摘要： A method for diagnosing the health of a transducer may include transmitting a signal to a transducer to cause the transducer to transmit a stress wave into an object being monitored, wherein the signal has a predetermined frequency range or bandwidth. The method may also include receiving response data for the transducer and transforming the response data to data representative of an impedance curve of impedance versus frequency for the predetermined frequency range. The method may further include extracting selected parameters from the impedance curve to diagnose the health of the transducer.

摘要： Vibration-damping blankets are attached to the back surfaces of fairing panels of a flight vehicle (e.g., an aircraft or spacecraft) to reduce vibration, fatigue, structure and airborne transmitted energy, and cabin noise. In one case, the flight vehicle fairing has an exterior comprising exterior surfaces of a multiplicity of removable panels. A method of retrofitting the flight vehicle with vibration-damping blankets comprises: removing a panel from the flight vehicle exterior; attaching a vibration-damping blanket to a back surface of the removed panel; and installing the panel with attached vibration-damping blanket on the flight vehicle with the exterior surface of the panel forming part of the flight vehicle exterior. In one embodiment, the vibration-damping blanket comprises polymeric (e.g., aromatic polyamide) fibers in a nonwoven structure.

摘要： A sensor device for monitoring and testing for potential corrosion of structural elements is disclosed comprising a soluble material disposed adjacent to at least one conductor in a transmission line that reacts to the presence of moisture causing a detectable change in an electrical property of the conductor. The conductor may comprise a conductive ink that is disrupted when the soluble material dissolves beneath it. Alternately, the nonconductive soluble membrane may separate two conductors and moisture causes a disruption in the soluble membrane allowing the two conductors to short. Detected changes in the electrical properties of the one or more conductors can be used to indicate potential corrosion or structural imparement in the structural element. Connection to the sensor device may be through a connector or using a wireless reader which remotely energizes the sensor device comprising one or more RFID chips.

摘要： A structural health management device, system and method are provided for facilitating the inspection of a structure, such as in accordance with a condition-based maintenance strategy. A structural health management device may include a radio frequency identification (RFID) tag and at least one sense line communicably coupled to the RFID tag and configured to extend at least partially along a workpiece. The sense line may be formed of different materials depending upon the objective of the inspection. The RFID tag may include processing circuitry and an antenna configured to facilitate offboard communication. The processing circuitry may be configured to interrogate the at least one sense line to determine a change in continuity which is indicative of a change in the structural health of the workpiece. The structural health management device may therefore detect the onset of structural issues in a timely manner.
