METHOD OF DETERMINING THE OPERATING MODES OF THE GAS TURBINE ENGINE, MEANING THE MINIMUM VALUES OF THE AXIAL POWER, ACTING ON THE RADIAL-STEERING BEARING Russian patent published in 2017 - IPC G01M15/14 

FIELD: engines and pumps.

SUBSTANCE: in the method of determining the operating conditions of a gas turbine engine corresponding to the minimum values of the axial force acting on the radial thrust bearing in which the signal from the sensor mounted on the bearing support is measured and the modes of operation of the engine are determined, the bearing and frequency of the bearing separator are determined, multiples of it by an integer number of times, not exceeding the number of rolling bodies, measure a dynamic signal, in the spectrum of which one observes the appearance of a component on one of the preliminary definitions frequency, determine the operating modes of the engine corresponding to the appearance of this component, and make them transient.

EFFECT: increasing the reliability of the bearing and the engine as a whole, reducing labor intensity and cost in the implementation of the method by maintaining the unchanged material part, expanding the scope of the method, including engine operation.
