Z-pinch Discharge in Laser Produced Plasma
Z-pinch effects in a laser produced aluminium plasma were investigated with a relatively low current fast coaxial electrical discharge. The ion flux in the laser produced plasma (LPP) was monitored with a Langmuir ion probe and the line density was controlled by using an aperture to select the portion of the LPP which enters the discharge cell. The Zpinch dynamics were recorded using time-resol...
متن کاملEndurance testing of a pulsed plasma thruster for nanosatellites
The mission complexity of Nanosatellites has increased tremendously in recent years, but their mission range is limited due to the lack of an active orbit control or Δv capability. Pulsed Plasma Thrusters (PPT), featuring structural simplicity and very low power consumption are a prime candidate for such applications. However, the required miniaturization of standard PPTs and the adaption to th...
متن کاملPulsed Plasma Thruster Systems for Spacecraft Attitude Control
Pulsed Plasma Thrusters (PPTs) are finding renewed user appeal due to the growth in small satellite applications. PPTs are especially well suited to small satellite applications because they are simple, low-mass, and high Isp propulsion systems. The solid Teflon fuel allows for a self-contained, inert and stable propellant system. With a power draw of only 0.1 to 150 W and a very small (50 800 ...
متن کاملDevice and Plume Model of an Electrothermal Pulsed Plasma Thruster
Progress in combined device/plume modeling is presented for a Teflon-fed, pulsed plasma thruster from plasma generation to the plume far field. In this work we apply a one-dimensional unsteady model for the plasma generation and acceleration process. A new kinetic ablation algorithm is employed to calculate the Teflon ablation rate as a function of plasma parameters. A near cathode sheath model...
متن کاملModeling of a Pulsed Plasma Thruster; Simple Design, Complex Matter
Experiments conducted at the Surrey Space Centre on a breadboard pulsed plasma thruster (PPT) have led to greater insights in to the underlying principles of electrode erosion during plasma formation. It has been shown that during a PPT discharge a significant proportion of the plasma that is produced is from direct erosion of the electrodes to the extent that traditional Teflon propellant bars...
