摘要： A system method of estimating health of aircraft brake system friction material includes sensing a temperature of the friction material, and supplying the sensed temperature to a processor-implemented thermal model that is configured to estimate friction material temperatures at one or more locations on the friction material. The estimates of friction material temperatures are supplied to a processor-implemented thermal oxidation model that is configured, based on the estimates of friction material temperatures, to estimate friction material loss due to thermal oxidation. Data representative of runway fluid exposure are supplied to a processor-implemented catalytic oxidation model that is configured, based on the runway fluid exposure, to estimate friction material loss due to catalytic oxidation. The health of the friction material is estimated based on the estimates of friction material loss from the processor-implemented thermal oxidation model and the processor-implemented catalytic oxidation model.

摘要： Systems and methods for measuring the wear of carbon brakes of an aircraft are disclosed herein. The systems and methods include a 3-axis acceleration sensor module mounted on a brake assembly, the 3-axis acceleration sensor module configured to detect acceleration events of the brake assembly in three different component directions. The systems and methods further include a memory module operably connected to the 3-axis acceleration sensor module, the memory module configured to store acceleration events detected by the 3-axis acceleration sensor module and to store a pre-determined threshold for determining carbon brake wear based upon a number of acceleration events detected in a single component direction of the three different component directions. The systems and methods also include a processor module operably connected the processor module configured to compare the stored acceleration events detected in a single direction of the three different directions to the stored pre-determined threshold.

摘要： In one example, the disclosure is directed to a method of determining a length of a wear pin in a brake assembly. The method includes obtaining an input image of a portion of the brake assembly, such as with a camera. The input image includes the wear pin and a reference object, and the reference object has a known dimension. A processor may determine, based on the input image, an image dimension of the reference object. The processor may determine, based on the input image, an image dimension of the wear pin. The processor may further determine, based on the image dimension of the reference object, the image dimension of the wear pin, and the known dimension of the reference object, an estimated measurement of the dimension of the wear pin.

摘要： System and method are disclosed for data collection from landing gear components and providing predictive analytics. Methods comprise sending a signal to excite wheel assembly sensor located on a vehicle. In response to sending the signal excited the sensors, receiving a return signal encoded with measurement data. The measurement data is then stored on an RFID card, on an edge node and/or on a remote server. Upon receipt of the measurement data by the remote server, the remote server analyzes the data to generate predictive maintenance analytics data.

摘要： Energy scavenging health monitors are provided for assessing the health of components onboard aircraft and other vehicles, as are methods carried-out by energy scavenging health monitors. In various embodiments, the energy scavenging health monitor includes an energy scavenger system, a controller coupled to the energy scavenger system, and a first sensor coupled to the controller. During operation of the health monitor, the first sensor provides sensor signals to the controller, which are indicative of an operational parameter pertaining to a monitored device of the vehicle. Storage media contains computer-readable instructions, which when executed by the controller, cause the energy scavenging health monitor to determine when a predetermined trigger event has occurred based, at least in part, on electrical input signals received from the energy scavenger system. In response to occurrence of the predetermined trigger event, the controller further stores data indicative of the sensor signals in the storage media.

摘要： A power line communication based monitoring system includes an alternating current (AC) power distribution bus, a data source (such as a sensor circuit), a system modulator/demodulator (modem), and a data converter. The sensor circuit is configured to sense a mechanical state of a component and to supply a modulated sensor signal representative of the mechanical state to the AC power distribution bus. The system modem is in operable communication with the AC power distribution bus and is coupled to receive the modulated sensor signal therefrom. The system modem is configured, upon receipt of the modulated sensor signal, to demodulate the modulated sensor signal and supply a demodulated sensor signal. The data converter is coupled to receive the demodulated sensor signal from the system modem and is configured to convert the demodulated sensor signal to digital data in a standard digital data communications protocol.

摘要： In some examples, a system includes a memory configured to store a threshold level for collision prediction. The system also includes processing circuitry configured to determine that a collision likelihood at a potential collision location between the vehicle and an object is greater than or equal to the threshold level. The processing circuitry is also configured to cause one or more lights mounted on the vehicle to direct light towards the potential collision location or towards the object in response to determining that the collision likelihood for the vehicle is greater than or equal to the threshold level.
