Abstract: An asymmetric ERA box improves the disruption of a shape-charge jet for a high-explosive projectile for a given mass requirement and stand-off distance. Mass is asymmetrically redistributed from the outer plate to the rear plate in the form of increased thickness of the rear plate. This is offset by forming the outer plate of a low-density material that provides an impedance mismatch sufficient to attenuate the shockwave of low velocity projectiles (e.g., 50 caliber bullets) so that they embed in but do not detonate the explosive. The outer plate provides negligible disruption of the shape-charge jet with substantially all the disruption being provided by the thicker high density rear plate. Placement of substantially all the mass toward the front of the shape-charge jet improves overall performance of the ERA.

Abstract: A supercapacitor-like device is described that uses a porous, conductive foam as the electrodes. After the device is charged, an explosive wave front can be used to remove electrolyte from the metal foam. This creates a large net charge on each electrode, which will readily flow through a load placed across the electrodes. The removal of charge can potentially occur on a time scale of microseconds, allowing a supercapacitor to be used in pulsed power applications. The creation of this net charge requires significant energy, meaning this concept may also be suitable for removing kinetic energy from objects.

Abstract: This invention concerns a device for the transmission of impulse and momentum, e.g. from a shock wave from an explosion or momentum from objects impacting the device, from one location to another, and is primarily used to protect vehicles, ships, aircrafts and buildings against impulse and/or momentum, for instance in regards to attacks on those with grenades, bombs, mines and the like.

When the receiver 1 is accelerated by the incoming shock wave 9 it collides with the transmitter 2, connected to an emitter 3, momentum is transferred to the emitter 3. If the transfer is in itself not sufficient to bring the receiver's 1 velocity to an acceptable level, additional energy and momentum is added through the transmitter 2.

Abstract: Bar armor currently provides a means of providing partial protection of vehicles and structures against certain types of Rocket Propelled Grenades (RPGs). However, the individual bars must provide enough strength to cut through or deform the outer ogive of an RPG and cause electrical contact with the inner ogive. This in turn imposes constraints on the overall effectiveness of the system and how light it can be made. These constraints can be eased by providing cross-attachments for the bars, provided that the cross-attachments themselves are mutually supporting and of low enough density and sufficient frangibility to avoid detonating the RPG when they are struck by the RPG nosepiece, which contains a piezoelectric element that causes the fuse of the RPG to function. Through this means, bar armor can be made lighter, more effective, and easier to see through.

Abstract: A vehicle occupant blast isolation system uses small explosive charges and small rocket motors to isolate vehicle occupants from blast loads. The system initiates the explosive charges to remove all mechanical linkages between the occupants and the initial shock so that no shock effects are transferred. The system counteracts the effects of the impulse by igniting the rocket motors to provide a restoring force to counter the effects of the impulse load. This combination of mechanical isolation and impulse negation addresses both the high-frequency initial shock and low-frequency impulse effects from explosive devices.

Abstract: A gas producing device comprising a ferroelectric (FEG) or ferromagnetic (FMG) generator material wrapped by a conductor, wherein the conductor is in contact with a dielectric material. A ferroelectric or ferromagnetic generator material is polarized or magnetized. When a shock wave impacts the FEG or FMG, the polarization or magnetization of the material is rapidly destroyed. The rapid destruction of the magnet by breaking it into small pieces causes the magnetic field to go to zero very quickly. When the field changes quickly it induces a high current through the wrapped conductor or coil. When the current passes through the conductor in contact with the dielectric material it generates heat and vaporizes the dielectric material creating a high pressure gas. A reactive armor may comprising a gas producing device comprising a ferroelectric (FEG) or ferromagnetic (FMG) generator material wrapped by a conductor, wherein the conductor is in contact with a dielectric material.
