Stabilized Liner Implosions Driven by Axially-Moving Free-Pistons.

Abstract

The use of axially-moving free-pistons to drive rotating liquid liners is described. The advantages of this approach include simple synchronism of piston motion to avoid low frequency Rayleigh-Taylor instability, a great reduction in the number of moving parts, and excellent azimuthal symmetry. Initial experimental results are presented which demonstrate stable, repetitive implosion-reexpansion cycles using a hydrodynamic scale-model. Further developments are also indicated. (Author)
