SYSTEM FOR CONTROLLING THRUST VECTOR OF LIQUID-PROPELLANT ENGINE Russian patent published in 2016 - IPC F02K9/82 

FIELD: engines and pumps, rocket engineering.

SUBSTANCE: invention can be used in systems of controlling thrust vector in rocket engines operating on liquid fuel with different schemes for organisation of working process. Thrust vector control system for liquid-propellant engine, consisting of manifold, pipelines and gas-dynamic control elements, comprises eight gas-dynamic control elements, each of which is a valve, through which gas is supplied into nozzle. Valves are arranged uniformly in pairs on outer surface of supersonic portion of nozzle supersonic in gas injection plane, perpendicular to longitudinal axis of nozzle. Valves in two pairs are symmetrical to pitch plane, while two other pairs are symmetrical to yaw plane. In each pair, axes of valves axis intersect at an angle 40°÷60°, and their intersection point is located at distance 1/3R…2/3R from centre of circle formed by intersection of nozzle inner surface with plane of gas injection, where R is radius of this circle.

EFFECT: invention provides control of thrust vector of liquid-propellant engines on pitch, yaw and bank, using one control system.
