TURBINE ENGINE COMPONENT AND METHOD OF MANUFACTURING TURBINE ENGINE COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a microcircuit (32) for cooling a component (12) of a turbine engine. SOLUTION: The turbine engine component (12) has an aerofoil portion (10) including a suction surface (14). The component is provided with the cooling microcircuit (32) embedded in a wall structure (34) forming the suction surface. The cooling microcircuit has at least one cooling film hole (36) positioned in front of a gage point for creating a flow of a cooling fluid over the outer surface of the suction surface which flows past a throat point (38). The cooling microcircuit is formed using a high fusing point metal core technology. COPYRIGHT: (C)2007,JPO&INPIT
