Phased Array Inspection Solution
Aircraft manufacturers, maintenance service providers, and airline operators have recently started using ultrasonic phased array technology to ensure the quality of their composite parts during manufacturing. Parts manufactured of carbon fiber reinforced polymer (CFRP) pose an inspection challenge because of their many shapes and thicknesses. The inspection of these corners is relatively new but is becoming more and more important with the increasing use of CFRP laminates in aircraft
structures.
Olympus offers a solution with its phased array instrument such as the OmniScan® PA to meet the most demanding requirements. This solution uses appropriate holders and curved linear arrays composed of 16 to 64 elements that fire in sequence to cover the entire corner in a single pass. The geometry of the probe allows for all of the ultrasonic beams to coincide at 90° with the surface of the part in a manner similar to flat-surface inspections. The main advantage of using the OmniScan PA for this
application is the possibility of inspecting the entire corner in one simple scan. With respect to the inspection speed, a typical setup can inspect along a corner up to 200 mm/s.

- Full coverage in a single scan
