Proposed is an emulsion explosive composition containing 80% to 95% by weight of an oxidizing agent aqueous solution containing hydrogen peroxide, nitrate, and diethylene triamine penta(methylene phosphonic acid) (DTPMPA), 0.1% to 10% by weight of an emulsifier, and 2% to 15% by weight of an oil. The emulsion explosive composition can effectively solve self-gassing problems caused by a reaction between hydrogen peroxide and nitrate.

An electrically operated propellant includes a perchlorate oxidizer and a water insoluble polymeric binder with a water solubility of less than 0.1 grams (g) per 100 grams water at 25° Celsius (° C.). The electrically operated propellant is substantially waterless with a water content of less than 10 weight % (wt. %) water based on total weight of the electrically operated propellant.

A high density, generally recognized as safe hybrid rocket motor is described which has a density-specific impulse similar to a solid rocket motor, with good performance approaching or equal to a liquid rocket motor. These high density hybrid motors resolve the packaging efficiency/effectiveness problems limiting the application of safe, low cost hybrid motor technology.

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 dements 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.

A nitrocellulose-based composition for use as a propellant or as a combustible item is provided. The nitrocellulose-based composition includes a nitrate ester-based component including nitrocellulose; and a stabiliser (I) in the form of a long aliphatic chain having at least two unsaturation sites, the compound having a molecular weight of at least (120) and an iodine number of at least (25).

An explosive composition for use in telescopically expanding non-lethal training ammunition comprises tetrazene and paraffin wax. The explosive composition can be used as a primer and/or as a source of energetic material in a telescopically expanding non-lethal training cartridge; it can be used to propel a projectile from a telescopically expanding non-lethal training cartridge; and/or it can be used to expand telescopically a non-lethal training cartridge within a host gun.

An explosive sheet simulant that uses an ethylene vinyl acetate polymer combined with a mixture of a boron carbide and iron oxide for X-ray attenuating properties, and components of the mixture selected for predetermined flexural modulus combined with particle density, effective atomic number, X-ray transmission properties, or millimeter wave properties.

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.
