Turbine Inlet Gas Temperature Sensor for Engine Control.

摘要

The report describes a research and development program the object of which is the design,analysis,testing and demonstration of a nuclear radiation sensor system to measure the turbine inlet gas temperature (TIGT). This sensor is constructed on the basis of the electron radiation beam,transmitted across the turbine flow duct,being attenuated proportionally to the gas density. A concurrently obtained pressure signal feeding into an electronic computing system generates,from the basic laws of electron beam attenuation and the gas law, a signal proportional to the mean gas temperature across the turbine flow duct. The sensor as a whole has been named the gas-temperature-density (GTD) sensor. (Author)
