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.

Abstract: Methods of making cross sectional, functionally-graded munitions propellants exhibiting various distributions of particle concentrations and burn rate, including having a fast burning core and slower burning outer layer(s). Unlike prior art methods of preparing such munitions, propellants prepared according to our inventive method(s) may be performed substantially as a single extrusion step or as a few processing steps, without requiring the time, expense and/or difficulties that characterized familiar, laminating methods and methods which use multiple extruders. Our inventive method advantageously employs a demixing phenomenon that, prior to our inventive application and teaching, has been considered quite undesirable in the preparation of propellants where uniformity and well-mixedness have been propellant attributes widely sought after.

Abstract: Described are flameless tracer munitions that are expelled from land mines or in hand thrown devices, which are used to mark an enemy person, vehicle body, or tires on the vehicle, with materials that emit infrared (IR) light, or heat emitting materials, or with a visible ink or a dye. The subjects are then identified and pursued because of the ink or seen with infrared reading or heat seeking devices. The devices are both long duration (several hours) and also have high light intensity tracing and marking. These munitions are non-impact and non-lethal; are non-toxic, and biodegradable.

Abstract: A flameless tracer/marker provides heat mark chemicals with optional chemlucents chemicals that can be carried and delivered by a projectile to mark a target. This marking payload may be carried by small, medium and large caliber projectiles that are part of ammunition items including 20 and 40 mm grenade launched, 90 mm, 105 and 120 mm tank, 60, 81 and 120 mm mortar and 105 and 155 artillery ammunition. This ammunition is gun launched and the projectiles can provide a heat trace to the target and/or upon impact with the target the projectile breaks or shatters and leaves a heat signature on the target for up to several hours. Included with these heat chemicals may be optional chemlucents. This heat mark may be placed into a lethal and non-lethal projectile. This allows heavy and light armor targets, vehicles, buildings and personnel to be marked without extensive damage to the target and without seriously injuring a person. The target may now be heat marked and chemlucent marked.

Abstract: A non-lethal marker projectile that provides site identification capability of a target upon impact includes a rear base made of plastic and a front end extending longitudinally from the rear base. The front end defines a space therein and includes an outer surface having a rear portion attached to the base and a nose portion. The front end also includes a breakable container system located in the space which contains separated chemiluminescent reagents which when mixed produce light. The front end further includes a foam filler which surrounds the breakable container system and which fills the space. The container system breaks on a setback impact that is exerted during firing and initial launch, causing the chemiluminescent reagents to mix and be absorbed into the foam filler, such that upon impact of the projectile with the target, the foam filler marks the target with the mixed chemiluminescent reagents diffused therein.

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.

Abstract: A long-range training cartridge meets current US Army requirements. The long-range cartridge design enables its sub-projectile to be range limited to less than 8000 meters when fired at a 10-degree gun elevation. The long-range training projectile includes a three-piece aluminum or steel sabot with a similar exterior profile to the kinetic energy tactical sabot. The sabot encapsulates a light-weight sub-projectile comprised of a steel rod and an aluminum fin or cone. Since the sub-projectile is encapsulated in the sabot, it will not be subjected to differential pressures associated with interior ballistic gun gasses. As a result the sub-projectile will therefore have less bending and better flight characteristics. The sub-projectile meets the guidelines for target accuracy and precision at ranges beyond 3000 meters.

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.
