Abstract
A method of determining a turbine inlet temperature for a gas turbine engine includes measuring pressure changes within a combustion section of the gas turbine engine during operation of the gas turbine engine to produce pressure versus time data, extracting a resonant frequency from the pressure versus time data, and calculating the turbine inlet temperature based solely on the resonant frequency.
