摘要
A plasma-propellant interaction experiment ''PIPE'' has been constructed to investigate the plasma-propellant interface physics, and plasma augmentation to the propellant burn rate. The experimental facility consists of an electrothermal plasma source that injects plasma to the surface of solid or liquid propellants. The source (ET) is powered by a 340 mu F Maxwell capacitor (17 kJ at 10 kV, up to 100 kA, 400 mu s pulse duration) via a pulse forming network (PFN). Experiments with JA2 granular solid propellant under vacuum operation (20 Torr base pressure) showed incomplete burn of the propellant. However, the overall chamber pressure is a factor of two higher than,that without propellant. Preliminary measurements showed that the burn rate with plasma injection has been increased by a factor of three at a pressure of 0.7 kbar compared to conventional ignition.
