Abstract

A total air temperature probe comprising: a housing having an inner surface defining an airflow passage; a first section of the airflow passage of the housing comprising a first section having a first cross-sectional area an airflow inlet funnel and an inertial separation bend downstream of the airflow inlet funnel, wherein the airflow passage is configured to be substantially straight; and a second section of the airflow passage of the housing, the A second section includes a main exit channel and an elongated outlet having a second cross-sectional area, wherein the gas flow passage is contoured to direct particle deflection to the elongated outlet, wherein the second section is at the first downstream of a section, and wherein the first cross-sectional area is greater than the second cross-sectional area.

Description

Background technique [0001] Safe and efficient aircraft operation requires accurate temperature measurement. A total air temperature (TAT) probe, usually located on the outside of the fuselage or at the engine intake, measures the maximum air temperature obtained by converting the kinetic energy of the surrounding airflow into heat energy. The TAT probe stagnates the surrounding free-stream airflow to measure the static air temperature and the resulting adiabatic temperature rise. Aircraft operators use this measurement and the values ​​derived therefrom for, among other things, actual airspeed calculations and fuel burn monitoring. [0002] Icing conditions can be a problem for the accuracy of TAT measurements. During in-flight icing conditions, solid particles, ice crystals, ice particles, and / or water droplets may accumulate on the sensing element within the probe, causing erroneous measurements. Conventional TAT probe designs use streamlined airflow paths and inertial s...
