| (54) | Super compressed detonation method and device to effect such detonation |
| (57) A method and apparatus (20) for high pressure compression of materials and for detonation
of the compressed material by cylindrical implosion followed by an axial detonation
to a detonation velocity several times that of TNT and a detonation pressure in excess
of ten times that of TNT. The device provides a conical metal flyer shell (5) within
which is disposed a cylindrical anvil (10) surrounded by explosive (7). The anvil
(10) retains a sample material (11) to be compressed and detonated. A first detonation
of explosive by impact of the flyer shell (5) generates a reverberating oblique shock
wave system for sample compression. Axial detonation of the compressed sample (11)
through any length of a sample (11) is achieved following the principal of matching
the axial velocity and compression time of the oblique shock wave system to the detonation
rate and induction delay time of the compressed sample (11). The method and apparatus
(20) are also applicable to enhancing the effect of anti-armour and anti-hard-target
munitions. The apparatus is also applicable to inert sample compression to the megabar
range without using the axial detonation.
