<p>The present disclosure is directed to propellant gas initiation of a non- pyrotechnic projectile tracer. In some embodiments, cartridge-propellant gasses act upon a piston to break a frangible chemiluminescent liquid chemical ampoule to initiate a luminous reaction independently of and prior to any projectile motion. The piston may be a distinct piston, a separate component functioning as a piston, or the overall tracer container acting in the manner of a piston. Embodiments of the disclosure are applicable to direct-fire ammunition ranging from small arms through large caliber main battle tank ammunition.</p> |
