First Claim
Patent Images
1. A method of thermal inspection of a part having at least one internal cavity, the method comprising:
- flowing a fluid through the at least one internal cavity;
measuring a temperature at one or more locations on the part over time;
calculating at least one of a first and a second derivative of the temperature with respect to time; and
comparing at least one of the first or the second derivative to one or more baseline values to determine if the part meets a desired specification.

Abstract
A method of thermal inspection of a part having at least one internal cavity is provided. The method includes flowing a fluid through the at least one internal cavity. The method also includes measuring a temperature at one or more locations on the part over time. The method further includes calculating at least one of a first and a second derivative of the temperature with respect to time. The method also includes comparing at least one of the first or the second derivative to one or more baseline values to determine if the part meets a desired specification.

10. A system for thermal inspection of a part having at least one internal cavity, the system comprising:
-
a fluid source configured to provide a flow of a fluid to the part, a camera configured to capture a plurality of images corresponding to a thermal response of the part to the flow, and a processor configured to; calculate at least one of a first and second derivative of a temperature with respect to time; and compare at least one of the first or the second derivative to one or more baseline values or an acceptable range of values to determine if the part meets a desired specification. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
