  • Measurement of wall thicknesses particularly of a blade, by eddy currents
    Patent number: 7550968
    Abstract: A method for evaluating the wall thickness of a hollow part, of the turbomachine blade type, at least at a point having a determined radius of curvature at this point, within determined ranges of radii of curvature and thicknesses, including the determination of impedance values of an electrical circuit formed by an eddy current detector applied to the wall, and the insertion of these values into a digital processing unit with a neural network, wherein the network parameters have been defined in advance by learning on spacers having a determined radius of curvature and thickness in the ranges.

    Date of Patent: June 23, 2009
    Assignees: SNECMA, CNRS
    Inventors: Pierre-Yves Joubert, Yann Le Bihan, Olivier Lespinet, Aleksandra Mikic
  • MEASUREMENT OF WALL THICKNESSES, PARTICULARLY OF A BLADE, BY EDDY CURRENTS
    Publication number: 20080111543
    Abstract: The present invention relates to a method for evaluating the wall thickness of a hollow part, of the turbomachine blade type, at least at a point having a determined radius of curvature at this point, within determined ranges of radii of curvature and thicknesses, comprising the determination of impedance values of an electrical circuit formed by an eddy current detector (20) applied to the wall, and the insertion of these values into a digital processing unit with a neural network, wherein the network parameters have been defined in advance by learning on spacers having a determined radius of curvature and thickness in said ranges.
