The present invention relates to modular explosive charge devices that may be transported and deployed readily, expediently, and effectively, and features of the device and methods of fabrication and preparation thereof.
Explosives are used in a large number of practical applications, including military use, law enforcement, mining, construction and related professions and industries where the objective is to direct concentrated energy from explosives at a target or substrate to compromise or break up the target or underlying substrate. Often in such situations, particularly crisis or emergency situations, it is imperative that the explosive charge can be transported, placed, deployed and actuated readily and effectively in a time-critical, responsive and adaptable manner. Additionally, such situations often change or escalate without warning, and the explosive charge may have to be relocated, reset, and redeployed at a moment's notice. Often, conventional assembly, placement, and deployment of explosive charges is difficult, time-consuming, dangerous, burdensome, and lack ease of transport and lack in adaptability to changing conditions or changing assessments.
On a more general use level, conventional explosive charges often are configured so that the assembled device is transported with the actual explosive on-board. Such configurations make transport hazardous and subject to the restrictions or impracticalities that are concomitant with transport via air, water or ground vehicular means, or particularly in situations where the explosive charges are carried on the persons of the explosives team.
As such, there is a long-felt and pronounced present need for explosive charge devices that are modular and designed for rapid and straightforward assembly and operation and can be loaded on-site and adapted and modified immediately in event of a rapidly-changing situation. The present invention offers devices and methods that are simpler, more reliable, more stable and better adaptable to different environments, including unstable and transient target environments that may include rapid modification of the condition or required force of the charge, and thus the present invention promotes facility of transport, greater precision, greater flexibility, and greater effectiveness, thereby providing greater control and better ease of use and deployment efficacy to the construction, mining, security, military or law enforcement personnel operating the instruments and methods of the invention.
The present structure and system of the invention provides for a modular rapid deployment explosive charge device that can be fully-constructed and configured for immediate use, or, alternatively, presented for ready assembly on-site by operating personnel. In most preferred embodiments, the modular rapid deployment explosive charge device is in one of four configurations: a blasting modular rapid deployment charge configuration, a blasting tamped modular rapid deployment charge configuration, a pushing modular rapid deployment charge configuration, or a pushing tamped modular rapid deployment charge configuration.
In select “blasting” embodiments of the invention, blasting refers to the intrinsic operational properties of high explosives to produce a detonation velocity and force which can shatter materials that the force encounters.
In select “pushing” embodiments, pushing refers to the transfer of the energy produced via detonation of high explosives into an inert, highly dense, non-explosive, non-flammable material which, in turn, is operably propelled into a target structure or object thereby directing the compromise of the target structure or object. In preferred embodiments, a suitable push material may comprise rubber or plastic materials. In particular preferred embodiments, the suitable push materials comprises conveyor belt rubber or polyethylene plastic materials.
In select “tamped” embodiments, tamping refers to the use of highly dense, non-explosive, non-flammable material which, in turn, when properly placed on the rear end of the explosive charge will serve to redirect the explosive energy back toward the direction of the target objective, as opposed to permitting the energy of the blast to escape into the ambient atmosphere, and serves to dampen the action of or risk of uncontrolled blast energy at collateral objects, operating personnel, or bystanders.
In preferred embodiments of the invention, the modular rapid deployment explosive charge device will comprise (stable) housing for the explosive charge, clear tubing for the specific housing of detonation cord segments, heatshrink polyolefin tubing for stabilizing and fixing the shape and structure of the charge device, and adhesive materials to fix and secure the charge device to a target structure or target location. In particular preferred embodiments of the invention, the housing material for the explosive charge device comprises medium-density fiberboard which incorporates the benefits of low cost, stability, and the capacity to maximize the rigidity of the device structure with low weight while simultaneously mitigating hazardous fragmentation secondary effects of the blast.
In preferred tamped embodiments of the invention, the modular rapid deployment explosive charge device will incorporate hydrogel materials as the tamping material. In a most preferred embodiment, the tamping material will comprise Global Assets FE112 HydroBreach gel.
In preferred embodiments of manufacture or assembly of the invention, the modular rapid deployment explosive charge device manufacture or assembly will comprise steps of: forming structural housing for the explosive charge, incorporation of clear tubing sections for the specific housing of detonation cord segments, incorporation and securing heatshrink polyolefin tubing to the (detonation cord) clear tubing sections for stabilizing and fixing the shape and structure of the charge device to the housing, and application of adhesive materials to fix and secure the charge device to a target structure or target location. In particular preferred embodiments of the manufacture and/or assembly of the invention, the housing material used for the explosive charge device comprises medium-density fiberboard, which incorporates the benefits of low cost, stability, and the capacity to maximize the rigidity of the device structure with low weight while simultaneously mitigating hazardous fragmentation secondary effects of the blast.
Furthermore, in a particular preferred embodiment, the device is optimally designed for handheld use and thus features a small and lighter body and emphasized ergonomic shape for ease of manual handling. In particular preferred such embodiments, the overall device is carefully balanced in shape and weight to facilitate single-handed ease of use and performance with the device. In other preferred embodiments of the invention, the device is sized and shaped for ease of transport and concealment within a rucksack or similar personal transport instrument.
