Title: Method for testing the condition of a shaft of a rotary machine

Filed: 2006-05-31
Abstract: A method for non-destructive testing of a drive shaft that is accessible by only one of its ends in longitudinal waves, using a multi-element annular ultrasonic transducer. Such a transducer consists of independent elements that can be excited by electrical pulses of the same frequency, but for which different electronic phase shifts will be applied, in the invention, to the pulses transmitted to the elements. Such an electronic phase shift allows the focussing or deflection of a final beam synthesized by all the elements constituting the transducer, the said final beam being concentrated to adopt a generally cylindrical shape with a cross-section that is far smaller than the cross-section of the shaft to be tested and is highly energetic over a long distance due to the waveguide effect created by the cylindrical geometry of the shaft.
