Narrowband Ultrasonic Spectroscopy for Nde of Layered Structures
NDE of airspace sandwich structures is often performed using a simple resonant transducer sensing the information in the frequency domain obtained due to the constructive and destructive interference of elastic waves. Application field of ultrasonic narrowband ultrasonic spectroscopy (NBUS) is likely to increase rapidly with the growing application of layered structures in modern aircraft, for ...
متن کاملGuided Wave Non-contact Ultrasonic for Nde
Non-contact ultrasonic, enables rapid testing of structures using ultrasonic tests that are not possible via conventional contact transducers. This paper reports on laser ultrasonic and air/gas coupled ultrasonic measurements that are performed remotely, do not require direct access to test area, do not need traditional ultrasonic coupling and do not have traditional C-scan fixture requirements...
متن کاملProgrammable Filter for Ultrasonic NDE Systems
Transversal filters based on the charge-coupled device (CCD) technology may be applied to processing received signals in an ultrasonic NDE system. Filters having a fixed response (fixed tap weightings) could be used to compensate for the characteristics of a given ultrasonic transducer. A more flexible arrangement allowing programmability employs a CCD delay line whose tap electrodes are access...
متن کاملUltrasonic Nde Techniques for Integrally Fabricated Rotors
Solid-state bonding methods, e.g., diffusion bonding and pressure welding, are becoming common manufacture and repair techniques for gas turbine engine components. Effective NDE inspection techniques are crucial to the utilization of this approach due to the high stresses on the bond plane associated with jet engine operation. Recently we have examined ultrasonic techniques for assessing bond q...
متن کاملNDE Applications of Air-Coupled Ultrasonic Transducers
Abslract In recent years, several new NDE applications of air-coupled, as opposed to liquid-coupled, ultrasonics have been seriously pursued. The applications range from throughtransmission testing of aerospace laminates and various honeycomb or foam filled materials, and solar cells, to pulseecho flaw detection in plastic electronic packaging materials and in-line inspection of large-diameter ...
