Title:
内部連絡通路封鎖のサーモグラフィ検知
Document Type and Number:
Japanese Patent JP5480997
Kind Code:
B2
Abstract:
A method of thermal inspection of a component defining at least one internal passageway. The method includes receiving a continuous sequence of thermal images of at least an exit hole defined by the at least one internal passageway at a surface of the component. The method also includes delivering a pressurized airflow pulse into the at least one internal passageway, receiving a temperature response signal as function of time based on the received thermal images, determining a first derivative of the temperature response signal, and determining a level of blockage of the at least one internal passageway based on the first derivative of the temperature response signal.
