Abstract
A projectile to be, fired from a non-rifled tube includes an elongated foody and a stabilizer secured to the tail end of the forebody for enhancing the projectile flight stability and for imparting spin to the projectile. The stabilizer includes a threaded member that extends integrally into a forward section, a peripheral channel and a grooved aft section. The forward section has a generally smooth cylindrical shape. The peripheral channel extends along the entire peripheral contour of the stabilizer and has a generally semi-circular cross-section, for generating an expansion wave and for directing air flow toward the grooved aft section. The grooved aft section is cylindrically shaped relative to a longitudinal axis, and has a predetermined number of identical, equally spaced, circumferentially positioned grooves which traverse the entire axial length of the aft section, and which are angled relative to the longitudinal axis. Each angled groove is defined by two substantially parallel side walls.
