Limited range projectile

摘要

A limited range projectile includes pyrotechnic material and reactive material. The pyrotechnic material is ignited at projectile launch. The pyrotechnic material ignites the reactive material. If the projectile reaches a maximum desired range prior to impact with a target, the ignited reactive material transforms the projectile into an aerodynamically unstable object.

1. A projectile, comprising:
an ogive portion including a solid penetrator that defines a forward end of the projectile and, abutting a rear of the solid penetrator and discrete from the solid penetrator, an ogive shell that defines a hollow interior; a cylindrical portion that abuts a rear of the ogive portion and is discrete from the ogive portion, the cylindrical portion including a shell and a hollow interior; a base portion that abuts a rear of the cylindrical portion and is discrete from the cylindrical portion, the base portion including a shell and a hollow interior; pyrotechnic initiating material disposed in the hollow interior of the base portion and extending from a rear end of the projectile forward into the hollow interior of the cylindrical portion; reactive material disposed in each of the hollow interiors of the base portion, the cylindrical portion and the ogive portion, the reactive material completely surrounding at least a portion of the pyrotechnic initiating material and extending from the rear end of the projectile past a forward-most extent of the pyrotechnic initiating material, an entire radially outermost surface of the reactive material being contiguous with respective inner surfaces of the base portion shell, the cylindrical portion shell and the ogive portion shell, a forward end of the reactive material abutting the rear of the penetrator.
