Abstract

The ejection of particles from the free surface of metal liners accelerated to velocities of 4–5 km/s using explosive energy has been investigated. It is shown experimentally that the effect of shock-wave dusting can be suppressed by quasi-isentropic or isentropic loading of liners during their acceleration. [ABSTRACT FROM AUTHOR]

Abstract

This paper presents the results of an experimental study of particle ejection into low (0.05 atm) vacuum from a narrow (0.2-0.8 mm) rough (Rz = 20-50 μm) surface of a lead sample subjected to a shock wave of intensity about 17 and 34 GPa. The ejecta was recorded with a video camera in the microscopic mode with short laser irradiation. Due to the small optical thickness of the ejecta, particle spectra at approximately 80% of the ejecta height measured from the front of the ejecta were obtained. It was found that when lead is in the solid state (17 GPa), jets consisting of a lot of particles are ejected from the rough surface; when the lead is in the liquid state (34 GPa), a lot of thin (from 7 μm) microcumulative jets are ejected from the metal surface, and with time they break up into particles.
