Dynamic vibration analysis of ti-alloy gas turbine blade rotating at high speed after grind-out repair of foreign object damage

Vibration analysis of gas turbine blade contributes to progress in Aerospace and Aeronautics industries. Most commonly, identification and suppression of unwanted vibration is essential need. Modes of vibrations and natural frequencies are influenced by damages caused by foreign object impact. These are more pronounced for variant crack geometry near to the root of blade. Statistical report and its post repair performance capability are inadequate in literature. It gives information on subject of dynamic nature of mend turbine blades at working condition. Threshold damage geometry and choice of locations can be defined for the meticulous turbine blade helps in regular maintenance. © IAEME Publication
