  • Determining the extent of a lateral shadow zone in an ultrasound inspection method
    Patent number: 7415865
    Abstract: A method of determining the extent of a lateral shadow zone corresponding to an edge of a part in a method of inspecting the part in immersion by means of an ultrasound beam, the method consisting in determining the extent of the shadow zone from the edge of the part by measuring the effective section of the ultrasound beam at the surface of the part, and in determining said effective section from variations in the amplitude of an echo of the beam as a function of the distance between the axis of the beam and the edge of the part.
    Type: Grant
    Filed: December 23, 2005
    Date of Patent: August 26, 2008
    Assignee: Snecma
    Inventors: Jean-Yves Chatellier, Richard Coulette
  • Installation for non-destructive inspection of a part
    Patent number: 7305898
    Abstract: An installation for non-destructive inspection makes use simultaneously of sensors responsive to different physical characteristics. In an example, a sensor support, e.g. a kind of carriage having running wheels via which it comes into contact with the surface to be inspected, is fitted with two types of sensor, namely an eddy current sensor and at least one ultrasound sensor.

  • Method of using ultrasound to inspect a part in immersion
    Publication number: 20060162457
    Abstract: A method of using ultrasound to inspect a part in immersion, by means of a focused beam of ultrasound waves oriented perpendicularly to the surface of the part, the method consisting, when the axis of the focused beam is close to an edge of the part, in tilting the axis towards said edge relative to the normal to the surface of the part in order to eliminate the lateral shadow zone over all or substantially all of the depth of the part.
