摘要： An example method for manufacturing a multicellular structure for acoustic damping is described that includes applying a porogen material to a solid support, inserting a multicellular frame into the solid support and through the porogen material so as to fill cells of the multicellular frame with the porogen material, fusing the porogen material, removing the multicellular frame from the solid support, and the multicellular frame contains a suspended fused porogen network attached to walls of the cells of the multicellular frame. The method also includes applying a solution to the suspended fused porogen network in the cells of the multicellular frame to percolate the suspended fused porogen network, curing the solution, and removing the suspended fused porogen network from the multicellular frame resulting in porous septum membranes of the cured solution in cells of the multicellular frame.

摘要： Systems and methods for indicating the health of brakes on an aircraft or a ground vehicle. One method for monitoring brake health calculates the ratio of input energy to output energy during braking. The input energy is a function of commanded brake force and speed. The output energy may be measured by measuring the increase in temperature or the actual brake force over time during brake application. When using brake temperatures, the temperatures in a pair of brakes may optionally be compared. If the respective measured temperatures of the two brakes differ by an amount that exceeds a specified threshold, the system produces an indication that one brake may require repair or replacement. Variability due to operational and environmental factors that affect measured temperature can be reduced by comparing the measured brake temperatures for one brake with selected brake temperature data collected from the same brake during other landings under similar conditions.

摘要： A sound-attenuating composite structure may comprise a honeycomb core assembly having a plurality of honeycomb cells defined by sidewalls, wherein the honeycomb core assembly is sandwiched between an inner impervious skin and a perforated outer skin. The sound-attenuating composite structure may further comprise a ceramic foam insert received in each of the honeycomb cells at a predetermined insertion depth to form an obstruction therein. Each of the ceramic foam inserts may have a predetermined thickness defined between substantially flat top and bottom surfaces. The sound-attenuating composite structure may have predetermined acoustic performance characteristic that are controlled, at least in part, by the predetermined thickness and the predetermined insertion depth.

摘要： Resistive inks and method of making resistive inks that utilize a phthalonitrile resin as a curable component in the inks are disclosed. In one example, a resistive ink is provided. The resistive ink comprises a solvent, a thermally-curable phthalonitrile-based resin dissolved in the solvent, and one or more conductive fillers. In some examples, the phthalonitrile resin can comprise a B-staged material.

摘要： A method, system, and computer program product for predicting abnormal operation of at least one component of a machine is provided. Real time monitoring data from an operating machine is received and monitoring features that are informative of likely abnormal operation are extracted and/or calculated. The monitoring features are applied to a prediction matrix that outputs probabilities of abnormal operation within one or more prediction time horizons. If the output probabilities exceed a threshold probability, then an alert can be output. Maintenance can be automatically scheduled in response to the alert.
