Title: METHOD AND DEVICE FOR MEASURING THE DAMAGE OF A HOLLOW AEROPLANE COMPONENT OR HOLLOW GAS TURBINE COMPONENT
Abstract:
The present invention relates to a device for measuring the damage of a hollow aeroplane component or hollow gas turbine component (6) using a coordinate measurement arm (2), on which provision is made of a first sensor device (11) having an external contour sensor (7) for detecting the external contour of the component (6) and/or for determining the position of a damaged region and of a second sensor device (12) having an ultrasonic sensor (8) for detecting the contour of a cavity (16) in the component (6) and/or for ascertaining a wall strength of the damaged region and/or for ascertaining the wall strength after a repair of the damaged region, wherein a third sensor device (13) with a white-light interferometer (9) and/or a laser triangulation sensor is provided on the coordinate measurement arm (2).
