The device includes a pair of shaped coils one of which is evaporated to form the plasma and the other coil provides the electromagnetic force field to influence the characteristic arc symmetry and the energy coupling between the plasma and the surrounding combustible mass.

Abstract: The invention provides an improved passive armor system. The armor system uses armor stacks of ceramic tiles connected to layers of glass. The armor stacks are then adhered to the inside of a cover box. The cover box is then secured to a base and then covered with a cloth impregnated with an adhesive.

Abstract: The invention provides a water jet system with higher efficiency and better steering. The water jet system uses cantilever bars for an inlet grating, to prevent blockage. The water jet system also uses an elliptical impeller shaft housing to reduce turbulence and snagging of debris by the rotating impeller shaft. The water jet system uses impeller blades with a curved cross section that curves towards the direction of forward rotation. The water jet system uses U-shaped flanges mounted to the outlet of the water jet to provide steering.

Abstract: This invention pertains to a method of rear drive conversion of the M113 family of vehicles to provide a light, mobile and tactical hybrid vehicle. The method includes stripping an M113 to a base aluminum hull and providing modified or newly fabricated parts to enable the conversion. Using the rear drive conversion process disclosed herein, critical operations parameters such as volume under armor, mobility, air transportability and vehicle performance efficiency per unit weight are significantly increased.

Abstract: A simulation engine for temporally driven functional causal model application program is disclosed. An object oriented approach is used to create model definitions in which a system of interacting agents are assembled into a tree structure of agents and subsystems. The interacting agents which exhibit or endowed with time dependent behaviors are identified and are given priority in a queue. The temporal nature of the interacting agents and other characteristics are considered in the simulation of the model.

Abstract: A ballistic grille structure is combined in a stacked array with a similar grille structure to yield ballistic performance capability greater than the ballistic performance capability of the original grille structure. The grille structures may be of the type currently used in single, unscathed deployments with each grille structure a truncated version of the current structure such that a synergistic projectile defeating capability is realized by the stacked array of truncated grille structures.

Abstract: This invention relates to a material handling system. More particularly, the invention pertains to the method and apparatus for automatically loading a two-piece ammunition into a gun tube. A continuous rammer mechanism having a plurality of strategically spaced pawls is structured to accelerate the two-piece ammunition into the gun tube. The system compensates for different angles of gun trajectory by adjusting the speed and output of a drive motor to thereby provide a consistent ramming acceleration of the ammunition.

Abstract: The invention provides an amphibious vehicle that integrates suspension fairing with a movable bow vane. This integration, allows the suspension fairings to be stored between the bow vane and the hull of the vehicle during land use and to be automatically deployed during water use. The suspension fairing uses a deployment system connected with the bow vane deployment system, so that they are deployed and retracted as an integral system.

Abstract: This invention relates to an EMI and EMP shield configured to arrest electromagnetic contamination of sensitive electrical and microprocessor equipment. Particularly, the present invention enables a positive dynamic seal for moving parts and joints by means of resilient and self-adjusting conductive contacts. The contacts provide electrical bonding, between otherwise separate and electromagnetically leaky joints, to arrest EMI and EMP contamination.

Abstract: The invention provides a grille armor system for use on a armored vehicle. The grille armor system adds an applique grille to a grille to increase the protection provided by the grille armor system. The applique grille is designed to add a minimal profile. The applique grille also is designed to allow maximum air flow through the applique grille. In the preferred embodiment, the applique grille is made of 4 mm thick steal bars place 8 mm apart to provide added protection to aluminum S-shaped louvers against high velocity 20 mm fragment simulating projectiles.

Abstract: A center mounted power train configuration for a high water speed tracked amphibious vehicle which mounts the engine above the waterjet inlet plenum to shorten the power train length, so as to allow the vehicle length and weight to be optimized for land and water mobility. The short power train length provides for use of alternate longer components which may be required to obtain adequate power and thrust. Center mounting the power train reduces air ingestion into the waterjets and maximizes the sharing of support structure to lighten the vehicle. Center mounting of the power train also optimizes efficiency by using one propulsion gearbox to transfer power and improves access to components for repair or replacement. The power train arrangement features a rearward center of gravity for enhanced land and water mobility and provides space for locating personnel, for mission equipment and for access to floor level suspension components.

The invention provides, inter alia, a training aid for study, evaluation, design and maintenance of a system.

Abstract: A method, apparatus and article of manufacture is disclosed for using stand-up expanded metal armor members for protecting vehicles or other objects from ballistic threats. One or more spaced expanded metal member has projectile engaging faces which present sharp edges and arcuate surfaces to the small point of the projectile. When the point of the projectile engages the faces of the expanded metal members, the projectile is progressively deflected or shattered causing the wide arcuate side surface of the projectile to stop the projectile, or to pass through some or all of the members and engage the protected object with less than lethal force.
