The invention relates to a combustible propellant charge case for ammunition dischargeable from a gun barrel, comprising cellulose, nitrocellulose, MO3 particles, wherein M = Mo and / or W, and cationic surfactant, wherein the average particle size d50 of the MO3 particles is 0.5–2.0 µm, the maximum particle size d100 of the MO3 particles is ≤ 20 µm, and the quotient of the average MO3 concentration in wt.% in a volume element of approximately 0.05 to 1.0 cm3 (cVE) at any desired point in the propellant charge case and the total MO3 concentration in wt.% (ctot) in the propellant charge case is cVE:ctot = 0.80–0 1.20.

In an ignition unit for a propellant charge (8), comprising an elongated ignition transfer charge (2) made of propellant powder, through which a free ignition channel (5) runs in its longitudinal direction, and a combustible support tube (3) that surrounds the ignition transfer charge (2) perpendicular to the free ignition channel (5), the ignition transfer charge (2) is formed from a first material which has a glass transition point below -40°C in an observed temperature range of -51°C to +71°C, and the support tube (3) is formed from a second material which does not have a glass transition point below +72°C.

This invention belongs to the field of solid propellant ignition technology, specifically relating to a conductive ignition paint, its preparation method, and its application. The invention involves mixing carbon nanotubes and high-energy fuel using a microfluidic device to form a suspension, followed by a microwave-assisted complexation reaction with a metal complexing agent. This allows the carbon nanotubes and high-energy fuel to form a stable core-shell structure through metal ion bridging, synthesizing a carbon nanotube composite coated with fuel. This composite is then mixed with a nanofiber dispersion, forming a hierarchical porous gel system with a three-dimensional interpenetrating network. Finally, a nano-oxidant is added and ultrasonically dispersed uniformly within the cavities of the network structure. The conductive ignition paint is then obtained through a rotary evaporation process. This invention's conductive ignition paint possesses a unique three-dimensional interpenetrating network structure and hierarchical porous characteristics, maintaining high energy density while reducing sensitivity, ensuring stable energy transfer and controllable release, and significantly improving the reliability and safety of ignition.

A combustible propellant charge sleeve for ammunition which can be fired from an armor barrel includes pulp, nitrocellulose, MO3 particles, wherein M=Mo and / or W, and cationic surfactant, wherein the average particle size d50 of the MO3 particles is 0.5-2.0 μm, the maximum particle size d100 of the MO3 particles is ≤20 μm, and the quotient of the average MO3 concentration in % by weight in a volume element of about 0.05 to 1.0 cm3 (CVE) at any point in the propellant charge sleeve and the total MO3 concentration in % by weight (Ctotal) in the propellant charge sleeve is CVE:Ctotal =0.80-1.20.

Disclosed is an ignition formulation for use as an aerial ignition incendiary. The ignition formulation comprises an incendiary material and an ignition fluid. The ignition fluid includes an alcohol-based reactant capable of reacting exothermically with the incendiary material to an extent sufficient to generate a flame. The ignition fluid also includes an alcohol-based suppressant capable of delaying a time needed to generate the flame upon contact of the alcohol-based reactant with the incendiary material compared to a time required to generate the flame in an absence of the alcohol-based suppressant.

The present disclosure is directed to an ignition device including a housing, a bulk fuel, and at least two lead wires as electrodes. The bulk fuel is made of a plastic material, such as polylactic acid (PLA) or epoxy resin. The bulk fuel contains an internally dispersed powdery conductive material, thereby obtaining a conductive solid fuel. One end of the lead wire is partially embedded in the bulk fuel. The other end of the lead wire is connected to a power source. A portion of the bulk fuel is gasified by energizing the lead wire, and the gasified fuel is combusted by reaction with an oxidant.

An eco-friendly fire starter system is disclosed, including a first container and a second container, the second container being configured to be removably stored within an interior of the first container. At least two combustible materials are used to catalyze a chemical reaction to combust the first container and the second container. One or more edible materials are stored within one of the first container or the second container.
