20100229750 | Combustible cartridge cased ammunition assembly - A combustible cartridge assembly is described. The assembly of one embodiment includes a projectile, a body having a first end portion coupled to the projectile and a second end portion opposite the first end portion. The body is made of a combustible material configured to be consumed upon firing the ammunition round assembly. A sleeve is at least partially contained within the base. The sleeve has a free end portion radially to adjacent to and coupled to the second end portion of the body. The sleeve and the body defines an interior area configured to contain a combustible propellant. A non-combustible base at least partially is coupled to the sleeve and is adjacent to the second end portion of the body. | 09-16-2010 |
20110192310 | AMMUNITION ASSEMBLY WITH ALTERNATE LOAD PATH - An ammunition round assembly with alternate load path is disclosed herein. The ammunition round assembly includes a projectile, a body engaging the projectile, and a non-combustible base at least partially enclosing the body. A structural member having first and second engagement portions opposite to each other is positioned inside an interior space defined by the body and the base. The first engagement portion firmly engages the base, and the second engagement portion firmly engages the projectile to provide an alternate load path between the projectile and the base. | 08-11-2011 |
20110308420 | INFRARED SIGNATURE POWDER AND METHODS OF CONTROLLING THE TEMPERATURE, DURATION, AND INTENSITY OF INFRARED SIGNATURE RADIATION - In accordance with aspects of the invention, an infrared signature powder (“IR powder”) suitable for marking targets and other objects is provided. The IR powder primarily includes porous, pyrophoric iron and moderators. The duration, temperature, and intensity of the emitted infrared radiation can be tailored during the powder's production process by adjusting the proportion or properties of the moderators in the IR powder. Additionally, a method of producing the IR powder is provided. The method can include the following general steps: heat a blend of aluminum and iron powders to cause an inter-metallic reaction; leach the aluminum from the iron; and mix a selected moderator and a binder with the iron in selected proportions to create the IR powder. Many of these steps are performed in an oxygen-free environment to prevent the iron from prematurely oxidizing. Similarly, the IR powder is encapsulated in an oxygen-free frangible ampoule or other container. | 12-22-2011 |
20120291652 | AMMUNITION ASSEMBLY WITH ALTERNATE LOAD PATH - An ammunition round assembly with alternate load path is disclosed herein. The ammunition round assembly includes a projectile, a body engaging the projectile, and a non-combustible base at least partially enclosing the body. A structural member having first and second engagement portions opposite to each other is positioned inside an interior space defined by the body and the base. The first engagement portion firmly engages the base, and the second engagement portion firmly engages the projectile to provide an alternate load path between the projectile and the base. | 11-22-2012 |
20120291653 | COMBUSTIBLE CARTRIDGE CASED AMMUNITION ASSEMBLY - A combustible cartridge assembly is described. The assembly of one embodiment includes a projectile, a body having a first end portion coupled to the projectile and a second end portion opposite the first end portion. The body is made of a combustible material configured to be consumed upon firing the ammunition round assembly. A sleeve is at least partially contained within the base. The sleeve has a free end portion radially to adjacent to and coupled to the second end portion of the body. The sleeve and the body defines an interior area configured to contain a combustible propellant. A non-combustible base at least partially is coupled to the sleeve and is adjacent to the second end portion of the body. | 11-22-2012 |
20120318161 | CONSUMABLE AMMUNITION ASSEMBLY HAVING A NITROGUANIDINE CASE AND METHOD OF MAKING A CONSUMABLE AMMUNITION ASSEMBLY HAVING A NITROGUANIDINE CASE - The present disclosure describes various embodiments of nitroguanidine-based consumable ammunition assemblies and methods of producing and using these assemblies. In one embodiment, for example, a nitroguanidine-based consumable ammunition assembly can include a projectile, a Combustible Cartridge Cased body using nitroguanidine as the primary energetic material, and a composite case base interfacing with the CCC body. | 12-20-2012 |
20130014667 | PROPELLANT GAS OPERATION/INITIATION OF A NON-PYROTECHNIC PROJECTILE TRACER - The present disclosure is directed to propellant gas initiation of a non-pyrotechnic projectile tracer. In some embodiments, cartridge-propellant gasses act upon a piston to break a frangible chemiluminescent liquid chemical ampoule to initiate a luminous reaction independently of and prior to any projectile motion. The piston may be a distinct piston, a separate component functioning as a piston, or the overall tracer container acting in the manner of a piston. Embodiments of the disclosure are applicable to direct-fire ammunition ranging from small arms through large caliber main battle tank ammunition. | 01-17-2013 |
20140196626 | PROPELLANT GAS OPERATION/INITIATION OF A NON-PYROTECHNIC PROJECTILE TRACER - The present disclosure is directed to propellant gas initiation of a non-pyrotechnic projectile tracer.

20150083012 | REAR EJECTION IMPACT MARKING AMMUNITION ASSEMBLY - An ammunition assembly comprising a body having an interior chamber between leading and trailing ends, and a nose portion is attached to the leading end. An ejectable payload is disposed in the chamber. An ejectable payload is disposed in the marking chamber. A pusher, adjacent to the nose and interior chamber, is axially moveable into the interior chamber to push the payload rearwardly out of the body's trailing end. An aft cover is connected to the trailing end and retains the payload in the body until the nose impacts a target. The aft cover is separable from the body when the pusher ejects the payload out the trailing end portion when the nose impacts the target so the ejected payload marks the target without being obscured by the body or the target after impact. | 03-26-2015 |
