SPACECRAFT THRUST SYSTEM Russian patent published in 2016 - IPC B64G1/40 

FIELD: motors and pumps.

SUBSTANCE: invention relates to electric propulsion systems of the spacecraft (RF). System comprises a plurality of independently controlled motors, for example, ion accelerators (TW1, TW2, TW3). Anode system (AN) of separate accelerators are connected to a common high-voltage generator (HGO) or backup generator (HGR). Formation of plasma in the ionization chamber (IK) is ensured by feeding it with a neutral working gas from the reservoir (GQ) via controllable valves (GV). Selective gas supply is provided by controlling the amount and direction of the total thrust. In the absence of plasma in the chamber the accelerator is a high-resistance element of its circuit.

EFFECT: technical result of the invention is simplification and improvement to the reliability of the propulsion system of this type.
