摘要： Ultrasonic systems and methods for inspecting a channel member through a skin or panel are provided. The channel member may be a stiffener for an aircraft component such as a trapezoidal stringer attached to a skin of an aircraft fuselage. Transducers of the system are disposed on a side of the skin opposite the channel member. Ultrasonic waves generated on a first side of a skin propagate through the skin, across a channel member attached to a second side of the skin, and through the skin again to be received on the first side of the skin. Times of flight are measured for the collection of time-gated data. A two dimensional C-scan is generated for identifying flaws and irregularities in a structure by way of single-side ultrasonic non-destructive inspection (NDI).

摘要： A non-destructive method determines an amount of heat exposure to a resin-fiber composite substrate. A value of infrared energy reflected by a composite substrate is determined. The value of infrared energy reflected, or conversely absorbed, is correlated to a degree or amount of heat exposure. According to an aspect of the present invention, one method utilizes an infrared spectrometer to determine infrared absorbance of a composite substrate. The infrared energy of the reflected beam is then compared with the pre-determined value of infrared energy reflected off a reference heat damaged composite substrate to determine the amount of heat exposure.

摘要： An ultrasonic transducer device is pressed against the front surface of a structure, emits an ultrasonic pulse into the structure, and detects an echo profile from the structure. An indicator is activated if the echo profile includes a return pulse that at least is received from between the front surface and the back surface of the structure. An ultrasonic transducer device includes an ultrasonic transducer and a coupling element coupled to the transducer for disposition between the transducer and a surface of a structure. The coupling element serves as a delay line that allows time for quiescence in the transducer so that return pulses from shallow depths can be detected. The ultrasonic transducer is activated when multiple switches are pressed against a surface thus assuring both firm coupling and perpendicular disposition of the acoustic axis of the transducer relative to the surface.

摘要： Apparatus, systems, and methods for inspecting and monitoring bolted joints of metallic and composite structures for defects such as delamination and fatigue cracking are provided that incorporate ultrasonic transducers with load bearing washers. These active washers may be used for inspecting and monitoring a structure beneath such load bearing fasteners as bolts and nuts. Active washers may be used for continuous, periodic, and controlled inspections of bolted joints. Ultrasonic transducers may be permanently applied to a surface of a washer or recessed in a cavity on a surface of the washer. Inspection signals may be transmitted from ultrasonic transducers into a structure and reflected in pulse-echo application or received by another active washer on the opposing side of the structure in a through-transmission application.
