FIELD: rocket construction.
SUBSTANCE: invention relates to rocket engineering, particularly to a liquid-propellant engine with a nozzle. In liquid propellant engine actuating mechanism is in form of two, coaxial with fixed nozzle and to each other, one fixed and the other, made with possibility of rotation relative to fixed shell arranged between shells of bearings and unit of limitation of mutual axial movement along longitudinal axis of nozzle, and at second shell kinematically linked with drive rotary movement via a kinematic assembly, and on external part arranged to move part of nozzle uniformly in circumferential direction there are pins having at their ends spherical bearings connected by connecting rods.
EFFECT: invention ensures reduction of dynamic loads on nozzle during extension at final section, as well as reduced radial dimensions and weight.
