Research Analysis of Advanced Sensors for Turbine Inlet Gas Temperature.
Abstract
The final report describes results of a program to perform a comprehensive research analysis of the various advanced methods of sensing and providing an electrical signal for controlling the Turbine Inlet Gas Temperature (TIGT) of advanced gas turbine engines and recommends three methods which appear most promising for further development. Phase I completed the literature search, concept definition and selection, engine interface constraints definition, and performance objectives of the system. A review of the operating objectives of the sensor (800 to 3000F, plus or minus 10F accuracy and a response time of 10 msec) indicates that the greatest consideration should be given to response. Advanced engines that employ compressor bleed for blade cooling will require extremely high response TIGT sensors to prevent over-temperature failure after inadvertent rapid engine surge. A total of twelve different concepts were selected for detailed engineering analysis. In Phase II each concept was analyzed for response, accuracy, reliability and other important factors that would determine its relative potential in solving the TIGT measurement problem. (Author)
