Abstract

Findings of the analysis of a damaged first stage LP compressor rotor blade belonging to a SU-30 MKI aircraft are presented in this report. Examination showed that the compressor blade had suffered foreign object damage (FOD) on the leading edge. The impact of the foreign object was on the concave surface of the airfoil. Nature of the damages and the compositional analysis of the impacted region revealed that the object was metallic in nature and it contained elements such as ‘Cd’, ‘Fe’ and ‘Cr’. Based on the compositional analysis on the FOD region, it is stated that the foreign object was made of steel and plated with cadmium. The object was also painted in blue colour. Damage pattern suggests that the object probably had circular cross section.
