摘要： A sensor includes a mount arranged along a sensor axis, an airfoil body fixed to the mount and having a first face and second face extending along the sensor axis, a heater element, and a temperature probe. The heater element and the temperature probe are positioned within the airfoil body and extend axially along the airfoil body. The airfoil body defines within its interior a pressure channel having an inlet segment extending between the heater element and the first face of the airfoil body to prevent ice formation and/or melt ice entrained within air traversing the pressure channel. Gas turbine engines, methods of removing ice or preventing ice formation, and methods of making sensors are also described.

摘要： A total air temperature probe includes a housing including an inlet scoop, an outlet, a main airflow passage extending from the inlet scoop to the outlet, an exit that extends through the housing, and a total air temperature sensor flow passage and a sensor assembly positioned in the total air temperature sensor flow passage. The main airflow passage includes an upper inlet surface extending from the inlet scoop, a lower inlet surface opposite the upper inlet surface and extending from the inlet scoop, an upper outlet surface extending from the upper inlet surface to the outlet, and a lower outlet surface opposite the upper outlet surface and extending from a split point in the housing to the outlet. The total air temperature sensor flow passage branches off from the main airflow passage and extends to the exit. The upper outlet surface is consistently concave toward the outlet.

摘要： A sensor includes an airfoil body, a heater element, and a temperature probe. The airfoil body defines a sensor axis, an insulating cavity, and extends between a leading edge and a trailing edge of the airfoil body. The heater element extends axially within the airfoil body and is positioned between the leading edge and the trailing edge of the airfoil body. The temperature probe extends axially within the airfoil body, is positioned between the heater element and the trailing edge of the airfoil body, and is separated from the heater element by the insulating cavity to limit thermal communication between the temperature probe and the heater element. Gas turbine engines, methods of making sensors, and methods of thermally separating temperature probes and heater elements in sensors are also described.

摘要： A sensor includes an airfoil body, a heater element, and a temperature probe. The airfoil body defines a sensor axis and having a leading edge, a trailing edge, and an ice accretion feature. The heater element extends axially through the airfoil body between the leading edge and the trailing edge of the airfoil body. The temperature probe extends axially through the airfoil body between the heater element and the trailing edge of the airfoil body. The heater element is axially overlapped by the ice accretion feature to accrete ice chordwise forward of a tip surface aperture. Gas turbine engines, methods of making sensors, and methods of accreting ice on sensors are also described.

摘要： Deicing performance of a total air temperature (TAT) probe may be improved by reducing the size of a frontal projected area upstream of an inertial bend of the TAT probe. In accordance with various embodiments, a TAT probe may comprise an airflow inlet having a first surface substantially parallel to an incoming airflow, a primary airflow passage through the TAT probe from the airflow inlet to a primary airflow outlet, and a total air temperature sensor assembly disposed within a sensor flow passage. In various embodiments, the sensor flow passage may be oriented perpendicular to a mounting surface of the TAT probe. Further, the first surface may be perpendicular to the sensor flow passage. In various embodiments, the airflow inlet may have a second surface that is inclined relative to the first surface to help facilitate a desirable pressure gradient and boundary bleed passage function.
