Patent attributes
This invention relates to an engine synchronization method for aircraft equipped with at least two gas-turbine engines, where the respective speeds N1 of the low-pressure compressor spools of the gas-turbine engines are determined and a difference value N1 is calculated and subsequently on the basis of this difference value at least one trim value is calculated, on the basis of which, at least on one gas-turbine engine, a change of the setting is made, with subsequently the respective speeds N2 of the high-pressure compressor spools of the gas-turbine engines being determined and a difference value N2 being calculated and subsequently on the basis of this difference value, at least on one gas-turbine engine, the inlet temperature value T20, which is fed to the engine controller, being changed for synchronization.
