ABSTRACT:
An explosive auto-enhancement device for providing higher detonation pressure than can be achieved with conventional explosives by the use of magnetic precompression for enhancing the detonation wave. A cylindrical armature containing an explosive charge is coaxially spaced within a helical field generator winding with a first end of the armature being electrically coupled to the helical winding. A "seed" magnetic field is provided to the helical winding prior to the initiation of the explosive charge. When the explosive charge is initiated, forming a detonation wave, the other end of the cyclindrical armature expands and is coupled to the helical winding, thus completing the electrical circuit between the winding and the armature. As the detonation wave continues through the explosive charge, more of the coils of the helical winding are short circuited which reduces the inductance and results in increased magnetic flux within the winding. A magnetic pressure appears ahead of the detonation wave due to the increased magnetic flux and compresses the undisturbed armature and contained explosive, causing the detonation wave to increase in velocity and pressure. The detonation wave is thus continually accelerated by the generation of magnetic pressure preceeding the detonated explosive wave.
