METHOD FOR REGULATING FUEL SUPPLY TO GAS TURBINE ENGINE COMBUSTION CHAMBER Russian patent published in 2022 - IPC F02C9/26 

FIELD: gas turbine engines.

SUBSTANCE: invention relates to the field of controlling the operation of gas turbine engines (GTE), mainly aircraft and can be used to control the supply of fuel to a GTE with a multi-zone combustion chamber (CC). A method for regulating the fuel supply to the combustion chamber of a gas turbine engine, according to which the total fuel consumption into the engine combustion chamber is formed to maintain a given turbocharger rotor speed and the fuel consumption is controlled through two dispensers into groups of injectors depending on the engine operation mode. For the first dispenser, the maximum and nominal values ​​of the fuel consumption limitation are set. Additionally, the minimum value of the fuel consumption limit for the first dispenser is set; the fuel consumption through the first dispenser is formed as the difference between the total fuel consumption to the engine and the current fuel consumption through the second dispenser. The fuel consumption through the first dispenser is limited: from below - by the minimum value of the restriction, from above - by the maximum value of the restriction. The fuel consumption in the second dispenser is formed as the sum of two values, the first of which is determined by integrating the difference in fuel consumption through the first dispenser before its limitation and the nominal value of the fuel consumption limitation through the first dispenser, and the second is formed as the difference in fuel consumption through the first dispenser before and after its limitation.

EFFECT: increasing the accuracy of maintaining the rotor speed.
