Total air temperature probe with concave flow path transitions to outlet

A total air temperature probe comprising:

• a housing including:
• an inlet scoop;
• an outlet;
• a main airflow passage extending from the inlet scoop to the outlet, the main airflow passage including:
• 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;
• a lower outlet surface opposite the upper outlet surface and extending from a split point in the housing to the outlet;
• a first side surface extending from the inlet scoop to the outlet, the first side surface including:
• a first planar portion extending from the inlet scoop;
• and
• a first concave portion extending from the first planar portion to the outlet;
• and
• a second side surface opposite the first side surface and extending from the inlet scoop to the outlet, the second side surface including:
• a second planar portion extending from the inlet scoop;
• and
• a second concave portion extending from the second planar portion to the outlet;
• wherein the upper outlet surface is consistently concave toward the outlet;
• an exit that extends through the housing;
• and
• a total air temperature sensor flow passage that branches off from the main airflow passage at a location between the lower inlet surface and the lower outlet surface and that extends to the exit;
• and
• a sensor assembly positioned in the total air temperature sensor flow passage.
