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 PointMethod) - MFM (Multiphase Flow Method) approach and the CartaBlanca nonlinear solver environment developed at Los Alamos National Laboratory. Car ...

The proposed project will demonstrate the feasibility of developing a data driven prognostic fault tolerant smart weapon system concept for the Airborne Laser. A real-time prognostic health management (PHM) system will be developed to track the likelihoodof future system or subsystem failures and initiate or indicate appropriate actions to maintain or optimize system performance. A library of pr ...

The program objective is to develop and evaluate a prototype spectral polarimeter that could be used as an ISR sensor package on organic UAVs. The sensor employs advanced, visible-band technology to support littoral-zone warfare mission products, such asoceanographic characterization in VSW, including the surf; detection and characterization of stealthy or intrinsically low-contrast targets such ...

In Phase I, AVYD DEVICES in collaboration with SRI International, will demonstrate the feasibility of our modeling approach to predict material properties and device performances using experimental parameters of growth and fabrication processes formulticolor HgCdTe detectors. The models will include point defect-dopant interactions; Fermi dopant diffusion; interdiffusion (including Fermi level ef ...

Multiplexed Time-of-Flight Mass Spectrometers, such as the Hadamard Transform TOFMS (HT-TOFMS), show great promise in increasing MS sensitivity and spectral acquisition speed. Multiplexing the ion beam allows multiple ion packets to simultaneously coexistin the instrument flight tube, advantageously changing a pulsed TOF-MS into a continuously operating instrument. The heart of a HT-TOFMS, and t ...

The petroleum refining industry tends to utilize large sulfur removal units, which are permanently installed and unable to meet the demands of a versatile industry. Cal Nova Tech has developed a sulfur-removal concept that utilizes portable, modularcomponents that can be quickly assembled in a variety of ways. These units are especially effective in confined areas, such as those found onboard Na ...

The objective of this proposal is to develop a low cost infrared imaging array for the 3-5 micron window. Current infrared imaging sensors are optimized for the 10 micron regime which corresponds to the wavelength emitted by a warm body (e.g. human). Theproposed lower wavelength regime would target hotter sources such as vehicle exhaust or other machinery indicative of human activity without req ...

The Phase I program objectives were successfully completed. In addition, novel ideas were developed that will be of use in the Phase II program and in the field of algorithm development and sensor characterization in the laboratory. Work on new algorithmswas initiated to optimize wavelength selection for vapor and aerosol detection, a detailed design for obtaining sensor detection statistics in th ...

A collaborative effort between the Eddy Company and The Johns Hopkins University Applied Physics Laboratory (JHU/APL) is proposed to develop an affordable silicon-based visible to near infrared missile warning sensor. This sensor whould unltimately bepart of an Infrared Counter-Measure (IRCM) system designed to protect Naval aircraft from anti-aircraft missiles.In this effort we will complete a f ...

Low-power Hall thrusters offer potentially important advantages for certain military applications but issues of lifetime and efficiency degradation at lower powers are issues hindering its utilization. A factor impacting efficiency is that thestate-of-the-art techniques for electron generation used for neutralization (such as hollow cathodes operating on the same propellant as the thruster) do no ...
