Patent number: 10197474Abstract: A system for use in inspecting a component having flow openings defined therein. The system includes a fluid injector in flow communication with the component, wherein the fluid injector provides fluid to the component such that the fluid is discharged from the flow openings. A sensing sheet is coupled to or positioned proximate to the component such that the fluid discharged from the flow openings is received at the sensing sheet, wherein the sensing sheet is formed from pressure-sensitive material. A light source emits light towards the sensing sheet such that the pressure-sensitive material is excited to an energy level. The system further includes an imaging device that captures images of a change in color of the pressure-sensitive material as a function of a pressure of the fluid received at the sensing sheet, wherein the change in color represents a pressure distribution across the sensing sheet based on a flow profile of the fluid discharged from the flow openings.Type: GrantFiled: May 4, 2017Date of Patent: February 5, 2019Assignee: General Electric CompanyInventors: Anquan Wang, Guanghua Wang, James Peter DeLancey
