| 摘 要： | In a high thrust-weight-ratio aero-engine, turbine blades are exposed to extremely high temperature and pressure which sets higher demands in the blade cooling technology. To boost film-cooling effectiveness, an accurate,efficient, and all-sided inspection of film cooling holes is urgently requested to ensure the quality of turbine blades. The tiny size of film-cooling holes adds to extreme difficulties in the inspection process both by contact and non-contact measurement. This paper proposed a ...
