Creeping Wave InSitu Inspection for the Rabbet of Aeroengine Blade

  • 摘要: 文章尝试利用爬波特性解决飞机叶片榫槽原位检测难题。分析了飞机叶片榫槽原位爬波检测的原理,介绍了仪器、探头的选用原则,设计了模拟叶片试块,确定了检测灵敏度,并对原位检测方法作了说明。通过对检测结果的分析表明,采用小尺寸高频双晶爬波探头可以有效地对发动机叶片榫槽裂纹进行原位检测,而且检测方便快捷,灵敏度高,信号容易辨别,从而为爬波检测技术开辟了新的应用领域。
    Abstract: Attempt was made with the characteristics of creeping wave, to solve the difficult problem that the rabbet crack of areoengine blade could not be inspected on the original position. The insitu creeping wave testing principle was analyzed, and the detector and probe selecting ways were introduced. In order to determine the testing sensitivity, a kind of simulative specimens was designed. At last, the insitu inspection method was explained. The experimental results showed that the technique was effective to find out the cracks in the rabbet of engine blade with small size, high frequency, doublecrystal creeping wave probe. It is convenient, fast, sensitive and easy to be distinguished. So a new application field was opened up for the creeping wave testing technique.
