Cooling hole inspection system

An inspection system comprising:

• a thermographic sensor configured to capture thermographic data of a component having holes as a fluid is pulsed toward the holes;
• and
• one or more processors configured to temporally process the thermographic data to calculate temporal scores for the corresponding holes, spatially process the thermographic data to calculate spatial scores for the corresponding holes, and calculate composite scores associated with the holes based on the temporal scores and based on the spatial scores,
• wherein the composite scores represent a likelihood that the corresponding holes are open, blocked, or partially blocked.

A method for detecting blockage of cooling holes in a turbine blade, the method comprising:

• capturing thermographic data of the turbine blade and the cooling holes as a fluid is pulsed toward the cooling holes;
• temporally processing the thermographic data to calculate temporal scores for the corresponding cooling holes;
• spatially processing the thermographic data to calculate spatial scores for the corresponding cooling holes;
• and
• calculating composite scores associated with the cooling holes based on the temporal scores and based on the spatial scores,
• wherein the composite scores represent a likelihood that the corresponding cooling holes are open, blocked, or partially blocked.
