Fluidic range-safe device

摘要

A disintegrable projectile is disclosed which utilizes thermal energy obtained from the conversion of the kinetic energy of the air moving past the projectile to cause its fragmentation. The projectile employs an air intake nozzle axially disposed in the nose portion of the projectile and a resonance tube located in the body portion of the projectile in thermal contact therewith. The resonance tube develops the thermal energy which is transmitted to the body portion to cause the fragmentation thereof. The projectile of the present invention is intended for use in gunnery training and practice conducted within limited size training and practice ranges, where civilian personnel and property may be in proximate location.
