Abstract:
1. A detonator, comprising: a detonator tube having a first end and a second end, said first end being a fill point and said second end being an open end, said detonator having an ignition point positioned at a substantially central point of a cross section of said detonator tube between said first end and said second end, said detonator tube being supplied a gaseous or dispersive fuel-oxidant mixture at said fill point of said detonator tube, said fuel-oxidant mixture comprising a fuel and an oxidant, a predetermined mass ratio of said fuel versus said oxidant and a predetermined flow rate of said fuel-oxidant mixture being maintained to achieve detonation characteristics, said detonation characteristics depending on length and diameter characteristics of said detonator tube, said gaseous or dispersive fuel-oxidant mixture flowing through said ignition point from said fill point of said detonator tube; and an igniter, said igniter being placed at said ignition point within said detonator tube, said igniter igniting said gaseous or dispersive fuel-oxidant mixture at said ignition point while said gaseous or dispersive fuel-oxidant mixture is flowing at said predetermined flow rate through said ignition point within said detonator tube thereby producing a detonation impulse substantially at said ignition point that propagates to said open end of said detonator tube.
