摘要： The present invention is a pyrotechnic time delay system that is improved over prior-art designs. Specifically, the system described herein comprises at least one delay element. The delay element or delay elements each have an input charge, a delay composition, and an output charge. Both the input charge and the output charge are igniter compositions and are comprised of the same components despite having different functional goals. The input charge and output charge compositions preferably contain titanium, manganese dioxide, and polytetrafluoroethylene. The delay composition may be modified from current formulations to include manganese and manganese dioxide, or tungsten and manganese dioxide. The system disclosed herein may be comprised of one delay element, or it may be modular wherein multiple delay elements are connected in series.

摘要： A fast utility access device (FUAD) is provided that includes one or more casings, each of the one or more casings collectively defining a bore, and a core of a highly exothermic composition contained in the bore and surrounded by a thermally insulating inner liner, the highly exothermic composition ignitable to create a post-ignition temperature of between 500° C. and 4000° C. A method is also provided for breaching a target and includes contacting the inventive access device with a breaching target substrate, thermally coupling at least one reaction initiator to the highly exothermic composition, triggering the at least one reaction initiator thereby igniting the highly exothermic composition, and allowing the highly exothermic composition to achieve a post-ignition temperature sufficient to melt the breaching target substrate, forming a hole therethrough.

摘要： An energetic material composite comprising fuel particles and a hydrated compound is disclosed. The energetic material composite is formed by dispersing fuel particles, which have a negative standard reduction potential relative to a standard hydrogen electrode, in a solvent containing dissolved hydrate, followed by a removal of solvent. When initiated, the fuel particles react with the water bound in the hydrated compound to release energy and hydrogen gas.

摘要： A self-glowing solid material comprises a man-made metal mixture containing at least one rare earth metal and an oxide of iron. The material is inducible by flame initiation to self-glow with yellow-to-red colors (577-to-700 nanometer wavelengths). A stealth tracer ammunition comprises a projectile body having a tip and a base, and a solid pellet disposed in the base. The pellet may be made from the above-mentioned self-glowing solid material or another suitable material. The pellet becomes incandescent as a result of being heated when the ammunition is fired. The incandescent pellet emits a glow observable only from behind when the ammunition travels downrange after being fired. An illuminant comprises a bimodal blend of a man-made metal mixture containing at least one rare earth metal and an oxide of iron. The bimodal blend is a blend of smaller-sized fragments and larger-sized pellets. The illuminant is capable of ignition and dispersion in response to ballistic energy to create illumination. An illumination device comprises a body having an interior cavity, the body configured to be launched as a projectile or configured to contain projectiles. An illuminant is disposed in the cavity, the illuminant comprising a bimodal blend of a suitable illuminant material. The illuminant is capable of ignition and dispersion in response to ballistic energy to create illumination.

摘要： Embodiments of the present invention are directed to various devices, systems and methods of providing a restartable, hybrid-rocket system that uses Acrylonitrile Butadiene Styrene (ABS) and compressed air containing oxygen levels up to 40% as a propellant. Alternatively, embodiments of the present invention includes restartable hybrid rocket system that uses a heterogeneous matrix of ABS and a solid oxidizing agent in addition to compressed air as a propellant. When the ABS is exposed to an electrical potential field, the electrical field's effect on the ABS produces localized arcing between multiple layers of the ABS resulting in joule heating and pyrolysis of the ABS. The pyrolysis produces spontaneous combustion of the ABS once the oxidizer flow provides a local oxygen partial pressure greater than two atmospheres at the surface of the ABS.

摘要： A non-destructive examination (NDE) system for use on a structural element comprises nano-energetic actuators configured for creating a controlled combustion in response to thermal energy, thereby inducing vibrations in a surface of the structural element. The NDE system further comprises sensors configured for measuring the vibrations induced in the surface of the structural element and generating vibration data. An applique comprises a planar substrate, nano-energetic actuators affixed to the planar substrate, each configured for creating controlled combustions in response to thermal energy, and an adhesive affixed to the planar substrate, such that the applique can be adhered to a structural element. A means of transportation having an accumulation of ice comprises a structural element, and nano-energetic actuators, each configured for creating a controlled combustion in response to thermal energy, thereby inducing vibrations in a surface of the structural element great enough to generate cracks in the ice.

摘要： An energetic nanocomposite includes fuel nanoparticles and oxidizer nanoparticles covalently bonded to negatively charged functionalized graphene sheets. A preferred example includes Al fuel nanoparticles and Bi2O3 nanoparticles. A preferred method of formation mixes a solution of positively charged fuel nanoparticles, positively charged oxidizer nanoparticles, and negatively charged functionalized graphene sheets having functional groups to bond with the positively charged fuel nanoparticles and positively charged oxidizer nanoparticles. Self-assembly of the energetic nanocomposite is permitted over a predetermined time via the attraction and aggregation of the positively charged fuel nanoparticles positively charged oxidizer nanoparticles and negatively charged functionalized graphene sheets. Additional methods and nanocomposites include unfunctionalized graphene sheets, which can be commercial grade sheets.
