There is disclosed a limited range, high-speed projectile with a flat trajectory. The range is limited by controlling the air resistance of the projectile, so that the air resistance increases markedly when the projectile speed drops below a certain value.

Limited-range projectile having a flat trajectory

A projectile fired from a gun barrel, aimed in straight flight upon a small arget, has a massive armor-piercing body spacedly surrounded by a sleeve which defines with its outer surface a ring channel that may also serve as a combustion chamber for generating additional thrust. The sleeve, whose cylindrical outer periphery provides guidance in the gun barrel, is axially divided into a rear portion rigid with the massive body and a relatively slidable front portion. In an initial forward position of this front portion, an annular shutter mounted on its inner surface obstructs the ring channel by engaging an annular shoulder on the body, the sleeve then effectively acting as a sabot which blocks the escape of combustion gases from the gun blast. Upon leaving the gun barrel, the slidable front portion is forced back by the pressure of ambient air and unblocks the ring channel while simultaneously venting that channel to the surrounding atmosphere through slots provided in this portion forwardly of its valve ring.
