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 measurement device and method in which an ultrasonic transducer is acoustically coupled to an object to be measured by a resilient material contact layer. The transducer transmits a plurality of consecutive ultrasonic transmit signals into the object being measured, the transmit frequency of each of the plurality of transmit signals being distinct from the frequency of the other transmit signals of the plurality of transmit signals. Signal echoes of the transmitted signals are received, and based on the received signal echoes, at least one transmit frequency to be used for ultrasonic measurement of the object is selected.

摘要： An apparatus for ultrasonic inspection of an object. A tire is mounted for rolling along the surface of the object. It contains a liquid and a transducer assembly. The transducer assembly is positioned in the tire adjacent a portion of the surface of the tire in contact with the object. The liquid and the surface of the tire in contact with the object provide an acoustic bridge between the transducer assembly and the object. An electric signal processing system is connected to the transducer assembly. It generates electric signals which are converted to acoustic signals in the transducer assembly to place acoustic signals in the object. Acoustic signals returned from the object are converted to electric signals by the transducer assembly, and are processed in the electric signal processing system to indicate flaws in the object.

摘要： Methods and systems are provided for protecting an acoustic liner having a perforated facesheet from water leakage during a through-transmission ultrasonic (TTU) inspection using an ultrasonic squirter system. The testing method utilizes a repositionable mask that covers the openings in the perforated facesheet. The repositionable mask is comprised of a pressure sensitive adhesive that adheres to the surface of the perforated facesheet. The repositionable mask can be removed after completing a TTU inspection and can be reused for subsequent TTU tests with minimal adverse effects on the mask or on the facesheet. For ease in handling, the repositionable mask may be configured with a semi-rigid backing carrier.

摘要： A lightweight apparatus for performing ultrasonic immersion inspection of a workpiece in an arbitrary orientation that uses significantly less couplant and has a reduced footprint size while providing ultrasonic performance levels comparable to those typically reached using immersion tanks, bubblers, or Dripless Bubblers™ while accommodating large and small ultrasonic beamwidths. The apparatus can be used with manual, automated, or electronic scanning techniques. The apparatus provides a quickly enabled ultrasonic coupling means that minimizes the area of the part wetted, and also can recover spent couplant. As a result, this reduces the number and type of contaminates to which the workpiece is exposed when used when compared to prior art immersion tanks and bubblers.

摘要： A method and apparatus are disclosed for coupling ultrasound between an ultrasonic transducer and an object. A scanning element is attached to an ultrasonic transducer to form an integral transducer assembly in which an ultrasound emitting surface of the ultrasonic transducer is positioned in a fluid cavity of an upper chamber. The ultrasonic transducer assembly may be moved relative to the object to be scanned in order to adjust the focus of the ultrasound. Adjusting a lower wall of the upper chamber in close proximity to the object to be scanned forms a thin film of coupling fluid between a planar region of the lower wall and the upper surface of the object.
