Abstract

One 1st stage compressor blade and two turbine blades with suspected FOD were sent to the laboratory for analyzing the nature of damage and the composition of the foreign object, if any, which might have led to FOD. Suitable samples were taken from the blades and subjected to EDX analysis in SEM. The damages appeared as if they have been caused by solid object(s). However, no remnant of the object was found left on the blades from which the composition of the suspected foreign object could be determined. The shiny metallic deposit seen on the turbine blades was analysed to be smeared aluminium.
