  • Total air temperature sensors
    Patent number: 10611499
    Abstract: A total air temperature sensor includes a probe head, a strut, and a turbulence inducing surface. The probe head has an airflow inlet and an airflow outlet. The strut defines a leading edge and an opposed trailing edge extending along a longitudinal axis, and connects between the probe head and an opposed probe mount. The turbulence inducing surface is defined in the strut aft the leading edge. The turbulence inducing surface is configured to trip a fluid boundary layer passing over the strut to transition from laminar to turbulent for moving flow separation toward the trailing edge to reduce acoustic noise emission from the total air temperature sensor.
    Type: Grant

  • AIRCRAFT TOTAL AIR TEMPERATURE ANOMALY DETECTION
    Publication number: 20160370236
    Abstract: An example method includes receiving, by a computing device, an indication of a measured total air temperature (TAT) from a temperature probe installed on an aircraft. The method further includes determining, by the computing device, a theoretical temperature corresponding to conditions at which the TAT is measured, and determining, by the computing device, a measured TAT anomaly condition based on the measured TAT and the theoretical temperature corresponding to the conditions at which the TAT is measured.
