TOTAL AIR TEMPERATURE SENSING DEVICE

摘要

A total air temperature sensing device is disclosed. The device includes a conduit through which an air flow can be maintained; a cross member housed in the conduit and having a leading edge which is profiled so as to bring a portion of the air flow to rest at a stagnation region on the cross member; at least one temperature sensor disposed in or near to the stagnation region; and a sensor interrogation system for measuring the temperature sensed by the temperature sensor and interpreting the measured temperature in order to derive a total air temperature. A corresponding method of sensing total air temperature is also disclosed.
