Research and Design of Differential Gas Temperature Measurement System for Gas-Turbine Engines

Abstract

The article deals with the creation of a differential system for measuring the temperature of GTE gases using jet-acoustic sensors, which makes it possible to improve performance. A short review was conducted and technical solutions were proposed to eliminate the disadvantages of existing high-temperature measurement equipment. The ways of solving problems related with the allocation of an informative parameter from a nonlinear polyharmonic signal, its transformation and functional processing are suggested. The results of experimental studies confirming the operability of the proposed measurement system are presented.
