Journal ArticleDOI
Plasma generation using high-power millimeter-wave beam and its application for thrust generation
TL;DR: In this article, an ionization front in the beam channel was observed after plasma was generated using a 170GHz millimeter-wave beam in the atmosphere, and the propagation velocity of the front was found to be supersonic when the power density was greater than 75kWcm−2.
Journal ArticleDOI
Discharge Current Oscillation in Hall Thrusters
TL;DR: In this paper, the discharge current oscillation at a frequency range of 10-100 kHz in Hall thrusters was investigated with the objective of extending their stable operational range, and the oscillation amplitude was found to be sensitive to the applied magnetic flux density.
Journal ArticleDOI
Development of thrust stand for low impulse measurement from microthrusters
TL;DR: In this article, a data analysis method to reduce the effect of mechanical noise is proposed by introducing an additional term in a fitting function, which is verified that the analysis method used in their experimental conditions reduced variance caused by noise down to one-third that of a normal fitting method.
Journal ArticleDOI
Two-dimensional numerical model of plasma flow in a Hall thruster
TL;DR: In this paper, a two-dimensional numerical model of plasma flow in a Hall thruster has been made to estimate analytically the ion-loss flux to the walls of an acceleration channel, and to obtain information about desirable configurations for good thruster performance.
Journal ArticleDOI
Plasma acceleration processes in an ablative pulsed plasma thruster
TL;DR: In this paper, an ablative pulsed plasma thruster (APPT) was investigated and it was shown that high density, ablated neutral gas stays near the propellant surface, and only a fraction of the neutrals is converted into plasma and electromagnetically accelerated.
