Phase Transition Explosive Driven Pulsed Power Generators

DOD / ARMY
This SBIR proposal is intended to address the experimental development of Shock Wave magnetic flux compression Generators (SWGs) for applications to be used in the US Army's multifunction munitions. The US Army requires high-energy density power supplies that are capable of functioning properly in high G environments. Conventional magnetic flux compression generators (FCGs) probably cannot be adequately hardened to operate under these circumstances. However, a variant of the FCG technology, namely shock wave flux compression generators (SWGs) hold the promise for being able to survive the high G launch needs of the US Army. These generators work by using the phase change of a working material under strong shock conditions to perform work on a magnetic field. To date, the only experimental research appears to use implosion systems to create high magnetic fields. However, for SWGs to become useful power supplies, divergent geometries must be shown to be able to compress the magnetic fields. We intend to develop the SWG for the Army's directed energy applications. While the hydrodynamic computer codes CTH and ALE3D will be used, the emphasis will be on the experimental testing of the generator designs, differing working materials, and various explosives. Thus, within the Phase I of this effort, SWGs will be designed, fabricated, and dynamically tested. If appropriate, a second set of tests will be performed during the Option period. Phase II development will examine the use of SWGs to power directed energy devices of interest to the US Army. Phase III development will extend this effort by working with the US Army and its contractors to provide useful solutions for Army requirements.
