FIELD: space engineering. SUBSTANCE: invention relates to systems of space craft electric rocket plants on base of stationary plasma jet engines. Said system contains working medium storage system 1, working supply unit 2 consisting of receiver 6, control valve 9 and potentiometer-type pressure transducers 8, supply and control system 3 including pressure amplifier-regulator 10 and at least one stationary plasma engine 4. Outlets of pressure transducers 8 are connected with inlet of pressure amplifier-regulator 10, and outlet of pressure amplifier-regulator 10 is connected with inlet of control valve 9, additional resistor 12 is installed in "+" supply circuit of each pressure transducer 8. Resistance of said additional resistor is chosen to provide following equality: where Rpreset rel, %, is preset output relative resistance; Rout 1, Rout 2, Rout 3 is resistance between middle point and "-" supply circuit of corresponding pressure transducer; Rp 1, Rp 2, Rp 3 is resistance of potentiometer of corresponding transducer; Rad 1, Rad 2, Rad 3 is resistance of additional resistor of corresponding pressure transducer. Invention makes it possible to provide unification of supply and control system and working medium supply unit and interchangeability of units. EFFECT: reduced time taken for manufacture of propulsion system. 2 dwg
