由美国声学公司、Wright研究与发展公司以及麦道公司合作研制的声发射装置,从1989年2月起已经用于F—15战斗机的全尺寸疲劳检测试验。试验包括该飞机的几个大型部件,特别是关键受力部件,如机翼与机身的接头安装边等。为了获得全面可靠的数据,实际试验将历时两年总计约3200h。 Acoustic emission devices developed by the American Acoustics Company, Wright Research and Development Corporation and the McDonnell Douglas Company have been used for full-scale fatigue testing of F-15 fighters since February 1989. The test consisted of several large components of the aircraft, particularly key stressed components such as the wings and fuselage joints. In order to obtain comprehensive and reliable data, the actual test will lasted two years totaling about 3200h.
