FIELD: space engineering; reusable space vehicles with engine plants whose propellant tanks are used for performing additional (in addition to main function) function, for example for deceleration of vehicles during flight in atmosphere. SUBSTANCE: propellant feed system is provided with collector ring secured on tank attachment frame; hollow axles of articulated swivel tank attachment units are located concentrically relative to collector ring; they have free ends for rotation in inner surfaces of this collector ring; articulated units are located in tail sections of tanks; cavities of swivel axles are communicated with propellant service mains fitted with cut-off valves. EFFECT: enhanced reliability; reduced mass of system when tanks are used for aerodynamic braking of space vehicle after utilization of fuel. 2 cl, 3 dwg
