MULTIPOINT INITIATED IMPLOSIONS FROM HEMISPHERICAL SHELLS OF SHEET EXPLOSIVE.

Abstract

Some preliminary results are given on the generation of implosion waves by simultaneously detonating a hemispherical shell of sheet explosive at 91 individual initiation sites. The 7 in. dia. x 0.168 in. thick shell was formed from eight 'orange-peel' segments cemented on a steel backing shell 0.1 in. thick, which was perforated to take the 91 detonators. A scalloped type shock wave surface was generated from the 91 individual detonation sites that imploded into the gas space. The distortions of the shock wave surface increased as the implosion wave gained in strength while converging on the origin. It would seem from the limited experiments that this may not be a useful way of producing implosions. However, it appears to be a useful method of investigating instabilities of implosion waves arising from controlled disturbances.
