Non-pyrotechnic signature for medium caliber projectile

Abstract

A visible or invisible light-producing device in an inert target practice projectile creates visible and/or infrared light initiated by a deceleration sensitive triggering element when the projectile impacts a target. A visible signature is creating for recording the impact to provide training without the use of any pyrotechinc, or other hazardous materials being deposited on the impact area. The light producing device may be initiated by fuze electronics—prior to actual impact—to facilitate simulating an airburst projectile for training or testing purposes.

1 . A target practice projectile consisting of:
 a cylindrical body having a nose at the front end thereof and a base at the rear end thereof, the body containing an electrically actuated device that produces a non-pyrotechnic flash in response to impact of the projectile upon said target.   
     
     
         2 . The projectile of  claim 1 , in which the electrically actuated device is a light emitting diode. 
     
     
         3 . The projectile of  claim 1 , further comprising:
 a piezoelectric element that deforms in response to impact of the projectile and produces an electrical signal that electrically actuates the non-pyrotechnic flash producing device.   
     
     
         4 . The projectile of  claim 2 , further comprising a battery in series with the light emitting diode and an electrical switch that closes upon impact of the projectile and electrically actuates the light emitting diode. 
     
     
         5 . (canceled) 
     
     
         6 . The projectile of  claim 1 , further comprising
 one or more lenses for directing the non-pyrotechnic flash.   
     
     
         7 .- 8 . (canceled) 
     
     
         9 . The projectile of  claim 1  wherein said non-pyrotechnic flash comprises visible, infrared or ultraviolet light. 
     
     
         10 . (canceled)
