Abstract
A method of imaging a turbine engine test component with a first surface and a second surface that is spaced from the first surface. The turbine engine test component includes a plurality of film holes with inlets formed in the second surface or interior that are fluidly coupled to outlets formed in the first surface or exterior. The method includes flowing airflow through the plurality of film holes of the turbine engine test component, obtaining thermographic data, determining a test dataset, and calculating a performance score.
Claims20
A method of performance scoring airflow with an inspection system through a turbine engine test component having a first surface and a second surface spaced from the first surface, and a plurality of film holes with inlets formed in the second surface fluidly coupled to outlets formed in the first surface, the inspection system including a pump assembly fluidly coupled to the turbine engine test component, a controller, a thermographic sensor, and an output device, the method comprising:
- flowing, using the pump assembly, airflow through the plurality of film holes of the turbine engine test component;
- obtaining, using the thermographic sensor during the flowing airflow through the plurality of film holes, thermographic data for at least a subset of film holes of the plurality of film holes;
- determining, using the controller, a temporal score based on the thermographic data;
- determining, using the controller, a test dataset comprising test airflow values for the subset of film holes, wherein the test airflow values are determined by at least the temporal score;
- calculating, using the controller, a difference between the test dataset and a reference dataset;
- calculating, using the controller, a performance score for the turbine engine test component based on at least the difference;
- and
- outputting, using the output device, the performance score to at least one of accept the turbine engine test component, reject the turbine engine test component, or adjust design of the turbine engine test component.
