FIELD: heating systems.
SUBSTANCE: invention refers to engine building, and namely to methods of detecting vibration combustion mode, mainly in low-toxic combustion chambers of gas turbine engines. In method of detecting vibration combustion in combustion chamber of gas turbine engine, during its operation, as dynamic parametre characterising availability of vibration combustion, there measured are constituent parts of vibrations of combustion chamber housing within the specified frequency range determined by building amplitude-frequency response of pressure fluctuations in combustion chamber during test of this type of engines.
EFFECT: invention allows detecting vibration combustion mode in combustion chamber of gas turbine engine during the whole operating period.
