In particular, mechanical initiation of the energetic composition may be achieved with significantly lower mechanical energy inputs than that typically required for initiating the monolithic energetic multilayers from which it is derived. | 07-01-2010 |
20100294156 | METHODS AND APPARATUS FOR HIGH-IMPULSE FUZE BOOSTER FOR INSENSITIVE MUNITIONS - 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. | 11-25-2010 |

20110192307 | SYSTEM AND METHOD FOR IGNITION OF A GASEOUS OR DISPERSED FUEL-OXIDANT MIXTURE - An improved system and method for ignition of a gaseous or dispersive fuel-oxidant mixture is provided where a gaseous or dispersive fuel-oxidant mixture is supplied to a detonator tube having a fill point and an open end and an igniter placed at an ignition point within the detonator tube is ignited while the gaseous or dispersive fuel-oxidant mixture is flowing through the detonator tube. A detonation impulse is produced at the ignition point that propagates to the open end of said detonator tube where it can be supplied to a detonation tube having an open end, to an internal combustion engine, a combustion chamber, and to a pulse detonation engine. | 08-11-2011 |

20120118191 | Deflagration to Detonation Transition Device - A detonator assembly is provided. The detonator assembly comprises a deflagration to detonation transition body, a first thermally stable secondary explosive contained by the body, and a bulkhead coupled to the deflagration to detonation transition body. The bulkhead contains pressure within the body associated with firing the detonator assembly at least until a transition from a deflagration operation mode of the detonator assembly to a detonation operation mode of the detonator assembly has occurred. A second thermally stable secondary explosive may alternatively be included in the deflagration to detonation transition body, either separated from the first thermally stable secondary explosive or mixed with the first thermally stable secondary explosive. The detonator assembly comprises effectively no primary explosive. | 05-17-2012 |
20120192748 | COUPLING ADAPTER - A coupling adapter including a side wall and a plurality of circumferentially spaced retaining fins supported by the side wall and extending radially inwardly in order to provide a variable diameter interference fit with an elongated member. | 08-02-2012 |
20120227607 | SHOCK DAMPENED EXPLOSIVE INITIATOR ASSEMBLY AND METHOD FOR DAMPENING SHOCK WITHIN A DELIVERY VEHICLE - Some embodiments pertain to an initiator support assembly that includes a casing and one or more initiator leads extending from the casing. The transmission of current through the initiator leads detonates an explosive charge within the casing. The casing includes a flange and a dampening member attached to the flange. The dampening member is between the flange and a structure where the initiator support assembly is mounted. The dampening member dampens shock that would otherwise be transferred from the structure to the initiator support assembly. In another example embodiment, at least a portion of the casing is formed of an interior wall, a dampening layer covering at least a portion of the interior wall and an exterior wall. The dampening layer dampens shock to the initiator support assembly that would otherwise be transferred from a structure to the initiator support assembly when the exterior wall is mounted to the structure. | 09-13-2012 |
20120240806 | Energetics Train Reaction And Method Of Making An Intensive Munitions Detonator - A detonator formed entirely from a plurality of discrete segments of an insensitive energetic composition, each of the segments employed in the detonator being compacted at different pressures from powder and/or granules of insensitive energetic composition so as to form an energetic train which sequences detonation of the individual segments. Initiation of a main charge can only be effected when a last segment in the detonation train is initiated. Detonation starts with a first segment in the detonation train which is produced under the lowest compaction pressure, and then detonation progresses to a last segment compacted under a higher compaction pressure. The first segment can be detonated by a safety fuse or detonating cord, and the last segment can only be detonated by the next to the last segment in the detonation train. | 09-27-2012 |

20140366762 | Thermal Shock Tube and the Process of Production Thereof - A spark generating tube includes a single tube and a pyrotechnical mixture. The single tube only has a single layer of plastic material, such as ethylene vinyl acetate (EVA) and polyethylene. The pyrotechnical mixture has formed a thin layer in contact with the single layer of the single tube. The pyrotechnical contains an oxidizer, a reducing agent, a substance with low temperature of Tammann and an agent for lubricating and adhering, wherein the agent for lubricating and adhering is either talc or graphite, and the reducing agent can be an aluminum powder in microscale. During the process for manufacturing a spark generating tube, the mixture of the oxidizers and additives is formed separately from the reducing agent. The final mixture is obtained only in the single tube formed with an extruder. In this way, only a very small amount of pyrotechnic mixture is formed at any instant. | 12-18-2014 |
