Abstract

The method of controlling the software rotation of the accelerating unit using stationary engines of constant thrust orientation, which consists in performing a set of angular velocity - acceleration, inertia, reducing the angular velocity to zero - braking and switching on the orientation engines when the angular velocity decreases below a predetermined level, characterized in that in the case of the implementation of a software reversal, combined in time with the operation of the preload engines, before the reversal, the level h of the most affecting dyne is measured the turn of the fuel component in the tank, and during the turn, the mismatch in the angle Δ углу and the angular velocity of the upper stage of the upper stage, the angle s and the angular rate of deviation of the surface of the specified component of the fuel in the tank from the longitudinal axis of the upper stage, are measured at the end of the acceleration section when when parameter x reaches ƒ (x '), the inclusion of orientation motors at the beginning of the braking section is performed when parameter x reaches ƒ (x'), where; - the functions are switched ia, and the parameters x and x 'are set in the form of linear functions of the measured angles and angular velocities x = k (kΔs + ks), with coefficients k, k, k determined by pre-calculated dependences on the level h of the fuel component in the tank.
