Abstract
A propellant composition comprises a propellant solvent, a propellant base, and a plurality of metal nanoparticles. A powder or dried propellant composition is formed by removing at least a portion of the propellant solvent. The metal nanoparticles of the plurality of metal nanoparticles are nonionic. The plurality of metal nanoparticles functions to reduce visible light output by the propellant composition during deflagration.
Claims20
A propellant composition, comprising:
- a propellant solvent;
- a propellant base;
- and
- a plurality of metal nanoparticles, the metal nanoparticles of the plurality of metal nanoparticles being nonionic, wherein the plurality of metal nanoparticles functions to reduce visible light output by the propellant composition during deflagration.
The dry or powdered propellant composition manufactured by a process comprising:
- providing the propellant composition of claim;
- and
- removing of at least a portion of the propellant solvent.
An ammunition cartridge, comprising:
- a projectile;
- and
- a dry or powdered propellant composition, the propellant composition comprising:
- a propellant base;
- and
- a plurality of metal nanoparticles dispersed into the propellant base, the metal nanoparticles of the plurality of metal nanoparticles being nonionic, wherein the plurality of metal nanoparticles functions to reduce visible light output by the propellant composition during deflagration.
The ammunition cartridge of claim 0, further comprising:
- a casing, wherein the projectile is coupled to the casing, the casing and the projectile defining an interior cavity, and wherein the propellant composition resides within the interior cavity;
- and
- a priming composition arranged proximate to the propellant composition, the priming composition being configured to ignite the propellant composition in response to a triggering condition.
A method of deflagrating a propellant composition in a manner that reduces visible light output by the propellant composition during deflagration, the method comprising:
- providing a propellant composition comprised of:
- a propellant base;
- and
- a plurality of metal nanoparticles, the metal nanoparticles of the plurality of metal nanoparticles being nonionic, wherein the plurality of metal nanoparticles functions to reduce visible light output by the propellant composition during deflagration;
- and
- causing a triggering condition that ignites the propellant composition and causes deflagration thereof, the metal nanoparticles of the propellant composition reducing visible light output by the propellant composition during deflagration.
