| 101 | Rotating and oscillating breaching device with reactive material | US14444655 | 2014-07-28 | US09175938B2 | 2015-11-03 | Darrel Barnette; Eric Bleicken |
| A breaching device for non-explosively cutting through a substrate, such as the leg of an offshore oil platform or other large cylinder from within the leg or large cylinder. The device includes a ring and a plurality of Reactive Material (RM) feed assemblies. Each RM feed assembly is arranged around the ring and includes an extendible nozzle. Each RM feed assembly includes a cavity that may contain RM that when ignited exits the nozzle. The nozzles are spring loaded and arranged to extend toward the inner surface of the substrate to be cut when the ring is rotated and/or oscillated. This arrangement results in a substantially uniform cut of the substrate from within with much less danger, material, equipment and cost than is currently required to remove large water-based structures. | ||||||

| Container (10) is generally cylindrical except for a longitudinal concave groove (11) extending along its entire length. Upon explosion, the contour of this groove (11) results in a focussing effect on the wall material due to the oblique angle at which the expanding cylindrical detonation wave front impacts upon its inner wall. This produces the forging of a rough rod-like projectile (111) which, being coherent, maintains its velocity and consequently travels much further than the randomly shaped projectiles (101). | ||||||

| A munition according to a preferred embodiment can include a detonator system having a detonator that is selectively coupled to a microwave source that functions to selectively prime, activate, initiate, and/or sensitize an insensitive explosive material for detonation. The preferred detonator can include an explosive cavity having a barrier within which an insensitive explosive material is disposed and a waveguide coupled to the explosive cavity. The preferred system can further include a microwave source coupled to the waveguide such that microwaves enter the explosive cavity and impinge on the insensitive explosive material to sensitize the explosive material for detonation. In use the preferred embodiments permit the deployment and use of munitions that are maintained in an insensitive state until the actual time of use, thereby substantially preventing unauthorized or unintended detonation thereof. | ||||||

| A high impulse fuze booster includes a booster explosive charge positioned within an explosive charge cavity of a booster housing. A substantially planar flyer plate is coupled with the booster housing, and a detonation waveshaper is positioned within the booster explosive charge. A low-sensitivity explosive charge is opposed to the substantially planar flyer plate. The booster explosive charge is configured to generate a detonation wave and the detonation waveshaper shapes the detonation wave into a planar detonation wave, the planar detonation wave is parallel to the substantially planar flyer plate. The planar detonation wave interacts with the substantially planar flyer plate in two or more stages including a planar striking stage and a planar contact stage where the planar detonation wave carries the substantially planar flyer plate into planar contact with a plurality of surfaces of the low-sensitivity explosive charge to initiate the low-sensitivity explosive charge. | ||||||

| A method for initiating a low-sensitivity explosive charge includes initiating a booster explosive charge within an explosive charge cavity in a booster housing, and generating a planar detonation wave. Generating the planar detonation wave includes directing a detonation wave through the booster housing along a first waveshaper surface of a detonation waveshaper. The detonation wave is directed around the first waveshaper surface toward a second tapered waveshaper surface. After progressing around the first waveshaper surface, the detonation wave is directed along the second tapered waveshaper surface. The detonation wave changes into a planar detonation wave as the detonation wave moves along the second tapered waveshaper surface, the planar detonation wave includes a planar wave front. The planar detonation wave strikes a flyer plate coupled over the explosive charge cavity of the booster housing, and the planar wave front makes planar contact along an inner face of the flyer plate. | ||||||
| 110 | Warhead booster explosive lens | US12985970 | 2011-01-06 | US08037822B2 | 2011-10-18 | A. Russ Althof; William R. Hawkins; Henri Y. Kim |
| A cost-effective solution is proposed to improve explosive transfer between booster and warhead that is compatible with the existing base of general purpose warheads and flexible to work with new warhead configurations. A booster lens is placed in the fuze well that concentrates the pressure wave to penetrate the fuze well with a peak pressure that exceeds the detonation threshold and detonate the warhead explosive. The booster lens can be configured to control the direction of the concentrated lobe to penetrate the fuze well where the barriers are low. | ||||||

| 117 | Method and apparatus for controlled small-charge blasting by decoupled explosive | US09710497 | 2000-11-10 | US06435096B1 | 2002-08-20 | John David Watson |
| A cartridge containing an explosive charge is inserted at the bottom of a short hole drilled in the rock. The cartridge is held in place or stemmed by a massive stemming bar of high-strength material such as steel. The cartridge incorporates additional internal volume designed to control the application of pressure in the bottom hole volume by the detonating explosive. The primary method by which the high-pressure gases are contained in the hole bottom until relieved by the opening up of controlled fractures, is by the massive inertial stemming bar which blocks the flow of gas up the drill hole except for a small leak path between the stemming bar and the drill hole walls. The stemming bar is preferably connected to a boom mounted on a carrier. A preferred embodiment incorporates an indexing mechanism to allow both a drill and a small-charge blasting apparatus to be used on the same boom for drilling and subsequent charge insertion and firing operations. | ||||||
| 118 | Explosive diode transfer system for a modular perforating apparatus | US718494 | 1991-06-19 | US5216197A | 1993-06-01 | Klaus B. Huber; Antoni K. L. Miszewski |
| An explosive diode transfer system is interconnected between adjacent perforating guns of a modular perforating apparatus. The explosive diode transfer system includes a downwardly directed shaped charge, a booster, and a multi-density barrier interposed between the shaped charge and the booster. The multi-density barrier includes a first metal layer and a second metal layer spaced from the first metal layer thereby defining a sealed air-space between the first and second metal layers. The first metal layer, air space, second metal layer combination represents a plurality of different density barriers or layers which are collectively designed to prevent a first detonation wave, propagating from the booster to the shaped charge, from propagating therethrough, but nevertheless to allow a jet, propagating from the shaped charge to the booster, to propagate therethrough. The multi-density character of the barrier and the air space reflect and therefore completely attenuate the first detonation wave as it propagates from the booster to the shaped charge, but does not significantly attenuate the jet propagating from the shaped charge to the booster. Therefore, the explosive diode transfer system functions like a diode, allowing propagation in one direction, but not allowing propagation in the opposite direction. Consequently, the multi-density barrier of the explosive diode transfer system prevents a back fired detonation wave originating from a lower oriented perforating gun from detonating a higher oriented perforating gun in the modular perforating apparatus. | ||||||

| A method and apparatus are disclosed for guiding and increasing the effect of underwater detonation of an underwater explosive body, characterized in that a hollow space is defined adjacent the explosive body on the side thereof facing the target, whereby upon detonation of the explosive body, gases of high density are generated in the hollow space which are accelerated to high speed prior to meeting with the surrounding water. | ||||||
