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.

Nose for an inertial projectile

A nose unit for a discarding sabot penetrator having a bolt in a bore of the pointed nose which is temporarily displaced on firing due to acceleration and against a restoring spring. This produces a circular edge and a break in the contour of the nose to define a limit surface between a zone of supersonic airflow and a zone of subsonic airflow, at least during the separation of the sabot segments. This facilitates the uniformed detachment of the segments.

Penetrator projectiles

A sabot consists of a plurality of segments which define an air pocket for detaching the segments from a fin-stabilized subcaliber penetrator projectile. The air pocket is defined by a rear support region of the sabot. A front support region of the sabot includes a plurality of webs between each adjacent pair of which an air-through-streaming passage is defined. At least the web portion of each segment is made of synthetic material and such web portion has a curved part defining a fracture zone.

Segmented sabot

A nose unit for a discarding sabot penetrator having a bolt in a bore of the pointed nose which is temporarily displaced on firing due to acceleration and against a restoring spring. This produces a circular edge and a break in the contour of the nose to define a limit surface between a zone or supersonic airflow and a zone of subsonic airflow, at least during the separation of the sabot segments. This facilitates the uniformed detachment of the segments.
