• Rotor blader

Failure of the middle bearing in an aircraft engine was reported. Tip-timing and RMS technique were carried out on a compressor rotor blade in the seventh stage above the middle bearing. The experimental analyses concerned both an aircraft engine with a middle bearing in good working order and an engine with a damaged middle bearing. A numerical analysis of the free vibration of the seventh stage blade was conducted to verify the experimental ones. Proposed in this paper is a method to prevent middle bearing failure.
