FIELD: rocketry. SUBSTANCE: engine plant with gas-dynamic control members includes passages supplying fluid medium to surfaces washed with gas flow and solenoid-operated control valves. Electro-or magneto-rheological fluid containing paste0like propellant in the amount of up to 95 mass-% may be used as fluid medium and electro- or magnetorheological chokes may be used as solenoid-operated valves. Electro- or magneto- rheological fluid may be placed in cavity of plant housing and fluid supply passages may be matched with parting surfaces of housing and nozzle and may be made in form of slotted bows or ring. Electro- or magnetorheological chokes may be made with common electrode or magnetic circuit. Passages for supply of electro- or magneto- rheological fluid may be fed from separate reservoirs. EFFECT: enhanced efficiency of engine plant due to use of electric and/or magnetic-rheological effect. 4 cl, 4 dwg
