Abstract

An experimental,research program designed to evaluate the effect of a weakly ionized gas on a propagating shock wave is described. This research was performed in a “large” diameter (4”) shock tube at “near” room temperature (314 K) in 20 Torr Helium, usjng an acoustic pressure se&or to measure the intensity of the shock wave. The initial results from this program indicate that the intensity of the shock is reduced by 25-50% when the Helium is weakly ionized, with ionization fractions on the order of 10-8, while no significant changes in the shock propagation speed are observed.
