A non-energetic smoke fill composition including a resin, a curing agent, a metallic filler, and a non-metallic filler, wherein the smoke fill composition is configured to be inserted into any of an artillery shell, a mortar cartridge, a gun cartridge, and in general an ogive of a projectile, and wherein the smoke fill composition is configured to be disseminated by a fuze and a supplemental charge to produce a signal visible in both day or night conditions.

White smoke formulations comprising triazine-borate cage compounds or triazine-phosphate cage compounds obscurants and a sucrose-potassium chlorate pyrotechnic fuel-oxidizer system are disclosed.

A novel pyrotechnic composition comprising nanostructured crystalline boron phosphide and oxidizer such as potassium nitrate wherein the crystalline boron phosphide is synthesized by a self-propagating high-temperature reaction. The nanostructured crystalline boron phosphide and oxidizer pyrotechnic composition unexpectedly emits smoke and green flame upon ignition.

An obscurant-emitting composition may comprise an oxidizer comprising a cation comprising at least one of an alkali metal or an alkaline earth metal, and an anion comprising at least one of nitrate, chlorate, bromate, iodate, perchlorate, periodate, or chlorite; a fuel; and a hydrated salt composition, wherein the obscurant-emitting composition comprises between 0.001% and 8% by weight hydrated salt composition.

A wind direction indicator for hunters includes a smoke generator, a housing, an electrical power source, an air pump and a switch all arranged such that the indicator may be actuated by a hunter using a single hand. The smoke generator may be a cartomizer as an example.

An enhanced pyrotechnic composition including an obscurant, a fuel, an oxidizer, and a nonivamide-cyclic anhydride adduct.

A smoke producing method and device of the present disclosure produces a non-incendiary, organic-polymerization based, smoke-producing reaction. Some versions of the smoke are effective carriers for capsaicinoid compounds. The method of generating smoke comprises initiating a frontal polymerization reaction by heating a composition comprising a monomer compound that exothermically polymerizes upon initiation with an initiator compound and an initiator compound that initiates polymerization of the monomer compound present at a mass concentration that is at least five percent of the mass concentration of the monomer compound. The polymerization of the monomer compound is exothermic, and in one embodiment the concentration of initiator compound is at least five percent of the concentration of monomer compound. The smoke mainly comprises thermal decomposition products of the initiator compound.
