    摘要： An ultrasonic probe includes a probe body having a contact surface and a cavity that is open at the contact surface, an ultrasonic transducer carried by the body, and a spacer within the cavity. The spacer has a first surface acoustically coupled to the transducer, and a second (coupling) surface within the cavity. The spacer propagates an acoustic signal between the transducer and the coupling surface. The coupling surface is spaced apart from the contact surface to form a recess within the body. The body further has at least one port for circulating a coupling fluid into the recess. Depth of the recess is selected to balance gravitational force on the coupling fluid versus surface tension of the coupling fluid so a bead of the fluid forms over an edge of a structure under inspection as the probe is moved over the edge.

    摘要： An ultrasonic probe for examining an item. The probe includes a body having a contact surface adapted for contacting the item when being examined and an ultrasonic transducer attached to the body and spaced from the contact surface. The probe further includes a spacer positioned in the body between the transducer and the contact surface for spacing the transducer from the item when being examined. The spacer includes a coupling surface facing the item when being examined and a transducer surface facing the transducer. The probe also includes a fluid outlet positioned adjacent the coupling surface of the spacer for delivering coupling fluid to the coupling surface as a film so that the coupling fluid tends to maintain contact with the spacer due to surface tension after the fluid is delivered through the outlet.

    摘要： An apparatus for the ultrasonic testing of internal areas of prefabricated composite assemblies as described. The composite assemblies have one or more internal areas formed therein. The apparatus includes at least one receive transducer, at least one transmit transducer, a vertical member, a support member slidably attached to the vertical member, a pair of substantially parallel hollow rods, and an ultrasonic testing system. Each rod comprises a transducer attachment end with receive transducers attached to the transducer attachment end of a first rod, and transmit transducers attached to the transducer attachment end of a second rod. The rods are slidably attached to the support member and manually movable with respect to a composite assembly to be tested. The ultrasonic testing system is coupled to the receive transducers through the first rod, and coupled to the transmit transducers through the second rod.

    摘要： System and method for enabling ultrasonic inspection of a variable and irregular shape. The system comprises one or more ultrasonic pulser/receivers, one or more ultrasonic transducer arrays, a shoe or jig to hold and position the array(s), data acquisition software to drive the array(s), and data analysis software to select a respective best return signal for each pixel to be displayed. This system starts with information about the general orientation of the array relative to the part and a general predicted part shape. More specific orientation of the transmitted ultrasound beams relative to the part surface is done electronically by phasing the elements in the array(s) to cover the expected (i.e., predicted) surface as well as the full range of part surface variability.
