ABSTRACT:
A projectile includes a mechanism which allows the fin position to be reved after the projectile leaves the launch tube thus allowing the fins to have reversed leading edges, which avoids the costly weight of the one-piece design in the prior art, which is a parasitic weight that will result in a lower velocity, and consequently lower kinetic energy, from the same propellant charge. This mechanism also avoids having extra pieces falling from the muzzle and near the firing team or troops near the gun, and has the advantage of a simple, low-weight deployment mechanism which results in the least aerodynamic resistance after full deployment. The mechanism has at least one small winglet on each reversible fin which generates an aerodynamic lifting force to provide reversal of the fin after the projectile leaves the launch tube. These winglets are positioned and designed to cause the least increase in aerodynamic drag.
