    摘要： An ultrasonic inspection apparatus operable within a channel associated with a structure is described. The apparatus includes at least one transducer and a holder. The holder includes a material having a flexibility and tensile strength such that a spring force is provided for maintaining a position of said holder within the channel of the structure. The holder includes a plurality of transducer indexing nodes therein for mounting of the transducers, and each node provides a single point of contact between the holder and the transducer. The transducer indexing nodes are fabricated having a material flexibility and tensile strength with respect to a remainder of the holder for positioning of the transducers along surface variances that define the channel.

    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： 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.

    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.
