Abstract
A donor charge detonator is disclosed which has a donor charge case for caining a main explosive with means for initiating the main charge of explosive. The case design comprises a plurality of flutes formed around the outer surface of the case, and the plurality of flutes comprise valley members or grooves separated by peaks between successive grooves. The grooves and peaks of the flutes function after initiation of the main charge of explosive to cause the formation of particles from the donor charge case and the resulting explosive force to follow along the valleys of the flutes thereby forming a plurality of jets similar to linerar lines whereby the resulant shock is enhanced in a specific direction. The resulting force and the resultant shock are transferred at a higher magnitude because of the jet effect of the fluted configuration of the donor charge case. The specific direction is directed to a point on an explosive acceptor charge when in combination therewith to achieve a greater output and efficiency as compared with spherical shock waves and particle velocities from a conventional detonator.
