Due to recent technological advances in ultrasonic flaw detecting apparatus (broad band characteristic), it is shown that ultrasonic pulse-echo inspection of aircraft tires is now possible. The critical acoustic properties of rubber and rubber composites have been studied so that optimum system requirements may be determined. Using off-the-shelf inspection components, a prototype inspection system has been constructed to demonstrate the ability of pulse-echo, ultrasonic inspection of tires to locate critical internal flaws and structural elements. Areas of electronic and to locate mechanical refinement necessary to complete semi-automated and fully automated inspection systems are presented. Importance and applications of defect standards for aircraft tires it also considered in connection with inspection evaluation. (Author)
