International Classification:

F42B 12/38
C06B 23/00
F42B 12/42
C06B 33/00

Abstract:

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.

Filed:

Aug 28, 2014

Appl. No.:

14/471677

Inventors:

- Columbus OH, US
John R. Leach - Hilliard OH, US

International Classification:

F42B 12/28

Abstract:

A series of small explosive charges are used to preferentially crack the casing of a warhead to provide for a controlled fragmentation of the warhead. During detonation of the warhead's explosive fill, the casing will break early in the process along predetermined lines resulting in very large fragments that are projected toward the ground and away from innocent civilians. A fragmentation control collar which contacts these charges can be fitted on the outside of existing warheads. An annular liner within the warhead aids in the controlled fragmentation.
