GAS TURBINE ENGINE REGULATION SYSTEM Russian patent published in 2021 - IPC F02C7/22 F02C7/16 F02C9/26 

FIELD: gas turbine engines.

SUBSTANCE: control system of a gas turbine engine relates to engine building, mainly to systems for supplying cryogenic fuel to a gas turbine engine based on land and vehicles. Objectives of the invention: expanding the range and reliability of the system for regulating the operating modes of a gas turbine engine with a closed cryogenic fuel supply system by changing the total heating of gaseous cryogenic fuel supplied to the gas turbine of the turbopump unit. The tasks set in the fuel control system of a gas turbine engine mainly for the supply of cryogenic fuel, containing a pump for its supply, connected in series through a flow regulator, a heat exchanger-gasifier installed in the nozzle of a gas turbine engine, a gas turbine for driving a pump, a shut-off valve with a nozzle rail in the combustion chamber of a gas turbine engine, while the flow regulator is connected to the control unit, are solved by the fact that the heat exchanger-gasifier consists of separate parallel sections, at the inlet, each of which is equipped with a flow regulator, and the outputs from separate parallel sections of the heat exchanger-gasifier are connected to the inlet of the drive gas turbine pump.

EFFECT: invention has improved the control system of a gas turbine engine, in which the heating of cryogenic fuel is optimized to ensure the appropriate operating modes of the gas turbine engine, while there is no external additional energy consumption for the pump drive for supplying cryogenic fuel, and the evaporation of cryogenic fuel is necessary in any system of its supply.
