FIELD: machine building.
SUBSTANCE: invention relates to payload launching means. Reusable stage comprises instrument compartment (1), conical tank (2) of an oxidizer and a tore fuel tank (3). Tank (3) with platform (4) fixed on rod of hydraulic cylinder (5) forms payload compartment (6). Four-chamber cruise liquid-propellant engine (LPE) (8) and steering LPE with chambers (10) are installed in engine compartment (7), which also provides for landing of the stage. Each chamber (9) of cruise liquid-propellant engine (8) can turn (fold) in one plane. Hydraulic cylinder (5) provides movement of platform (4) with payload (11) along the stage axis. Foldable landing supports (12) are fixed outside tore tank (3).
EFFECT: improved mass-dimensional characteristics of the stage.
