Thrusters: Ablative Pulsed, Plasma Acceleration in
ByTony Schönherr
Pages 10

As one kind of electric space propulsion systems, pulsed plasma thrusters have been subject to several decades of study. During this time, experimental studies with ablative solid-propellant pulsed plasma thrusters have revealed many aspects regarding the physical processes involving discharge current, ablation and ionization, and plasma acceleration respectively. Those aspects and a detailed summary of the experimental work leading to a deepened understanding of the processes are the scope of this entry. Finally, remaining challenges for future research are outlined.
