LIQUID PROPELLANT ENGINE WITH THRUST VECTOR CONTROL Russian patent published in 2016 - IPC F02K9/80 

FIELD: rocket science.

SUBSTANCE: invention relates to rocketry, particularly, to liquid-propellant engines with controlled thrust vector. Liquid propellant engine with controlled thrust vector comprises chamber to swing in journals in the main stabilization planes, main components on the periphery of the engine along its axis, turbo pump unit with main high-pressure pumps and booster units, outputs of the pumps which are made in the form of spiral bends with conical nozzles and are connected in the latter to inputs of the main pumps at the periphery of the chamber with two pairs of two mutually perpendicular series of flexible pipelines in the form of bellows parallel to the main planes of stabilization and connected by curvilinear branch pipes, according to the invention in charge centrifugal pumps are installed by its inputs coaxial lines of supply components, and conical nozzles outlets along longitudinal axes of symmetry of the first towards high-pressure pumps and the nearest bellows flexible pipelines, the booster pump one component is made with possibility of rotation of rotor in opposite direction from the direction of rotor rotation booster another component.

EFFECT: invention provides reduced radial dimensions of liquid propellant engine seal engine layout and thereby reduced engine weight.
