Abstract

An improved nose construction for a subcaliber inertial projectile which is ired with the aid of a sabot. A hood or body is mounted on the nose portion of the projectile. The hood is made of synthetic material and includes longitudinally extending fracture zones and is of substantially cylindrical shape. The frontal portion of the hood is recessed and forms an air flow receiving surface. In lieu of a hood a body, made of a thermoplastic material or the like, may be mounted on the nose portion. This body is adapted to disintegrate as result of air friction. The presence of the hood or body on the nose portion of the projectile, as it exits from a non-illustrated gun barrel, avoids or at least reduces unfavorable air-streaming forces which destabilize the flight characteristics of the projectile and thereby favors a uniform separation of the sabot segments from the projectile. Such uniform separation reduces or completely eliminates undesirable oscillations during flight of the projectile. After the hood or body have disintegrated the projectile acquires a more favorable c.sub.w value (drag coefficient during flight.
