This STTR project will develop and validate a robust, scalable computational capability for the simulation of weapon-target interactions of interest to the Army. The proposed algorithm is based on the FLIP (Fluid Implicit Particle) - MPM (Material Point Method) - MFM (Multiphase Flow Method) approach and CartaBlanca nonlinear solver environment developed at Los Alamos National Laboratory. CartaB ...

Our Phase II goal is to develop (model, design, fabricate and test) a miniaturized biofuel cell capable of generating energy from biomass to power the OFW sensor suite. Phase I goals were successfully met by demonstrating a prototype using glucose as fuel. In contrast to conventional technologies, this biobattery promises to be compact/lightweight, require little/no logistical support (re-supply ...

Theoretical investigations and technology developments during last years have created new conceptual approach to design and build a new class of plasma wave electronics detectors of terahertz (THz) wave range. Terahertz radiation corresponds to the frequency bands of molecular and lattice vibrations in gases, fluids, and solids. THz detectors with higher sensitivity is urgently need for important ...

This proposal is concerned with the development of an advanced three-dimensional simulation facility for the analysis of environments such as produced by high-velocity impact of kinetic energy penetrators under the Army STTR Program. This facility will enable the Virtual Testing and Design of Military Systems with increased survivability as demanded by the Army's Future Combat System (FCS) and Obj ...

We have developed a novel type of military obscurant that is based on the fabrication of composite particles with precisely defined geometries. These particles have very high infrared extinction efficiencies with peak extinction wavelengths that are directly correlated to the major and minor dimensions of the particles. By combining populations of particles, obscurants clouds can be produced that ...

We have developed a cost-effective process to improve the dissemination of particle-based obscurants. Surface coatings with defined chemical properties improve the obscurant dissemination characteristics by reducing inter-particle binding forces. This encapsulation method protects the particles from structural damage incurred during processing and dissemination, thereby improving their functional ...

Surface Optics Corporation (SOC), teamed with the University of California, Irvine, proposes an exploratory study aimed at the development of an inexpensive portable optical tagging system with an intelligent retro-reflective encoded tag, dynamic modulator, and sensors needed for tracking and identification of U.S. military assets. The encoded tag can be either affixed to, or printed onto, milita ...

A suite of sensors is required to detect, analyze, track, and report position, speed, and direction of travel of watercraft in interior waterways. WaveBand's millimeter-wave sensors have demonstrated the capability to provide watercraft data whose attributes contain the position, speed, and direction of travel of these objects. The sensors are also capable of furnishing near-photographic quality ...

From consultations with the Army program manager, it was determined that the Army has a strong need for improved amplifiers in the W band. Accordingly, the proposed Phase II overall technical objective is to develop a 10 W, W-band prototype planar helix TWT. In Phase I, we addressed improving the repeatability, cost and yields of conventional Ka-band TWTs by introducing novel circuits, beam sou ...

Situational awareness is a critical factor for the soldier in the field. An acoustic source localization system can greatly benefit the soldier by detecting threat and displaying its location. The goal of this proposal is to study a promising algorithm based on a biologically inspired technology and verify its ability to perform in various environments and with multiple sources. The proposed ...
