Характеристики двигателя с анодным слоем зависят от используемого рабочего тела.При переходе традиционно применяемого и хорошо изученного ксенона к другим рабочим телам необходимо знать, как изменяются основные параметры
The paper considers the application of Hall thruster using ambient atmospheric air for orbital station keeping. This is a relevant direction at up-to-date development stage propulsion systems. Many teams designers electric rocket thrusters evaluate different schemes particle acceleration low-earth orbit. Such technical solution allows us to abandon storage systems working agent on spacecraft board. Thus, lifetime such system orbit wouldn`t be limited by fuel range. suggests scheme device...
This paper presents the results of comparison characteristics a laboratory model single-stage anode layer thruster operating with krypton and xenon. The was optimized for xenon operation. studies were carried out at flow rate propellant discharge voltage, which provide approximately equal calculated thrust on estimated using ion current beam measurements data. generated by beam. measured Faraday cylinder. power ranged from 800 to 1200 W, voltage 250 V. current-voltage are presented, as well...
Ambient air is one of the perspective propellants for electric thrusters low orbit spacecrafts. The results comparison laboratory model a thruster with closed electron drift (Hall thruster) performance are presented. was originally designed operation xenon. made xenon, and nitrogen-oxygen mixture in ratio 2 to 1. current efficiency, mass utilization efficiency power-to-thrust were chosen as characteristics. ion beam measurements also
Abstract This paper considers the study of self electromagnetic emission from experimental model low-power thruster with anode layer (TAL) developed by Bauman Moscow State Technical University. The measurements were carried out during operation on krypton and xenon for three operating modes: 600 W, 800 W 1000 at a discharge voltage 300 V. Parameters generated fields measured in frequency range 1 GHz to 12 filter bandwidth MHz. receiving antenna was installed distance m exit plane,...
In this paper, the effects of nitrogen-oxygen mixture ions on surface titanium, titanium nitride, copper and molybdenum were investigated. A magnetron spraying system was used as a device simulating impact reactive gases structural materials electric rocket engines. Effective coefficients cathode under influence nitrogen oxygen obtained, comparison with in flow argon made. Images studied after interaction ion fluxes are presented. It is shown that effective much less than
