Rotational Stabilization of the Inner Surface of a Piston-Driven Imploding Liner.

Abstract

The use of rotation to stabilize the inner surface of a liquid liner compressing a gas payload is studied experimentally. The outer surface of the liner is driven by a plurality of radially-displaced free-pistons to eliminate high frequency Rayleigh-Taylor instability at the outer surface, with the entire implosion mechanism rotating to provide angular momentum to stabilize the inner surface. Both stable and unstable inner surfaces are observed during final payload compression. Excellent correlation of observed behavior with theoretically predicted performance is obtained, providing confidence in the use of rotation to eliminate Rayleigh-Taylor instability at the inner surface of a liner compressing a lower density payload.
