FIELD: mechanical engineering; gas-turbine engines.
SUBSTANCE: invention relates to automatic control system of gas-turbine engine. Proposed system contains pumping unit connected with adjustable drive equipped with control unit. Flow rate meter made in form of servopiston with constant pressure differential valve on servopiston and position pickup are installed in output main line of pumping unit. Control space of servopiston is coupled with control space of constant pressure differential valve, and throttling section of servopiston, with sensitive elements of constant pressure differential valve. Position pickup can be made in from of electrical or optical device. Drain valve with control eletromechanical actuator can be installed in output main line of pumping unit. Such design of flow rate meter increases accuracy of measurements owing to increased resetting forces and reduced friction forces.
EFFECT: improved operation reliability.
