METHOD FOR REGULATING AN AIRCRAFT TURBOJET ENGINE Russian patent published in 2022 - IPC F02C9/28 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to the field of aircraft engine construction, namely, to methods for regulating aircraft turbojet engines. The method for regulating an aircraft turbojet engine includes determining the operating frequency range of rotors with a high level of vibration of the housings. To regulate an engine equipped with a rotary guide device of a high-pressure compressor, previously on several engines based on a previously defined range of rotation frequencies of a high-pressure rotor and a low-pressure rotor, the angle of installation of the rotary guide device of a high-pressure compressor is changed and the dependence of the vibration level of the engine housings on the value of the ratio of rotation frequencies of high and low-pressure rotors, determined by the mentioned angle. The value of the ratio of the rotation frequencies of the high and low-pressure rotors is selected, at which the required permissible value of the vibration level of the housings is provided. Based on the data obtained, when debugging the engine, the installation angle of the input guide device of the high-pressure compressor is adjusted.

EFFECT: reducing the vibrations of the engine housings equipped with a rotary guide device of a high-pressure compressor over the entire operating range, which leads to increased reliability of the engine and increased flight safety.
