Technical Article---Peer-Reviewed


Failure of low-pressure turbine nozzle guide vane (NGV) in an aero gas turbine engine is analyzed using computational approach. Breakage in the cooling system of the nozzle guide vane reducing the cooling effectiveness is found to be the main cause of NGV failure. Microstructure analysis also shows severe oxidation due to high temperature experienced in service leading to erosion of the NGV.
