    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: 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. After the self destruct phase however, each disk is separated from adjacent disks on either side by a spring mechanism that enables separation after the process is initiated in flight when the Nitinol wire deforms due to heating from air drag. Each disk then proceeds alone with low enough terminal kinetic energy on the ground to be less than lethal.

    摘要: A finless cone-nosed, ogival-nosed, or combination ogive-cone nosed training projectile is statically stable, yet has adequate spin rate to compensate for aerodynamic or mass asymmetries. In addition, the training projectile can be fired from smooth bore or rifled cannons of various calibers, including 120 mm and 105 mm. Spin torque and stability augmentation are provided by a radially angled slotted tail flange attached to the rear of the training projectile, providing high performance and improved accuracy at low cost for use in training exercises. The training projectile has a higher static margin than conventional devices, and provides the ability to train personnel with a training projectile that achieves flight ranges similar to its matching tactical projectile, and has improved accuracy.

    摘要: A length of a rod of an axial kinetic energy projectile is increased as the projectile flies to the target. The projectile includes a nose, a rear, and a base rod. The base rod has a forward member, a rearward member, and a connection between the forward member and the rearward member which allows the forward member to move axially relative to the rearward member from a contracted position where the rod has a reduced length to an extended position where the rod has an increased length greater than the contracted length. Further, the base rod includes a locking mechanism which axially locks the forward member and the rearward member together when the forward member is moved from the contracted position to the extended position.

    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.

    摘要: A stacked, collaborative engagement ammunition round is presented. The round includes plural stacked miniaturized projectiles where such projectiles separate after launch and then swarm as a group towards a target or targets. At launch, the projectiles may fly in a preselected formation, leader-follower towards the target. Or, the projectiles may deploy propellers, tri-copter or quad-copter vanes, and self steer swarming to the target. Each projectile has its own miniaturized guidance, navigation and control components, autopilot, cameras, transmitter, receiver, antennae, power source, sensors, fuzes and/or flex circuits.
