Plasma Opening
Switches NumerEx has used a
variety of simulations delveloped in-house and elsewhere to gain insight in the
workings of plasma opening switches. These including the Magnetically Injected
plasma opening switch and the Current Toggled plasma opening switch. Rail Guns NumerEx has modeled
the radiatively-driven ablation of wall material, allowing the first
self-consistent prediction of the total mass of the arc plasma to be made. The
simulations were also the first to reveal a convective flow pattern in the arc
driven by a transverse density gradient and the arc/projectile acceleration. Anode Layer Thruster NumerEx has experience
simulating plasma hall thrusters, including the Russian Stationary Plasma
Thruster and the Anode Layer Thruster. These thrusters are candidates for
satellite station-keeping because of their high specific impulse, compact size,
high payload mass fractions, and long life.
