Abstract: A projectile enables axial assembly and precise angular alignment of cylindrical or ogival sections of the projectile without interfering with internal parts spanning those sections. The projectile includes a turnbuckle design that minimizes Outer Mold Line (OML) transitions and maintains structural integrity. Advantageously, the turnbuckle allows surface mounted antennas and internal electronics to span structural sections of the projectile. The minimal OML produces less turbulence and drag. Finally, the turnbuckle is structurally robust for gun launched applications.

Abstract: A projectile package loaded in a firearm includes a projectile having a rod attached to its rear region. The rod is attached to a drag member or vanes having elastic properties. When fired, the projectile is expelled from the barrel of the firearm. Upon exiting the barrel and until the projectile reaches its effective range, reactionary air forces caused by the projectile traveling through the air result in the elastic vanes orienting themselves in a tight formation behind the rear region of the projectile. As a result, the vanes do not detrimentally affect the aerodynamics of the projectile's flight within the effective range of the projectile. However, once the effective range of the projectile has been exceeded, the slower velocity of the projectile causes the elastic vanes to laterally fan or spread out so as to impede the forward progress of the projectile.
