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： A system and method that allow inspection of hollow structures made of composite material, such as an integrally stiffened wing box of an aircraft. A wing box comprises top and bottom skins connected by a plurality of spaced spars. The system employs a plurality of scanners for inspecting different portions of each spar. The system uses dynamically controlled magnetic coupling to connect an external drive tractor to computer-controlled scanners that carry respective sensors, e.g., linear ultrasonic transducer arrays. A system operator can control the various components by means of a graphical user interface comprising multiple interaction regions that represent the individual scanner motion paths and are associated with respective motion script files.

摘要： Improved apparatus, systems, and methods for inspecting a structure are provided that use a probe having two ultrasonic transducer arrays. This enables simultaneous testing using two different test frequencies. The probe uses pulse echo ultrasonic signals at different frequencies to inspect the structure. The probe includes a support body having a fluid conduit formed therein. The fluid conduit provides flow paths for a couplant (such as water) that is used to couple the ultrasonic signals between the structure under test and the arrays. The fluid conduit is configured to quickly eject couplant and bubbles contained in the couplant.

摘要： Ultrasonic measurements of porosity in manufactured parts or materials are calibrated using reference standards in which parallel holes are drilled in the backside of a body of material. The holes simulate voids in a part which attenuate incident ultrasonic energy. The number, size and location of the holes determine the simulated level of porosity that may be used to calibrate an ultrasonic tester. Multiple reference standards representing different levels of porosity can be produced in the form of individual coupons, or in a single body having multiple groups of holes.

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： Improved apparatus, systems, and methods for inspecting a structure are provided that use a pedestal robot mounted on a rail system, a probe extension coupler, and an inspection probe capable of performing pulse echo ultrasonic inspection. A probe may also include sled appendages and an axial braking system to inspect over holes and off edges. A probe may also include an ultrasonic pulse echo transducer array for high rate inspection; the transducer array may be mounted in a bubbler shoe for individually coupling each of the transducers in the array. A rail system may also include an optical encoder for providing location information for the robot and axial braking system. A probe extension coupler presses the inspection probe against the structure for adjusting to changes in surface contours.
