    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： A method of inspecting a radius area of composite parts with an ultrasonic inspection system, the system includes at least one ultrasonic probe, an upper sliding surface, a lower sliding surface, an adjustable guide rail, and an adjustable encoder wheel rotatably coupled to a rotary encoder, is provided. The method includes generating a high frequency sound wave using the probe including a radius of curvature extending from a center point, the sound wave travels partially through the part, adjusting the guide rail to align the center point of the probe with a center axis of a part corner portion, sliding the part through the inspection system to inspect the corner portion using the sound wave by rotating the wheel and rotary encoder such that the arcuate distance of the part is recorded, adjusting the wheel to avoid any apertures defined within the part, and processing the sound wave information.

    摘要： A non-destructive inspection method, apparatus and system are provided for inspecting a workpiece having a curved surface with at least one predefined radius of curvature. The apparatus, such as an inspection probe, includes a plurality of transducer elements positioned in an arcuate configuration having a predefined radius of curvature and a curved delay line. The curved delay line has an outer arcuate surface having a predefined radius of curvature that matches the predefined radius of curvature of the transducer elements. The curved delay line also has an inner arcuate surface that has at least one predefined radius of curvature that matches the at least one predefined radius of curvature of the curved surface of the workpiece. In addition to the inspection probe, the system includes an excitative source for triggering the transducer elements to emit signals into the workpiece and a computing device to receive the return signals.

    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.
