Abstract
A temperature sensor assembly includes a body configured to receive a heated flow of air therein. The body, in turn, includes a leading surface in thermal communication with the heated flow of air, a first concave surface including a first plurality of vents, a second concave surface including a second plurality of vents, and an air injector disposed within the body. The air injector is configured to apply a suction pressure to the first plurality of vents and to the second plurality of vents.
Claims18
