Abstract

A trajectory (range) control device which is designed to fit behind the f of a fin stabilized ballistic projectile for correcting range error. The trajectory (range) control device is a self-contained, add-on module, which will screw into the forward portion of the projectile. The fuze will then screw into the trajectory (range) control module, which has a small through hole that will coincide with the center of the fuze and the center of the projectile. This through hole is intended to provide a channel in which the fuze can detonate the intended booster charge which will in turn ignite the high explosive payload or function the payload of the fin stabilized ballistic projectile. The trajectory control device will not make changes to the existing projectile or fuze. During the course correction phase, eight spring loaded flare tabs will deploy from the device. The flare tabs create a blunt cross-sectional area in front of the projectile, thus creating more drag and effectively slowing the projectile.
