METHOD FOR CONTROL OF FUEL SUPPLY TO COMBUSTION CHAMBER OF GAS TURBINE ENGINE, FUEL SUPPLY SYSTEM AND GAS TURBINE ENGINE Russian patent published in 2022 - IPC F02C7/228 F02C9/34 

FIELD: engine building.

SUBSTANCE: group of inventions relates to a method for the control of fuel supply to a combustion chamber of a gas turbine engine, a fuel supply circuit and a gas turbine engine. The method for the control of fuel injection of a gas turbine engine is carried out using fuel supply circuit (100). In this case, fuel supply circuit (100) contains pre-injection line (141) and main injection line (142). During the supply distribution transition between pre-injection line (141) and main injection line (142), the method includes following stages: a) determination of at least the minimum value to be maintained relatively to the pressure value; b) determination of at least one hydraulic value of the fuel supply circuit; c) based on the determined hydraulic value in the fuel supply circuit, the calculated value of the fuel supply distribution corresponding to the minimum value to be maintained is calculated; and the fuel supply distribution is switched to the calculated value of the fuel supply distribution.

EFFECT: obtaining a method for the control of fuel supply to a combustion chamber of a gas turbine engine.
