FIELD: aircraft engineering.
SUBSTANCE: invention can be used for control of travel of space liquid-fuelled rocket (SLFR). After the command for disabling of the mid-flight engine (MFE) of the burnt-out stage MD is switched to the reduced-thrust stage and MD is completely disabled, the rolling travel of the rocket is controlled using two pairs of gas nozzles, the moment of MD final disabling is forecasted, one of pairs of gas nozzles is enabled before the forecasted moment of MD final disabling for creation of the control rolling moment, the pair of gas nozzles are disabled at forecasted moment, and the value of the period of work of pair of gas nozzles is determined before the flight depending on the moment of inertia of the rotating part of the turbo-pump unit with the allowance for attached mass of fuel components with reference to the axis of rotation, an absolute value of the roll moment, created by each pair of the gas nozzles at their enabling, an absolute value of angular speed of rotation of the turbo-pump unit rotor at the reduced-thrust stage, angle between the axis of rotation of the turbo-pump unit rotor and the longitudinal axis of the rocket.
EFFECT: invention allows to improve safety of SLFR flight.
