摘要:
The armor tile system embodying the principles of the present invention comprises one or more hybrid tiles which can be connected together to cover a protected structure. Various arrays of material layers may be utilized (1×1, 2×2, 4×4, 2×8, etc) within a hybrid tile system and multiple hybrid tiles may be mounted on the area to be protected. Each hybrid tile comprises one or more material layers stacked within a single metal matrix casting. Each material layer within a hybrid tile includes at least one reinforcement insert arranged along a common surface. The reinforcement inserts comprise material types suitable for containment, structural support, and projectile deflection and destruction. The armor tile system of the present invention is created utilizing a molten metal infiltration process. In the preferred embodiment, the reinforcement inserts are arranged along a common surface within each material layer and further positioned within the mold cavity to create a controlled inner seam between adjacent reinforcement inserts to keep the reinforcement inserts from shifting during metal infiltration. The outer periphery of the material layer(s) and the mold cavity inside periphery has a space defining an outer seam. Both the outer and inner seams may further contain a reinforcement material to enhance the effectiveness of the armor system if desired. The mold cavity is infiltrated with liquid metal which solidifies within the materials open porosity thereby binding the layers together to create a coherent integral structure.

A lightweight armor system may comprise multiple reinforcement materials layered within a single metal matrix casting. These reinforcement materials may comprise ceramics, metals, or other composites with microstructures that may be porous, dense, fibrous or particulate. Various geometries of flat plates, and combinations of reinforcement materials may be utilized. These reinforcement materials are infiltrated with liquid metal, the liquid metal solidifies within the material layers of open porosity forming a dense hermetic metal matrix composite armor in the desired product shape geometry. The metal infiltration process allows for metal to penetrate throughout the overall structure extending from one layer to the next, thereby binding the layers together and integrating the structure.

System and method for generating and storing electricity by electromagnetic induction using a magnetic field modulated by the formation, dissipation, and movement of vortices produced by a vortex material such as a type II superconductor and further including a vortex flux generator in cryostat and a refrigerant compartment having bi-directionally thermal transfer to the vortex flux generator. Magnetic field modulation occurs at the microscopic level, facilitating the production of high frequency electric power. Generator inductors are manufactured using microelectronic fabrication, in at least one dimension corresponding to the spacing of vortices. The vortex material fabrication method establishes the alignment of vortices and generator coils, permitting the electromagnetic induction of energy from many vortices into many coils simultaneously as a cumulative output of electricity. A thermoelectric cycle is used to convert heat energy into electricity.

Various implementations of the invention correspond to an improved vortex flux generator. In some implementations of the invention, the improved vortex flux generator includes a magnetic circuit configured to produce a magnetic field; a quench controller configured to provide a variable current; a vortex material configured to form and subsequently dissipate a vortex in response to the variable current, wherein upon formation of the vortex, a magnetic field density surrounding the vortex is urged to decrease, and wherein upon subsequent dissipation of the vortex, the urging to decrease ceases and the magnetic field density increases prior to a reformation of the vortex, and wherein the decrease of the magnetic field density and the increase of the magnetic field density correspond to a modulation of the magnetic field; an inductor disposed in a vicinity of the vortex such that the modulation of the magnetic field induces an electrical current in the inductor; and a dissipation superconductor electrically disposed in parallel with the vortex material and configured to carry, without quenching, an entirety of the variable current during dissipation of the vortex in the vortex material.

A Method of Producing a hybrid tile metal matrix composite armor is disclosed. First, dense ceramic plates are placed within the mold cavity and may rest on spacer(s) that separate the bottom surface of the ceramic plates from the base of the mold cavity to create a space therebetween. The plates are further positioned within the mold cavity to create a controlled space between any adjacent plates. A second set of spacers may be placed on the plates top surface to create a space between the mold cavity cover and the ceramic plates top surface. A plurality of ceramic plates and spacers may also be stacked into multiple layers according to the shape of the mold cavity and desired ballistic resistance. The mold cavity is next infiltrated with liquid metal under pressure forming a hybrid metal matrix composite structure with an encapsulating aluminum rich skin.
