DEVICE FOR DETERMINING MALFUNCTION OF GAS TEMPERATURE SENSORS Russian patent published in 2023 - 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 a neural network regulator of the set value of the gas temperature behind the turbine is additionally introduced, the dual output of which is connected to a comparison circuit and the second input of the key switching circuit, the input of which is connected to the output of the complex engine regulator, with a dual output of the gas temperature sensor behind the turbine also goes to the second input of the comparison circuit, the output of which is connected to the third input of the key switching circuit.

EFFECT: increasing the reliability of the gas temperature control system 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 neural network regulator of the set 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).
