FIELD: transport. ^ SUBSTANCE: invention relates to rocketry and may be used in designing optimum programs for control over space rocket first stage descent proceeding from softened restrictions related with fall of ejection stages onto existing land disposition zones. Proposed method comprises forecasting location of ejection stage fall, comparing forecast coordinates of fall point with coordinates of allowed fall zone, and estimating fuel residues in tanks. After ejection-stage separation, pulse is applied to center of gravity of said stage, its magnitude and direction being defined subject to possible variation in inclination of trajectory of space rocket descent orbit. To allow increase in velocity of ejection stage center of gravity for descent in preset area, onboard self-contained drift system is used using liquid-propellant residues in tanks. ^ EFFECT: higher payload weight in descent in existing fall zones. ^ 1 dwg |
