摘要： 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.

摘要： 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.

摘要： An angle of attack sensor includes a housing having an open first end and a closed second end, a heated chassis positioned within the open first end of the housing, a mounting plate positioned on the heated chassis adjacent the open first end of the housing such that an internal chamber is formed between the heated chassis and the mounting plate, a transducer compartment between the heated chassis and the closed second end of the housing, and a water management system located adjacent the internal chamber and the transducer compartment. The water management system includes an annular chamber positioned in the internal chamber, a first tube at a first end of the annular chamber, and a second tube at a second end of the annular chamber. The first tube has a hole such that the first tube is in fluid communication with the annular chamber and the internal chamber, and the second tube is in fluid communication with the annular chamber and the transducer compartment.

摘要： An air data probe includes a stationary housing assembly, an air data measurement unit, and a fluid sensing unit disposed proximate to an interface between the housing assembly and the air data measurement unit. The air data measurement unit is rotatable about a longitudinal axis of the air data probe, relative to the stationary housing assembly. The fluid sensing unit includes a second electrically conductive sensing surface physically and dielectrically spaced from a first sensing surface.

摘要： 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.
