DETECTION OF BLOCKAGE IN INTERNAL PASSAGES OF GAS TURBINE ENGINE COMPONENTS

A method of forming a component (100) includes the steps of placing a core (110) into a mold (118,120) and pouring a component material (122) around the core (110). The component material (122) is allowed to solidify. The core (110) is then removed from within the material (122), leaving a component...

Zusammenfassung:	A method of forming a component (100) includes the steps of placing a core (110) into a mold (118,120) and pouring a component material (122) around the core (110). The component material (122) is allowed to solidify. The core (110) is then removed from within the material (122), leaving a component (100) having at least a first (102) and a second (104) cavity formed by the core (110). A first filler material (128) is moved into the first cavity (102), and a second filler material (126) is moved into the second cavity (104). The component (100) is inspected for the presence of an apparent residual core (132,138) within the first cavity (102) and the second cavity (104). The location is identified of the apparent residual core (132,138) from the core (110) based upon an identification of whether the location of the apparent residual core (132,138) is in the first (128) or second (126) filler materials.
