In-process vision detection of flaw and FOD characteristics

摘要

An inspection system ( 9 ) includes an idler wheel ( 61 ) that is coupled to a fabrication system ( 8 ) and is in contact with a backing layer ( 65 ) of an applied material ( 64 ). A rotation sensor ( 63 ) monitors the idler wheel ( 61 ) and generates a rotational signal. A controller ( 24 ) is coupled to the rotation sensor ( 63 ) and determines a characteristic of one or more flaws and FOD ( 19 ) on a composite structure ( 12 ) in response to the rotation signal.
