ABSTRACT:
An aerodynamic device, such as a projectile includes an elongated forebody, and an aft section secured to the forebody. The aft section acts as a d control device, and includes a connecting member that extends integrally in a conically shaped flared section, for generating a lift force to help stabilize the projectile during forward flight. The aft section further includes a flange that extends from the flared section, and that provides velocity decay and optimal drag, in order to limit the projectile flight and descent within a predetermined safety or emergency range. The flared section is defined between an innermost edge positioned adjacent to the connecting member, and an outermost edge positioned adjacent to the flange. The flange includes a forward facing wall that extends from the outermost edge and that has a height "H" that controls the amount of drag on the projectile, such that the outer diameter of the aft section is less than, or equal to the inner diameter of the gun barrel from which the projectile is fired.
