Non-pyrotechnic, low observable tracer

摘要

A low observable photoluminescent tracer projectile, for use with a small caliber weapon at night—which utilizes a base phosphor material of Ca, Sr and S, or a base phosphor material of Y2, O2, and S—with a combination of minor dopant ingredients; which base phosphor material is mixed with a clear binder to form a photoluminescent material which is applied to the rear end, or base, of a small arms projectile as a thin layer; to which thin layer is added a layer of small retro-reflectors—whereby, when this projectile is fired from the weapon, the photoluminescent mixture will be activated and will be observable, using night vision at an angle of 0 to about 20 degrees from the rear end of the projectile.

主权项

1. A low observable photoluminescent tracer projectile comprising:
A photoluminescent composition affixed to the rear end of the projectile wherein said photoluminescent composition comprises (a) at least one member selected from the group consisting of Ca and Sr, (b) and S to form a phosphor based material combination; (c) at least one minor dopant selected from the group consisting of Eu, Sm, Dy, Ce, Mn, Cu, Al, and Tm; and (d) a clear binder.
