TRAINING AMMUNITION CARTRIDGE WITH A GASEOUS PLUME SIGNATURE

摘要

A training ammunition projectile has a solid chemical component disposed in a base compartment that produces a gaseous visible plume after impact. The ammunition cartridge generates kinetic energy while propelling the projectile through a weapon barrel. This firing process imparts heat into a projectiles driving band. When the projectile is in flight, heat passes from the projectile's driving band into a compartment in the projectile housing the chemical component. When the component is exposed to increasing heat and low pressure, the it undergoes rapid sublimation. The projectile is configured with a vent opening in its base for emergence of the gaseous plume during flight. The opening is preferably capped to allow for stable storage and to prevent any gas from escaping until the projectile is fired.

主权项

1. A training ammunition cartridge comprising a hollow projectile and a cartridge case with a propellant charge, the projectile having a hollow projectile body and a projectile head designed to withstand the forces applied when the projectile is fired from a gun and designed to burst when the projectile strikes a target, said projectile body having a projectile base with a compartment therein and further comprising:
a solid first chemical component disposed in the base compartment of the projectile which sublimates and forms a gas when heated to an elevated temperature during firing and flight of the projectile, said projectile body having an opening in said base for emergence of the gas for marking the trail of the projectile by means of a gaseous visible plume during flight.
