FIELD: space.
SUBSTANCE: invention relates to the methods for space rocket (SR) movement control. Method for control of SR angular motion consists in control of pitch and yaw angles by deviation of the main engine combustion chamber arranged in the gimbal suspension in two mutually perpendicular planes, in control of banking angle by means of two pairs of gas nozzles and two aerodynamic rudders inclined by means of their electrohydraulic servos (EHS). Mismatch between command signal for deviation of aerodynamic rudders and actual angles of their deflection is determined. If any of two mismatch absolute values exceeds the preset maximum permissible value, an aerodynamic rudder EHS fault flag is generated. In case of EHS fault flag generation, the main engine combustion chamber is additionally deflected by pitch and aerodynamic rudder with serviceable EHS, yaw angle is additionally controlled by means of pairs of gas nozzles.
EFFECT: technical result is high probability of successful completion of RS flight in case of failure of one of the actuators of control system.
