FIELD: aircraft engineering; gas-turbine engines.
SUBSTANCE: invention can be used in automatic control electronic hydromechanical systems of gas-turbine engines. According to invention, change-over device is introduced additionally into system whose first input is connected to output of electronic regulator, second input is connected through restrictor to output of low-pressure electric pump, and third input is connected to output of high-pressure electric pump, and output is connected to input of shutoff valve of first manifold of combustion chamber of gas-turbine engine. Such design of system improved reliability of engine owing to use nozzle on starting section of gas-turbine engine low-pressure pump to supply first manifold which provides required fuel delivery into combustion chamber of gas-turbine engine without additional metering out devices.
EFFECT: improved reliability of gas-turbine engine in operation.
