Acoustic emissions testing of air storage vessels at APTU is cost-savings effort
A new technique was recently used at the AEDC Aerodynamic and Propulsion Test Unit (APTU) at Arnold Air Force Base for inspecting the high pressure air storage vessels. An outside contractor was hired to perform high pressure acoustic emissions testing on the large bottles at APTU to detect flaws. Pictured is a contractor engineer performing calibrations on the sensors as they are being installed on the bottles. (U.S. Air Force photo/Rick Goodfriend)
