FIELD: liquid-propellant rocket engines.
SUBSTANCE: flow control system (22) comprises fuel channel network (34), comprising first (36) and second (38) parts of the network arranged relative to each other with possibility of parallel flows on them. In the first part of the network there is a fuel hydraulic device (40). During operation of the fuel hydraulic device the flow through the first part of the network is changed. Stream-limiting diaphragm (42) is arranged in fuel circuit network in series relative to fuel hydraulic device and upstream thereof. Flow restricting diaphragm is configured to generate pressure drop depending on the flow through the first part of the network. In the second part of the network there is a flow control valve (44). Flow control valve is configured to control flow through the second part of the network depending on the pressure drop on the flow-limiting diaphragm.
EFFECT: disclosed is a flow control system with a network of parallel connected fuel channels.
