  • Patent number: 8250987
    Abstract: A Kinetic Energy penetrator round is shown effective in neutralizing incoming air borne threat munitions such as rockets, artillery, or mortars for instance, without posing a threat in urban environments to harm bystanders on the ground. There are also no hazards or expense with this round of cleaning up unexploded ordnance, which might have occurred with other types of rounds due to unreliability of self destruct mechanisms. Shown herein is a kinetic energy penetrator for air defense that merely self destructs beyond its operational range into fragments that are not lethal to personnel on ground; no pyrotechnic or energetic materials means are used to activate this self destruct process. A full bore projectile structure is shown that is composed of plural axi-symmetric circular disks stacked on each other and tied by a shape memory metal wire of Nitinol. While operational as a joined group, the disks are a formidable round to kill an incoming air target.

  • Patent number: 8115149
    Abstract: A Hybrid Projectile is provided for delivering an explosive payload to a target wherein the Hybrid Projectile may be steered in flight using relatively inexpensive means. The Hybrid Projectile is exteriorly configured in the same physical exterior configuration of conventional ammunition of various standard types so it can be launched in conventional manner from the same weapon systems. However, internal features allow the Hybrid Projectile to be transformed in flight from a command signal to deploy wings and fins, and in some projectiles to telescope open to deploy such wings and fins. An inexpensive televisual means is activated in the fore region of the round which through RF uplink command can be used to select a path, while motors on the wings can then be used to more precisely glide the projectile to a target, or otherwise to abort the target run.

  • Patent number: 6931993
    Abstract: Small, medium and large caliber ammunition housing multiple projectiles are traced by means of a tracing/marking system utilizing chemlucent chemicals. The tracing/marking system also provides target marking when using small, medium and large caliber ammunition. Multiple projectiles are coated in a chemlucent chemical (referenced as the coating) and placed in the ammunition. Additionally, a liquid chemlucent chemical in a separate container is placed in the ammunition. When launched or fired from a gun or munition, the separate container breaks and the coating and the chemlucent chemicals combine, emitting light. The present system applies to multiple projectiles that are either launched in a scatter pattern from a gun or dispersed in a scatter pattern after the housing of the ammunition opens up outside the gun after firing. For military ammunition, the tracing/marking system may use buckshot, steel balls, or tungsten balls.

  • Patent number: 6575097
    Abstract: 13A case telescoped ammunition cartridge includes: a cylindrical cartridge case, a projectile disposed within the casing and a sleeve surrounding a portion of the forward end of the projectile. An obturator is disposed between the aft end of the sleeve and part of forward end of the projectile. A cup-shaped aft end seal is affixed to the case at the aft end thereof so as to be relatively movable with respect thereto during firing of the cartridge. The seal includes an external lateral surface adapted to engage an inner wall surface of a gun chamber. A cup-shaped forward end seal is affixed to the case at the forward end thereof so as to be relatively movable with respect thereto during firing of the cartridge. The forward end seal includes an external lateral surface adapted to engage the inner wall surface of the gun chamber and an external end surface adapted to abut a forward end surface of the gun chamber.

  • Patent number: 6497181
    Abstract: A flameless tracer and marker for small munitions and canon caliber projectiles incudes non-toxic, environmentally friendly chemiluminescent materials which are maintained in separate compartments is described. The munitions when fired glow intensely for several minutes and mark a target area upon impact.
