民航飞机主动红外热波成像检测技术应用进展

摘要

The basic nondestructive testing theory and the technological characteristics of the active infrared thermography are introduced by illustrating the different active heating methods such as impluse heating excitation, phase lockin heating excitation, ultrasonic excitation and microwave excitation.It is also presented the application of active infrared thermography in the fileds of aircraft structure destructive testing, aircraft skin corrosion testing, composite material destructive testing, cooling passage testing and crack testing of turbine blades.The existing application problems and developing trend of aircraft testing based on the active infrared thermography nondestructive testing are also presented.%根据主动加热方式不同,论述了脉冲加热、锁相调制加热、超声加热、微波加热等主动红外热成像无损检测技术理论基础和技术特点;综述了主动红外热成像无损检测技术用于飞机机体结构缺陷、蒙皮腐蚀、复合材料缺陷、发动机管路堵塞与叶片裂纹等无损检测方面的研究成果;结合主动红外热成像实验技术特点,指出了其在飞机检测方面存在的问题和发展方向.
