摘要：

A total air temperature sensor includes an airfoil body extending from an airfoil base to an opposed airfoil tip along a longitudinal axis. The airfoil body defines a leading edge and opposed trailing edge. The airfoil body defines an interior flow passage with an inlet for fluid communication of fluid into the interior flow passage and an outlet for exhausting fluid out from the interior flow passage, and wherein the airfoil body defines a bleed passage through the airfoil body between the leading edge and the interior flow passage. A temperature probe is mounted within the interior flow passage for measuring temperature of flow through the interior flow passage to determine total air temperature.

1. A total air temperature sensor comprising: an airfoil body extending from an airfoil base to an opposed airfoil tip along a longitudinal axis and defining a leading edge and opposed trailing edge, wherein the airfoil body defines a high pressure surface and an opposed low pressure surface each extending longitudinally from the airfoil base to the airfoil tip, wherein the airfoil body defines an interior flow passage with an inlet for fluid communication of fluid into the interior flow passage and an outlet for exhausting fluid out from the interior flow passage, and wherein the airfoil body defines a plurality of bleed passages through the airfoil body between the leading edge and the interior flow passage, wherein each bleed passage has an inlet in the high pressure surface and an outlet in the low pressure surface; and a temperature probe mounted within the interior flow passage for measuring temperature of flow through the interior flow passage to determine total air temperature.
