Abstract

An air data probe includes a probe head defining a longitudinal axis between a forward tip and aft base. The probe includes a thermocouple having a sense end in the forward tip to measure the temperature in the forward tip. The probe includes a port opening defined in a side of the probe head and opening at an angle with respect to the longitudinal axis. The probe includes a bulkhead within the probe head. The bulkhead has a chamber in fluid communication with the port opening. The chamber includes a single chamber inlet having an elongated cross-sectional shape. The single elongated chamber inlet is in fluid communication with two downstream pressure conduits to provide redundancy in case one of the two pressure conduits is blocked.
