METHOD OF ELECTROCHEMICAL TREATMENT OF COAXIAL-SPRAY ATOMISER CHANNELS FOR CHAMBER OF LIQUID-FUEL ROCKET ENGINE Russian patent published in 2015 - IPC B23H3/10 B23H9/14 

FIELD: engines and pumps.

SUBSTANCE: invention relates to the electrochemical treatment. Method of the electrochemical treatment of the coaxial-spray atomiser channels for chamber of liquid-fuel rocket engine comprising a casing with pillars and channels for fuel components supply, includes finishing of the geometrical dimensions of the atomiser channels by the electrochemical treatment, when current conducting liquid is supplied in the treated channels using the cathode-tool. At that during treatment at the atomiser output flowrate of the said conducting liquid is registered, and electrochemical treatment is performed until achievement of the specified flowrate of the current conducting liquid through channels.

EFFECT: suggested invention ensures adjustment of the coaxial-spray atomiser for the chamber of liquid-fuel rocket engine to the specified flowrate without decreasing of the pressure drop on the atomiser.
