Small caliber chemiluminescent munitions
View Patent ↗The present invention relates to the field of training military, law enforcement personnel, or the like, tasked with the accurate firing of small caliber munitions. A need exists for quantifying the ability of the trainees by detecting the accuracy with which they are able to strike their intended targets, especially in nighttime training situations. This invention relates to munitions which contain a chemical light producing system; particularly to small caliber munitions containing a chemiluminescent chemical light system; and most particularly to small caliber munitions having selectable, marking, tracing, or combined tracing/marking utility.
1. A chemiluminescent light emitting plastic training projectile comprising:
an outer casing adapted to permit the passage of light therethrough, said outer casing having a first end and a second end and a continuous sidewall therebetween, said sidewall having an inner surface and an outer surface;
first and second chemiluminescent reactants placed within said outer casing;
a sealing cap adapted to sealingly engage said outer casing adjacent said second end thereof; and
a barrier device adapted to be positioned within said outer casing to substantially segregate said first and second chemiluminescent reactants said barrier device is constructed and arranged to have an interference fit with said inner surface of said continuous sidewall, said interference fit within the range of about 0.015″-0.06″;
whereby sizing of said interference fit within said range enables said projectile to incorporate tracing, marking or combined tracing and marking functionality.
2. The chemiluminescent light emitting plastic training projectile in accordance with claim 1 wherein:
said outer casing is frangible;
whereby upon impact said projectile disperses a chemiluminescent composition.
3. The chemiluminescent light emitting plastic training projectile in accordance with claim 1 wherein:
said outer casing is non-frangible;
whereby upon impact a chemiluminescent composition is retained within said projectile.
4. The chemiluminescent light emitting plastic training projectile in accordance with claim 1 wherein:
said interference fit is within the range of about 0.015″-0.039″;
whereby some leakage occurs between said first and second chemiluminescent reactants subsequent to firing, thereby permitting chemiluminescent light generation in-flight which provides tracing functionality.
5. The chemiluminescent light emitting plastic training projectile in accordance with claim 4 wherein:
said outer casing is frangible;
whereby upon impact said projectile disperses a chemiluminescent composition.
6. The chemiluminescent light emitting plastic training projectile in accordance with claim 4 wherein:
said outer casing is non-frangible;
whereby upon impact a chemiluminescent composition is retained within said projectile.
7. The chemiluminescent light emitting plastic training projectile in accordance with claim 1 wherein: said interference fit is within the range of about 0.04″-0.06;
whereby leakage is prevented between said first and second chemiluminescent reactants thereby preventing in-flight chemiluminescent light generation prior to impact and a marking functionality subsequent thereto.
8. The chemiluminescent light emitting plastic training projectile in accordance with claim 7 wherein:
said outer casing is frangible;
whereby upon impact said projectile disperses a chemiluminescent composition.
9. The chemiluminescent light emitting plastic training projectile in accordance with claim 5 wherein:
said outer casing is non-frangible;
whereby upon impact a chemiluminescent composition is retained within said projectile.
