METHOD OF CONTROL OF BOOSTER UNIT LONGITUDINAL MOTION ON DELTA-VELOCITY MANEUVER PHASE Russian patent published in 2009 - IPC B64G1/24 G05D1/08 

FIELD: transport.

SUBSTANCE: method is designed to control booster unit longitudinal motion on delta-velocity phase wherein, after the booster unit is separated from rocket carrier, the booster unit lengthwise axis is stabilised with respect to the said axis direction at the moment of separation of the rocker carrier. The proposed method comprises reading out flying mission data on control parameters and orbit of the booster unit being set up at the delta-velocity maneuver phase, cutting in pulse correction engines at preset time intervals after separation from the rocket carrier to pre-compress fuel in fuel tanks for preset time interval and starting the sustainer. After this, in preset time and as specified in flying mission, the booster unit pitch orientation program is run and corrected with help of terminal control means, the sustainer is cut off. Before this, at preset time interval, orientation program is fixed. The booster unit separated from the rocket carrier, it is turned with respect to pitch till attaining the orientation defined by starting angle of pitch variation at the delta-velocity phase as specified in flying mission. Note that at this angle the booster unit longitudinal axis is stabilised till completion of the aforesaid orientation program.

EFFECT: power savings at delta-velocity phase.
