Patent attributes
An abrasive stream perforation (ASP) system and method for forming a plurality of perforations through a composite part. The ASP system may include a compressed air source, a particulate source, a valve, nozzles, and a positioning device. The valve is actuatable between an open state and a closed state. The compressed air and particulate are simultaneously forced through the valve in its open state and then forced through the nozzles and against the surface of the composite part, forming the perforations through the composite part. The support frame maintains the nozzles in a spaced relationship to each other and a selected distance away from the composite part. The positioning device is fixed to the support frame and actuates the support frame relative to the surface of the composite part for proper positioning of the nozzles and the resulting perforations.
