METHOD FOR DETERMINING MALFUNCTION OF GAS TEMPERATURE SENSORS Russian patent published in 2024 - IPC G01M15/14 G05B13/04 

FIELD: gas turbine engine.

SUBSTANCE: automatic regulation and monitoring of the performance of a gas turbine engine (GTE), namely systems for technical diagnostics of the operating condition of the engine. The invention differs from the known ones in that, in addition, a signal about the current state of the engine from the complex engine controller is transmitted to the neural network controller of the set value of the gas temperature behind the turbine, where the set value of the gas temperature behind the turbine is generated and in parallel transmitted to the comparison circuit and the key switching circuit, the signal from the sensor is also transmitted in parallel to the comparison circuit and the key switching circuit; in the event of a sensor failure, the comparison circuit generates a signal to turn off the gas temperature sensor behind the turbine and transmits it to the key switching circuit, which switches the transmission of data transmitted to the complex engine regulator from the gas temperature sensor behind the turbine to data transmitted by a neural network controller of the set gas temperature value behind the turbine, which leads to compensation for sensor failure and ensures stable and reliable operation of the gas turbine engine control system.

EFFECT: increasing the efficiency of the method for controlling the gas temperature behind the turbine, which ensures more accurate execution of a given control program and makes it possible to reduce the specific fuel consumption for a flight in the event of a sensor failure, due to the generation of a specified signal about the gas temperature behind the turbine based on the one embedded in the neural network controller a given value of the gas temperature behind the turbine of a mathematical model of the working process in the engine (linear dependence or multi-level mathematical model using neural network algorithms).
