Porosity inspection system for composite structures

摘要

A method and apparatus for inspecting a composite structure. A response sound signal to a sound signal sent into the composite structure at a location on the composite structure is detected. An attenuation is identified in the response sound signal detected in response to the sound signal sent into the composite structure at the location on the composite structure. An indication of whether additional evaluation of the location is needed based on a comparison of the attenuation in the response sound signal to a baseline attenuation value for porosity for the location on the composite structure is generated.

1. A method for inspecting a composite structure, the method comprising:
detecting a response sound signal to a sound signal sent into the composite structure at a location on the composite structure; identifying an attenuation in the response sound signal detected in response to the sound signal sent into the composite structure at the location on the composite structure; generating an indication of whether additional evaluation of the location is needed based on a comparison of the attenuation in the response sound signal to a baseline attenuation value for porosity for the location on the composite structure; generating a number of images of the composite structure; and associating a set of graphical indicators on the number of images in areas corresponding to a set of areas on the composite structure needing the additional evaluation using the number of indications to form a map of areas on the composite structure needing additional evaluation using the number of indications.
