Abstract
A method for checking a blade contour of a turbomachine, in particular a gas turbine, wherein an actual contour (1; 1′) of a blade is detected, wherein a target contour of the blade is scaled and the actual contour is compared with said scaled contour (2).
Claims15
A method for checking a blade contour of a turbomachine, comprising:
- registering an actual contour of a blade;
- scaling a setpoint contour of the blade, the scaling being a shape-invariant or geometrically similar change of the setpoint contour by enlargement or reduction of the setpoint contour as a whole, the setpoint contour being scaled so that a distance to the actual contour becomes minimal;
- and
- comparing the actual contour to the scaled setpoint contour, in order to determine if the actual contour is within a predetermined tolerance band around the scaled setpoint contour.
