  • PROJECTILE WITH FIRE-SAFE INFRA-RED STRIKE POINT MARKING
    Publication number: 20170045346
    Abstract: A projectile (100, 100a, 100b, 100c) containing two chemiluminescent dye components (123, 125), a dye powder (126) and one or more capsules (170) containing a pyrophoric substance. Upon impact at a target, a nose cap (110) of the projectile (100, 100a, 100b, 100c) and the capsule(s) (170) become broken, thereby allowing the pyrophoric substance to oxidize and emit an infra-red signal to mark the strike point. Oxidation of the pyrophoric substance is controlled, to allow the projectile to be fire-safe.
