THE PROPOSED PROGRAM USES POLARIZATION REVERSAL ON FERROELECTRIC MATERIALS THAT YIELD CURRENT DENSITIES IN THE kA/cm2 RANGE. THE FAST CHANGE IN THE POLARIZATION VECTOR WITHIN THE MATERIAL RESULTS IN A TRANSITION THAT LIBERATES THE POLARIZATION INDUCED CHARGES (4 P) RESULTING IN A CURRENT PULSE LIMITED ONLY BY THE TRANSITION TIME AND SPACE CHARGE EFFECTS. THE PROPOSED PROGRAM WILL DEVELOP THE TECHN ...

The advanced technology described in this proposal promises to increase the performance of laboratory and, specifically, tabletop x-ray lasers by up to an order of magnitude. Such gains in performance coupled with compact technology will lead to the introduction of the world s first table-top, commercial x-ray laser. Tetra proposes to develop an advanced driver for the laboratory laser based upo ...

A NOVEL MILLIMETER WAVE TERMINAL GUIDANCE IS PROPOSED, WHICH IS UNIQUELY SUITABLE FOR SMALL SPINNING PROJECTILES. THIS GUIDANCE CONCEPT DOES NOT REQUIRE INERTIAL COMPONENTS. IT UTILIZES THE INHERENTINERTIAL PROPERTIES OF PROJECTILE SPIN NUTATION. THE CONCEPT CAN BE IMPLEMENTED WITH VERY LOW WEIGHT AND VOLUME, AND PROMISES PROJECTILE COST SAVINGS OF AN ORDER OF MAGNITUDE. APPLICATIONS OF THIS NOVEL ...

This proposal addresses the exploratory development and evaluation of novel thin film and/or monolithic detonators as diverters for guided spinning projectile use. A number of such detonators comprise a diverter technology termed RMDM, (for Ring Matrix Diverter Module) which, along with the SSPG (for Small Spinning Projectile Guidance) seeker, forms the basis for inexpensive miniature guided proje ...

Demand for micrometer size metal powders is increasing rapidly as new technologies emerge which can make use of their unique characteristics. One rapidly growing application requiring such powders is metal injection molding, a powder metallurgy process for forming near-net-shape components with higher dimensional accuracy than earlier processes. A significant need also exists for micrometer size s ...

BMDO seeks development of novel methods to cut tabrication cost of metallic spacecraft and interceptor structures. UTRON proposes to develop an innovative rapid powder consolidation technique called Combustion Driven Dynamic Consolidation (CDDC) to consolidate metal (and other) powders. This technique is versatile and can be applied to various material systems such as metal and alloy powders, inte ...

BMDO seeks development of novel low-to-no outgassing joining/bonding techniques for advanced composites. Explosive welding, employing actual chemical explosives, is a versatile process that can be used, in principle, with any two materials. In some situations involving difficult materials, explosive bonding is the only practical joining method. Typically, a layer of explosive is carefully coated o ...

Strait pointing accuracy for the antenna and reflector of spacecraft requires structural materials with excellent stiffness and dimensional stability. Carbon-carbon (C/C) composites are prime materials for space applications because of their unique properties. Current C/C processing techniques are very expensive and time consuming. This Phase I research proposes a new class, low-cost graphitic mic ...

Reconfigurable computing architectures based on Field Programmable Gate Arrays (FPGAs) offer extaordinary real time processing rates in inexpensive programmable hardware. The key to using FPGAs for reconfigurable computing is to reformulate algorithms in terms of parallel operations that are easily implemented with chains of simple processing elements. Currently available commercial integrated cir ...
