“…Electrostatic spraying has shown success in recent years when it comes to creating thin films, enhancing surface characteristics, electrostatic printing, creating nanoparticle powder, electric propulsion, and so on [5][6][7][8]. Electrostatic spraying is frequently used in space electric propulsion because accelerated heavy droplets can create a higher thrust density than lighter ions [9][10][11][12]. The Ultrasonic Electric Propulsion (UEP) system is a cutting-edge utilization of electrostatic spraying in electric propulsion.…”

The Ultrasonic Electric Propulsion (UEP) system is a cutting-edge propulsion technology that is mostly used on platforms for small satellites (less than 10 kg). The characteristics of droplet partial emissions (DPEs) in the UEP system are investigated using a high-speed imaging technique (an ultra-high speed camera (NAC HX-6) and a long-distance microscope) in this work. The experiments demonstrate that there are a few partial emission modes, including left-side emission, double-side emission, and right-side emission, that are present in the droplet emission process of the UEP system. These modes are primarily caused by the partial formation of capillary standing waves (CSWs) on the emission surface of the ultrasonic nozzle. The emission rate for single- and double-sided emissions varies at different times, indicating that there are different CSWs engaged in droplet emission due to variations in the liquid film thickness and charge state of the liquid cones. Additionally, as the droplets emit continuously, a raised area on the emission surface appears, with several droplets emitting there as a result of charge accumulation. Additionally, photos of the CSWs with emitting droplets are obtained, which highlights the CSWs’ distinctive wave morphology.

“…Одной их новых актуальных задач, стоящих перед космической отраслью, является организация полетов космических аппаратов на сверхнизких околоземных орбитах (∼ 200 km) [1][2][3][4]. Наличие остаточной атмосферы на высотах порядка 200 km требует оснащения космических аппаратов двигателями, способными долговременно работать не только на инертных газах, но и на их смесях с воздухом, а в идеале -исключительно на воздухе.…”

The work presents the results of an experimental study of the characteristics of the RF capacitive discharge placed in a magnetic field with a predominant radial component. The experiments are performed in the plasma source, which has the geometry of a Hall thruster. The integrated characteristics of the discharge, as well as the axial distribution of the probe ion current in the channel of the plasma source, are measured using three diagrams of the organization of the external discharge circuit: with the open for DC discharge circuit, as well as in the combination of a capacitive discharge with a direct current discharge. The main measurements are made in the argon in the flowrate range of 0.75 - 1.8 mg/s and the power of the generator 80 - 300 W at a frequencies of 2, 4 and 13.56 MHz, the induction of the magnetic field lying in the range of 100 - 300 G. Evaluation of the parameters of the plasma engine based on capacitive RF discharge when working in air, argon and krypton are made.
