摘要:
The present invention uses aerodynamic heating caused by air-friction during flight of a training projectile. The training projectile includes a nose, a body and a tail section. The body has a forwardmost end secured to the nose, and a rearwardmost end secured to the tail. Air friction during flight causes deployment of “passive” shape memory alloy (SMA) aerodynamic members in an assembly to induce drag of the training projectile thereby limiting an effective range of the projectile.

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.

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.

A single multipurpose ammunition projectile/warhead is provided, which has the capability of clearing a variety of different types of hardened targets. The single projectile of this invention may be used for breaching steel reinforced concrete walls; may be used against light armor targets; may be used for defeating bunkers; and may also be used for antipersonnel applications. Huge savings in time, money, inventory and logistics are realized through utilizing only this one multipurpose ammunition against all these types of targets. This multipurpose projectile, among other superb capabilities, is able to puncture an eight inch double steel reinforced concrete wall timed to then have its warhead explode into fragments. This allows fragmentation in a more effective, nearly ideal direction. The projectile warhead of made of extremely thick walled 300M steel; with the projectile center of gravity to be located equidistant between a pair of bourrelets, for increased stability.

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. The tracing/marking system may also use various shaped projectiles such as stars, cubes, balls or flechettes. The chemlucent chemicals used by the tracing/marking system are non-flammable, biodegradable, and non-toxic.
摘要:
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.

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.

A projectile to be, fired from a non-rifled tube includes an elongated foody and a stabilizer secured to the tail end of the forebody for enhancing the projectile flight stability and for imparting spin to the projectile. The stabilizer includes a threaded member that extends integrally into a forward section, a peripheral channel and a grooved aft section. The forward section has a generally smooth cylindrical shape. The peripheral channel extends along the entire peripheral contour of the stabilizer and has a generally semi-circular cross-section, for generating an expansion wave and for directing air flow toward the grooved aft section. The grooved aft section is cylindrically shaped relative to a longitudinal axis, and has a predetermined number of identical, equally spaced, circumferentially positioned grooves which traverse the entire axial length of the aft section, and which are angled relative to the longitudinal axis. Each angled groove is defined by two substantially parallel side walls.
摘要:
A cylindrical device connected to the nose of a projectile for imparting n to the projectile fired from a non-rifled bore of a cannon. The device has at least two coaxial, adjacent, and integrally connected cylindrical segments of different diameter. The segment having the larger diameter is positioned most rearwardly of the projectile, relative to the nose of the projectile, and the periphery of this segment has circumferentially spaced angled slots for catching air moving past the projectile to spin the projectile. The segment with the smaller diameter attaches the cylindrical device to the aft end of the nose of the projectile and directs the flow of air to and through the angled slots of the segment having the larger diameter.
