Abstract
A method for improvement of T6 probes accuracy based on swirl angle includes predicting a swirl angle of a gas turbine engine based on a power of the gas turbine engine and a delta value. The method includes determining an error value of an exhaust temperature (T6) of the gas turbine engine based on the predicted swirl angle and a correlation function of swirl angle to error. Also, the method includes compensating a measured value of the T6 based on the error value.
