Abstract

A total air temperature probe includes an inlet through which airflow enters a primary airflow passage through the probe. A sensor flow passage is connected to the primary flow passage. Bleed ports extend between the primary airflow passage and a cross-port which extends laterally across the probe. An aspiration aperture in the cross-port couples the cross-port to an internal cavity of a strut of the probe. The aspiration aperture can be centered within the cross-port to provide symmetrical deicing heater error behavior of the probe during changes in angle of attack. An aspiration tube couples the internal cavity of the probe to a pressure source.
