Feasibility Study of Fluidic Turbine Temperature Sensors in Gas Turbine Engines
Keyword(s):
This paper is intended to introduce the reader to the subject of turbine temperature controls, and to present the results of a preliminary engine evaluation of two miniature fluidic oscillator temperature sensors. These units were installed in the air-cooled vanes of the first turbine nozzle on a Lycoming T55 L7 Engine and have successfully measured the gas temperature at the turbine inlet station for more than 8 hr. In addition to the test results, topics relating to the subject of turbine temperature controls, such as signal error compensation and temperature averaging, will be briefly discussed.
