Abstract
A component for a gas turbine engine according to an exemplary aspect of the present disclosure includes, among other things, a body portion, a cooling circuit disposed within the body portion and including at least a first cavity, a core in fluid communication with the first cavity, and an exit surface that extends through an exterior surface of the body portion. At least one surface indicator is visible near the exit surface.
Claims20
A component for a gas turbine engine, comprising:
- a body portion;
- a cooling circuit disposed within said body portion and including at least a first cavity, a core in fluid communication with said first cavity, and an exit surface that extends through an exterior surface of said body portion;
- and
- at least one surface indicator is formed at said exit surface and visible near said exit surface, wherein said at least one surface indicator is visible near at least one of a leading edge, a trailing edge, an inner diameter and an outer diameter of a discharge opening of said exit surface.
A method for determining whether a component is within an acceptable manufacturing tolerance, comprising the steps of:
- inspecting the component to determine whether a surface indicator is visible near an exit surface of the component after the component has been manufactured, wherein said surface indicator is visible near at least one of a leading edge, a trailing edge, an inner diameter and an outer diameter of a discharge opening of said exit surface;
- inspecting the component to determine whether a second surface indicator is visible near said exit surface of the component after the component has been manufactured, wherein said second surface indicator is visible near at least one of said leading edge, said trailing edge, said inner diameter and said outer diameter of said discharge opening, wherein said surface indicator is located at said leading edge of said discharge opening of said exit surface and said second surface indicator is located at said trailing edge of said discharge opening;
- and
- determining whether the component is within the acceptable manufacturing tolerance based on a predetermined pattern of the surface indicator that is visible in the component.
A casting system for manufacturing a component, comprising:
- a casting article having:
- a body;
- a diffusion exit surface connected to a first portion of said body and configured to extend above a nominal surface of said component;
- and
- at least one surface indicator feature extending from said diffusion exit surface and being configured to leave a mark in said component.
