    摘要: A 40 mm ammunition projectile for firing without significant spin in an M203 or an M320 grenade launcher. The ammunition includes a projectile body having hollow inner cavity therein for an explosive warhead; a projectile fin assembly; a projectile nose element having a conically shaped front area thereon; a decoupled projectile sabot in two or more joining sabot petals enclosing the body; a base cartridge case having vent holes, a bowl area for placement of a copper closure cup containing propellant therein, and a closure plug for threading into the rear of said cartridge case. The projectile fin assembly may provide a canted angle on each fin blade to (relatively very slowly) spin up the round at less than 30 Hz. Projectiles with body length less than five inches may be launched in an M203 grenade launcher while projectiles with body length up to eight inches may be launched in an M320 grenade launcher.

    摘要: A rod sleeve made of smart material sleeves and/or steel sleeves with smart material rings surrounds the rod of a kinetic energy projectile. The rod may be made of DU, tungsten, or other material. Smart materials are materials such as nickel-titanium (nitinol) and copper aluminum nickel (CAN) that can be trained to change to one or more particular shapes at predetermined temperatures. The change in shape occurs on a molecular level, almost instantaneously. The rod sleeve can be made all or in part from smart material. The smart material is trained to shrink at cold temperatures and expand at hot temperatures. The sleeve may then be heated and expanded to allow the sleeve to be pressed on the rod. As the sleeve cools, it compresses and provides required support to rod during gun launch of the kinetic energy projectile. The sleeve heats up while traveling down range due to the aero-ballistic heating of the sleeve material. At this higher temperature, the sleeve expands. Upon projectile impact with the target, the sleeve minimally penetrates the target, allowing the rod to slip supported through the sleeve and penetrate the target. The sleeve supports the rod as it penetrates the target but does not inhibit its penetration, remaining behind as the rod continues to penetrate the target.

    摘要: An electronic light source system is employed to create a flame-less tracer for a munitions projectile. The electronic light source system may be positioned in various locations and combinations of locations on a projectile (e.g., front, back, side, etc.) to enhance visibility of the projectile during flight. The electronic light source system provides a light source on the projectile that is visible to an observer at various viewing angles throughout the projectile flight without the environmental or safety issues presented by tracers using pyrotechnic materials. After assembly, the present system is encapsulated in glass or clear plastic to G-harden the present system, enabling the present system to sustain the large loads and stresses induced by gun launch. The present system may comprise a variety of light sources such as, for example, lasers, high output light-emitting diodes (LEDs), strobe lights, etc. The present system is capable of flashing the light sources at a variety of frequencies (e.g., 5 Hz, 20 Hz, etc.) to further attract the human eye. In addition, the present system presents the substantial benefit of being able to project light at various wavelengths outside the visible spectrum.

    摘要: A system and method for improving the process of mechanical translation of projectiles by a spring mechanism that is built of a smart material and that is activated by an electric pulse, to provide a controlled translation of a projectile before firing or, in case of pre-firing termination, in order to restore the projectile to its original position after translation. The pre-firing translation using the spring mechanism provides a more controlled process and reduces the risk associated with the conventional propulsion charge translation design. The ability to return the projectile to its initial state after translation affords a significant advantage over the conventional propulsion charge design since it enables the projectile firing to be terminated even after translation, unlike in the conventional design whereby the projectile firing is irreversible upon a mechanical translation by setting off the propulsion charge.

    摘要: An energetic sabot allows part of the sabot to burn away at a controlled rate, adding propellant energy to the gun while at the same time completely support the projectile rod. The energetic sabot is thicker or larger at shot start to support the projectile without breaking. As the energetic sabot travels up the gun tube, the energetic sabot then thins out or otherwise decreases in mass as the force on the energetic sabot decreases. The weight of the projectile consequently decreases as it travels up the gun tube, allowing the gun gases to push a lighter projectile, giving the projectile a higher velocity. Due to its continually decreasing weight in the gun tube, the projectile experiences greater acceleration and exits the gun with a higher muzzle velocity. A secondary effect comes from increased pressure in the gun tube from the gases relinquished in the burning of the sabot, further increasing the velocity of the projectile. This higher velocity in turn leads to greater projectile velocity at target impact, and thus a greater penetration depth. The energetic sabot is “doped” with energetic materials by sprinkling either explosive, propulsive, or pyrotechnic agents between layers of the composite material in the energetic sabot. These agents ignite upon propulsion; their composition is determined from their burn rates. The burn rate may be designed proportional to the decrease in chamber pressure; the less pressure in the tube, the more material that can be relinquished.
