摘要
航空发动机叶片作为发动机的重要零件,在恶劣的工作环境下容易产生裂纹等缺陷,但其具有复杂的曲面结构,传统的无损检测技术存在一定的局限性。采用超声红外热像技术对叶片裂纹进行检测,开展了超声红外热像技术原理及系列试验研究,并搭建了超声红外热像检测试验平台,实现了对航空发动机导向叶片和工作叶片细微裂纹的检测,展示了该技术对航空发动机叶片裂纹的检测能力。
Aeroengine blade is the most important part of the engine.Severe working environment makes it easy to crack.Aeroengine blades have complicated surface structures that make it hard for traditional NDT technology to inspect.The ultrasonic infrared thermographic technology was used to detect the cracks.A series of research on ultrasonic infrared thermography technology was carried out.This paper discussed the principle of ultrasonic infrared thermography technology and the inspection system setup.The detection of fine cracks in guide blades and working blades of aeroengine is realized,and the ability of detecting cracks in aeroengine blades is demonstrated.
