Advanced Structural Instrumentation. Volume 2
Abstract
This report presents the results of the development and test of a variety of steady-state strain and temperature sensors specifically aimed at application in hot sections of advanced gas turbines. In each case, the sensors have shown success in the laboratory, and tests and results described herein were designed to simulate the actual turbine environment. Most of the testing was carried out in the UTRC vacuum spin rig which was able to achieve speeds and temperatures characteristic of advanced gas turbines. Volume I is an overview of the sensors, physical description, summary comparison of results and conclusions and recommendations. Volume II gives the details of the sensor fabrication and installation as well as evaluation of the data acquired. The report is divided into the section each of which gives the details of a specific sensor tested in this program. Temperature sensors tested in the present program include conventional wire thermocouples and an advanced type of thin film thermocouple deposited directly on the test piece. The temperature measuring capability of twin core optical fiber sensor technology has also been demonstrated. Remote sensing of temperature was achieved with a thermographic phosphor technique, and optical pyrometry was used as a control throughout the program. Additionally, the feasibility of advanced concept heat flux sensors on a turbine blade was demonstrated. (rh)
