摘要： Additive Manufacturing (AM) is used to make aids that target the training of K-9s to detect explosives. The process uses mixtures of explosives and matrices commonly used in AM. The explosives are formulated into a mixture with the matrix and printed using AM techniques and equipment. The explosive concentrations are kept less than 10% by wt. of the mixture to conform to requirements of shipping and handling.

摘要： A hybrid rocket solid fuel grain having a cylindrical shape and defining a center port is additive manufactured from a compound of thermoplastic fuel and passivated nanocomposite aluminum additive. The fuel grain comprises a stack of fused layers, each formed as a plurality of fused abutting concentric circular beaded structures of different radii arrayed defining a center port. During operation, an oxidizer is introduced along the center port, with combustion occurring along the exposed port wall. Each circular beaded structure possesses geometry that increases the surface area available for combustion. As each layer ablates the next abutting layer, exhibiting a similar geometry is revealed, undergoes a gas phase change, and ablates. This process repeats and persists until oxidizer flow is terminated or the fuel grain material is exhausted. To safety achieve this construction, a fused deposition additive manufacturing apparatus, modified to shield the nanocomposite material from the atmosphere is used.

摘要： An additively manufactured solid fuel grain for a hybrid rocket engine having a cylindrical shape, defining a center combustion port and comprising a stack of fused layers of polymeric material suitable for hybrid rocket fuel. Each layer is formed as a plurality of fused abutting concentric beads of solidified material arrayed around the center port. An oxidizer is introduced into the solid fuel grain through the center port, with combustion occurring along the exposed surface area of the solid fuel grain center port wall. Each concentric bead possesses a surface pattern that increases the combustion surface area and when stacked forms a rifling pattern of undulations that induces oxidizer-fuel gas axial flow to improve combustion efficiency. The port wall surface pattern persists during the rocket engine's operation as the fuel phase changes from solid to gas and is ablated.

摘要： A concealed amalgamated neutralizer covertly combines neutralizer material comprised of various combinations of inert materials such as calcium carbonate or silicates with common explosive material for the prevention of malicious use of the explosive material in improvised explosive devices. The concealed amalgamated neutralizer device may vary in shape, size, and color and is therefore adaptable to varying methods of containment typified by common pyrotechnic products. The neutralizer material mimics the explosive material of the pyrotechnic products without detection. Upon disassembly of a concealed amalgamated neutralizer device, the neutralizer material is mixed with and neutralizes the explosive material rendering the explosive material useless as a component for an improvised explosive device.

摘要： A heat generating structure includes a substrate, a coating and a polymeric material. The substrate comprises a first material. The coating comprises a second material, different from the first material that covers at least a portion of the substrate. The coating and substrate, upon being thermally energized to their minimum alloying temperature, react in a first exothermic reaction that is an alloying reaction. The relative quantities of the substrate and coating are such that the first exothermic reaction yields a first amount of exothermic energy that is insufficient to cause self-sustained propagation of the first exothermic reaction. The polymeric material covers substantially all of the substrate and coating, and is different from the first and second materials. The polymeric layer, upon being thermally energized, reacts with at least one of the substrate and coating in a second exothermic reaction. The second exothermic reaction yields a second amount of exothermic energy that, when combined with the first amount of exothermic energy, is sufficient to propagate the first exothermic reaction in a self-sustained manner.
