ABSTRACT:
An intelligent projectile that can be detonated at a predetermined range via a wide angle infrared laser. The projectile is fitted with a detector that is sensitive to the frequency of a wide angle laser beam that is attached to the weapon. Using the range obtained by the range finder, the wide angle laser beam is fired when the projectile is in proper position relative to the target. To prevent the projectile from exploding prior to its being fired, a series of batteries is held in a track via compressions springs. The springs must be compressed via centrifugal force due to the projectile spinning as a resulting of rifling in the weapon. Once, sufficient centrifugal force is reached, the batteries will slide into a "contact" position so that the projectile can be detonated. The apparatus fits within standard 40 mm shell casings and can be fired by conventional grenade launching weapons.
