Abstract: A copper jacketed explosive bullet for penetrating light armor, the bullet having a tubular hard heavy metal body filled with explosive and having an igniting mixture within the jacket forward of the explosive and a lightweight pyrophoric metal base plug for added burn time for increased fire starting ability.

Abstract: 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.

Abstract: A small caliber armor-piercing bullet is described in which a case hardened steel nosed lead projectile is utilized to help reduce projectile fragmentation at impact.

Abstract: An armor-penetrating projectile comprises an outer substantially cylindrically tubular member of great length/diameter ratio and density, centered on an axis, and having an axially throughgoing bore defined by an inner surface and an axially elongated inner member of greater strength and elasticity than the outer member extending axially through the bore the full length of the outer member and having an outer surface in tight radial contact with the inner surface of the outer member at at least a plurality of annular locations spaced along the axis. This inner member can be a bundle of wires that is inserted through the bore after the outer member has been expanded by heat, then twisted and longitudinally prestressed to lock tightly in the outer member.

Abstract: A frangible projectile comprising a plurality of interfitting, filled polymeric portions is provided with controlled properties.

Abstract: A supersonic nonspinning training projectile has a projectile body extending along an axis and having axially spaced front and rear ends and an aerodynamic rod projecting axially forwardly from the front end of the body. Thus when the projectile is fired axially forward the rod creates turbulence effective laterally on the projectile body at a wind-attack point which moves axially forward from a rear point to a front point as projectile speed drops. It is possible according to the invention to vary the mass distribution of the projectile and thereby displace the center of mass of the projectile axially between the front and rear points. Thus when the wind-attack point moves axially forward of the center of mass the flight of the projectile destabilizes. Such an arrangement works well even at supersonic speeds, so that the projectile can be set to only fly accurately through a relatively short range, as the principal factor determining range after elevation is projectile speed and shape.

Abstract: An industrial cartridge has a case that contains a propellant charge of at least two successively arranged propellant charge powders deflagrating at differing speeds. The powders are separated from each other by a gas-permeable cover extending transversely to the case axis. The case of the cartridge contains a compressible seal at the opposite end to the base end of the case. An ignition-transmitting tube is axially arranged in the case. The tube includes, at the level of the second and/or last propellant charge powder as seen from the base, a cover which is thinner than the wall of the ignition-transmitting tube.

Abstract: 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.

The first plug part is connected to the head and defines an open ended chamber which is closed off by the second plug part. The first part includes a tapering pin which projects downwardly through the chamber and engages in an opening in the second part so that on firing the bullet remains an integral unit.

Abstract: A projectile arrangement for a gun barrel weapon having a plurality of sub-caliber projectiles which are mounted on a common sabot which is composed of a plurality of segments. These projectiles are designed for a sequential flight one behind the other at predetermined distances and along a common flight path and are joined to each other by means of a wire. The leading projectile deactivates a detonating charge upon impacting on a target region of a "actively armored" target, so that the next following projectiles can become target-effective without being disturbed.

Abstract: A highly accurate projectile for use with small arms especially pistols and revolvers, having a cylindrically-shaped body portion and a nose formed adjacent thereto. The cylindrically-shaped body has a length which is equal to at least half the overall length of the projectile in order to position the center of gravity of the projectile within the body portion. The nose of the projectile is in the nominal shape of a truncated cone having sides which are rounded at the forward end thereof in order to meet a flat front surface. The flat front surface locates the center of pressure of the projectile well forward of the center of gravity of the projectile. The unique configuration and distribution of weight of the projectile allows for its highly accurate use with small arms.

Abstract: A shotgun slug having a frusto-conical body that increases a diameter from front to rear and which further includes a plurality of vanes projecting radially from the body which extend obliquely along the length thereof. The top lands of the vanes describe a truncated cone that is axially aligned with the body and which provide an interference fit with the bore of the gun barrel. The pitch of the cone described by the vanes is steeper than that of the supporting body so that the height of the vanes decrease from front to rear. Sufficient radial depth is given to the vanes so that the vanes retain their shape after the slug has been swagged in the barrel during firing. Accordingly, a stabilizing spin is imparted to the slug as it moves through the air towards the target. The slug is further provided with a nose heavy geometry which further enhances its flight characteristics thereby improving both range and accuracy.

Abstract: A non-ablative heat sensitive nose cap uses a highly conductive solid ford ogive and rear segmented ogive member, in contact with a low melting point locking ring which is thermally isolated from the main projectile body. The locking ring holds the rear ogive segments together until the desired time for projectile-break. Break-up occurs when a zinc alloy locking ring fails under the combined influence of decreasing yield strength and centrifugal force due to launch and free flight imposed spin.
