HIGH-EFFICIENCY TYPE EXPLOSIVE GENERATOR

PURPOSE:To get a high-efficiency type explosive generator by continuously changing the quantity of charged explosive so that the quantity of charged explosive may be small at start of explosion of an explosive and maximum at the end of explosion when the condensation of a magnetic field is maximum. CONSTITUTION:In the case of a coil-type generator, a spacer 9 is inserted in the center of the generator 1, and an explosive 8 is charged around it. And, the material of the spacer 9 is an inert resin such as acrylic resin, and the shape is conical. Accordingly, the quantity of explosive charged between the spacer 9 and the inwall of an armature 1 is becomes larger continuously from the starting point of explosion where a triggering device 5 exists to the end point of explosion. As a result, the quantity of explosive per unit length in advance direction of explosion becomes larger gradually, and it can enough exhibit the compressive force surpassing the force of resisting the reduction of a gap 2, so the quantity of explosive can be saved as compared with a conventional explosive, and a high-efficiency type explosive generator capable of efficient power generation can be gotten.
