Abstract:
In a gas turbine engine of the type which includes an inlet particle separator, there is provided apparatus for measuring the temperature of the air entering the engine compressor.
A remote temperature probe is disposed in a feed duct having an inlet in flow communication with the engine inlet upstream of the particle separator and an outlet disposed intermediate the particle separator and inlet to the engine compressor. Airflow through the feed duct is generated by the pressure drop across the particle separator without the use of compressor bleed or other air sources which result in performance degradation of the engine. Temperature measurement errors during engine anti-icing are reduced by selectively cross-bleeding a predetermined quantity of anti-icing air into the feed duct during activation of the engine's anti-icing system. The response rate of the probe is significantly improved by enclosing the probe in an impingement heat transfer blanket.
