METHOD OF LOW-THRUST ROCKET ENGINE OPERATION Russian patent published in 2017 - IPC F03H99/00 

FIELD: engine devices and pumps.

SUBSTANCE: in method of operation of low-thrust rocket engine containing a heating chamber, a nozzle, a high-frequency current source, a control unit, a working medium supply system to a heating chamber and a cooling system, including feeding of working medium into a porous insert located inside the heating chamber, heating the porous insert with use of high-frequency current energy, efflux of working medium through nozzle, the new one is that water is used as working medium, at that the value of the pressure before the porous insert is set depending on the consumption of the working medium and the porosity of the insert of at least 1000 bar, in the first stage of water flow in the porous insert, water is transformed into steam, in the second stage superheated steam is obtained, in this case, superheated steam flows through the nozzle. The porosity of the insert is preferably set from P=0.02 to P=0.2.

EFFECT: improvement of safety, reduction of power consumption and cost in operation of the engine.
