Abstract

The compressor rotor and stator blades pertaining to an aeroengine were examined to analyze the cause of failure. Investigation revealed that the 6th and 11th stage rotor blades were damaged due to FOD. The foreign objects were identified to be silica and/or alumino-silicate particles. The 10th stage stator blades were also damaged due to FOD as mentioned above. In addition, smearing of silver (Ag) was observed on the FOD regions of these blades. The source of Ag needs to be established.
