METHOD FOR DETERMINING TEMPERATURE AT TURBINE INLET FOR GAS TURBINE ENGINE USING ACOUSTICS (OPTIONS) AND GAS TURBINE ENGINE Russian patent published in 2023 - IPC G01K11/26 G01K13/02 G01K15/00

Abstract RU 2801254 C1

FIELD: gas turbine engine.

SUBSTANCE: method for determining a turbine inlet temperature for a gas turbine engine includes measuring pressure changes in the combustion section of the gas turbine engine during operation to obtain pressure versus time data, extracting a resonant frequency from the pressure versus time data, and calculating the turbine inlet temperature solely based on resonant frequency. In addition, a gas turbine engine and a method option are also provided.

EFFECT: enhancement of the production.
