Abstract
A cartridge incorporating a projectile assembly, the projectile assembly having a base, mid body component housing a marking powder and metallic nose cap. The projectile's mid-body component houses liquids in a cylindrical compartment, where set-back and rotation induce chemical mixing, and in flight allowing for a chemical reaction, and at impact the projectile undergoes wall failure in the mid body, resulting from shear and residual rotational momentum, the actions in combination releasing and expelling marking materials, the ejection suspended signature producing materials, including liquid, powdered metals or fine particles released into the atmosphere emit and reflect light, the signature materials producing an observable signature at the projectile's impact location.
Claims14
A gun fired ammunition cartridge incorporating a spin stabilized projectile, said projectile comprising:
- (1) a metal ogive comprising a forward metal bore riding feature,
- (2) a mid-body frangible cylindrical assembly coupled to the forward metal bore riding feature at a forward end, the mid-body cylindrical assembly incorporating a cylindrical capsule configured to house a liquid marking payload comprising one or more chemical liquid materials, the liquid marking payload being aligned to the projectile's axis of rotation and proximate to the projectile's center of gravity;
- and
- (3) an aft metal base comprising a driving band,
- wherein the liquid marking payload is centered approximately equidistant between the forward bore riding feature and the driving band, and
- wherein the cartridge retains strength when compressed upon being loaded into a weapon, and upon firing, the projectile exhibits a ballistic flight stability over the trajectory of the projectile and, upon impact, the projectile breaks up and releases.
