Abstract: A tactical obscurant device having an obscurant payload that comprises a plurality of powder particles radially pressed within a cavity of the obscurant device using a pulsed radial dynamic magnetic compaction process to provide a packing density of at least 40%, such that the obscurant payload has a greater packing density over traditional packing processes, which results in an increased obscurant cloud size upon detonation that is capable of screening in at least one range of the electromagnetic spectrum. The obscurant payload may be comprised of a single powder material, at least two layers of powder material, or may have a multi-layered packed structure using different types of powder materials that are packed concentrically for multispectral obscuration upon detonation.

Abstract: This invention relates to a transformer and more particularly, to a system and method for making a transformer utilizing dynamic magnetic compaction. A coil is placed in a conductive container, and a conductive powder material, such as ferrite, is placed in the container and surrounds the coil and the turns of the coil. A power supply energizes a capacitor which subsequently provides a high energizing current to a second, energizing coil within which the container, material and inner coil are situated, thereby causing the container, powder materials and coil to be compacted to provide an electrical component, such as a transformer, motor, commutator, rotor or choke.
