ABSTRACT:
A method and apparatus are provided for determining the amount and type of permanent deformation experienced by a turbomachine blade. According to the invention, small holes are drilled in at least three blades of the blade row. One hole is drilled in the inlet face of the blade shroud and another hole is drilled in the inlet face of the blade root. In addition, third and fourth holes are drilled in the exit face of the shroud and a sixth hole is drilled in the exit face of the root. Measurements are taken between the shroud holes on the middle blade and the root holes on the outer blades in the row on both the inlet and exit faces. The measurements are use to form triangles indicating the blade geometry. By comparing the changes in these triangles after substantial operating time, both the type and amount of permanent deformation can be determined.
