METHOD OF DESCENDING SEPARATED SPACE ROCKET STAGE AND DEVICE THEREFOR Russian patent published in 2016 - IPC B64G1/26 B64C15/14 

FIELD: astronautics.

SUBSTANCE: invention relates to aerospace engineering and can be used during a descent of a space rocket stage separation part (SRSSP). SRSSP comprises a control and navigation system, a fuel compartment, a system of gasification of liquid fuel residues, 2 opposite to each other discharge nozzles and piromembranes. SP is stabilized in statically stable position; use is made of energy based on gasification of liquid residues of unused components of rocket fuel and there is ensured an angular position in space corresponding to the minimum angle of attack during entrance in dense atmosphere; there is performed and aerodynamic maneuver, ensured control of movement of SP centre of mass and around the centre of mass separation by separate discharge of products of gasification (PG) from fuel and oxidizer tanks via adjustable nozzles of gas-reactive system (GS) and performed a non-momentary discharge of remaining gasification products from tanks through GS discharge nozzles.

EFFECT: invention allows to increase accuracy of SP stabilization at standard perturbations, reduce the weight and size of the system of PG utilization and SP oscillation frequency.
