Abstract

Damaged 1st stage compressor rotor blades of an aircraft were analyzed. Analysis revealed that the hit/dent mark on the leading edge of the blade No. 15 occurred as a result of damage due to impact of a soft, solid mass. The dark brown stains/deposits on the concave surface of the blade Nos. 15 and 16 appeared to be blood stains. There were no evidences of impact on the blades with hard objects such as metallic material and/or stones/pebbles. Evidences suggest possibility of bird-hit on the compressor blade No.15.
