ELECTRIC ROCKET PROPULSION SYSTEM Russian patent published in 2003 - IPC

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 R_presetrel, %, is preset output relative resistance; R_out1, R_out2, R_out3 is resistance between middle point and "-" supply circuit of corresponding pressure transducer; R_p1, R_p2, R_p3 is resistance of potentiometer of corresponding transducer; R_ad1, R_ad2, R_ad3 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
