Abstract: An angle of attack sensor includes a housing, a heated chassis positioned at least partially within the housing and defining a pocket, a mounting plate positioned adjacent the heated chassis and having a circular opening, an external surface facing away from the housing, and an internal surface facing toward the housing, and a vane assembly extending through the circular opening of the mounting plate. The vane assembly includes a vane extending from a root to a tip and a vane base connected to the root of the vane and positioned within the pocket of the heated chassis such that the vane base is offset inwardly from the external surface toward the housing.

Abstract: A system for determining a health status of a positive temperature coefficient resistor (PTCR) heater assembly includes a PTCR heater assembly and a health monitoring system. An input voltage is provided to the PTCR heater assembly to provide heating. The health monitoring system includes a first sensor configured to sense the input voltage at the PTCR heater assembly and a second sensor configured to sense a current through the PTCR heater assembly. The health monitoring system is configured to determine a baseline characteristic and an observed characteristic each relating to an inrush peak of the PTCR heater assembly and based on the input voltage and the current. The health monitoring system compares the observed characteristic to the baseline characteristic to assess a health status of the PTCR heater assembly and outputs the health status for PTCR heater assembly diagnostics and/or prognostics.

Abstract: A methodology includes circulating a temperature-controlled and flow-rate-controlled medium through a container at a controlled flow rate and submerging a thermistor with the medium. With the thermistor submerged, a power output of the thermistor is determined and compared to a power criterion, after which classification of the thermistor occurs based on a comparison of the power output to the power criterion. The methodology can include submerging a reference thermistor within the medium and determining a reference power output of the reference thermistor with the reference thermistor submerged within the medium, the power criterion determined based on the reference power output.

Abstract: An apparatus and method for inspecting articles incorporating positive temperature coefficient resistors. The inspection apparatus includes a computing device, a power source, a housing, a support, and a thermal imager, each mounted within an interior volume of the housing. The inspection method includes receiving a first thermal image of the unpowered article mounted within the support and receiving a second thermal image of the powered article after an optimized time delay. The method further includes outputting a health indication of the positive temperature coefficient resistors based on a comparison of the first thermal image and the second thermal image.
