Control means of thruster units on stationary plasma thrusters base as sustainer and traction thrusters of space craft

Are considered control means of thruster units (TU) on base of stationary plasma thrusters (SPT), used as sustainer and traction thrusters of the Space Craft (SC) under power supply from solar battery (SB) directly, generated power its is changed in large range. Supply and control systems of TU are differed importantly from used earlier in the SC orbit correction systems. In this case a new problem is solved: either supplying with thruster.s maximum traction or maximum using of SB power. It is reached by extreme regulator, which changes expenditure of working substance (and discharge current of SPT) up to maximum SPT traction or consumption power from SB in every time. Effective consumption of working substance is ensured by stabilization of SPT anode voltage at maximum permissible level. Are offered structural-functional diagrams of SPT, realizing stated control means of TU.
