介绍了由工作实践总结出的采用侧视双目镜测量CFM56系列发动机高压压气机(HPC)转子叶片损伤的接近方法——轴向接近法。该方法可有效提高HPC损伤测量的精度,避免由于孔探测量水平不足而导致的飞机不必要的停场时间和维修费用。
The method of approaching the axial damage of the CFM56 series engine high pressure compressor (HPC) rotor blades by side view binocular is summarized. The method can effectively improve the accuracy of the HPC damage measurement and avoid unnecessary stoppage time and maintenance cost of the aircraft due to the insufficient level of the hole detection level.
