile material is deposited between the tip of the structure and the tip cap to prevent the leakage of cooling medium.
