Pulsed Plasma Thrusters for Small Satellites
Since the Russian launch of the Zond-2 satellite in 1964 there have been over fifty years of research dedicated to the understanding of the first electric propulsion device to be flown in space, the Pulsed Plasma Thruster. The Pulsed Plasma Thruster originates from the evolution of the vacuum arc switch, but due to its microsecond operation time, the internal dynamics and nature of operation ha...
متن کاملPulsed Plasma Acceleration Using Powdered Propellant
Pulsed plasma thrusters (PPTs) are the simplest electric acceleration devices with solid propellant on satellites. In order to make their thrust performance higher and to feed propellant more effectively, we have been developing a new type PPT using powdered propellant. To estimate its thrust performance, we have made a test model thruster for comparing the thrust performances of PPTs with soli...
متن کاملCurrent Sheet Permeability in Electromagnetic Pulsed Plasma Thrusters
A case is made for the existence of permeability of current sheets in electromagnetic pulsed plasma thrusters. Permeability refers to the leakage of plasma or neutral particles behind the sheet and could cause a significant effect on the performance of the thruster. Analytical calculations are presented which demonstrate the mismatch between experimental velocity profiles and theoretical snowpl...
متن کاملDimensionless Performance Model for Gas-Fed Pulsed Plasma Thrusters∗
We present a non-dimensional gas-fed pulsed plasma thruster performance model. The analysis uses a circuit element discharge description and a snow-plow mass accumulation model with two non-dimensional parameters for an outer electrode geometry contour and an exponential mass distribution. Implementing a non-dimensional scheme is shown to reduce the number of free parameters in the equations fr...
متن کاملLaser Discharge Initiation for Gas-fed Pulsed Plasma Thrusters
A method of discharge initiation at an undervoltage by a laser-induced pulse of electrons from a photocathode is presented. The intended application is to produce spatially uniform current sheet initiation in gas-fed pulsed plasma thrusters. The effect is explained by a space charge buildup which can increase the electric field of the gap. A theoretical model was developed and showed that an in...
