SPACECRAFT MOTION CONTROL DEVICE Russian patent published in 1998 - IPC

FIELD: space engineering; change or stabilization of orbit parameters and orientation of spacecraft. SUBSTANCE: proposed device includes control systems for control of motion about center of mass of spacecraft and motion of center of mass of spacecraft; used as actuating members of both systems are the same electric rocket engines with deflectable vectors of thrust. Functional decoupling between these systems is effected by means of engine-flywheels which also integrate disturbing moments; for unloading the engines-flywheels, provision is made for adjustment (through control unit) of direction of thrust of electrical rocket engines mainly made in form of plasma accelerators with closed drift of electrons and provided with control magnetizing coils connected to this unit and additional control poles. EFFECT: reduction of mass and enhanced reliability of engine plant. 4 cl, 2 dwg
