DETECTION OF BLOCKAGE IN INTERNAL PASSAGES OF GAS TURBINE ENGINE COMPONENTS
First Claim
1. A method of forming a component comprising:
- placing a core into a mold and pouring a component material around the core;
allowing the component material to solidify, and then removing the core from within said material, leaving a component having at least a first and a second cavity formed by said core;
moving a first filler material into the first cavity, and moving a second filler material into the second cavity; and
inspecting said component for the presence of an apparent residual core within said first cavity and said second cavity, and identifying the location of the apparent residual core from said core based upon an identification of whether the location of the apparent residual core is in the first or second filler materials.

Abstract
A method of forming a component includes the steps of placing a core into a mold and pouring a component material around the core. The component material is allowed to solidify. The core is then removed from within the material, leaving a component having at least a first and a second cavity formed by the core. A first filler material is moved into the first cavity, and a second filler material is moved into the second cavity. The component is inspected for the presence of an apparent residual core within the first cavity and the second cavity. The location is identified of the apparent residual core from the core based upon an identification of whether the location of the apparent residual core is in the first or second filler materials. A method of inspecting a component formed by investment casting is also disclosed.

21. A method of inspecting an article formed by investment casting using a ceramic inner core, comprising the steps of:
-
receiving the article with the ceramic inner core removed, the article having a first and a second passage formed by the ceramic inner core; moving a first filler material into the first passage, and moving a second filler material into the second passage; and inspecting the article for the presence of an apparent residual core within said first passage and said second passage, and identifying the location of the apparent residual core from said core based upon an identification of whether the location of the apparent residual core is in the first or second filler materials.
