Abstract

Applied-physics and theoretical foundations are discussed to generate unipolar electric charge in electrostatic source of liquid particles for colloid electrojet engine. Liquid working medium of the engine is investigated as cold electrolytic plasma. A decompensation of spatial charge for electrolytic ions as well as generation of unipolar electric charge takes place in the plasma upon action of strong electric field. An analytic solution is suggested to solve a calculation problem for specific charge of the particles depending on liquid properties, spraying electrode polarization, field parameters and consumption of working medium. A comparison for calculated and experimental data is carried out.
