ABSTRACT: The overall goal of the proposed effort is to develop and demonstrate a general-purpose, fast, and reliable management and learning software tool for analyzing massive data sets generated by dynamic multi-disciplinary simulation. In Phase I, key technology elements were developed and proof-of-principle was successfully demonstrated. Data management software encapsulating salient feature ...

The project will remove a key difficulty that currently hampers many existing methods for computing unsteady electromagnetic waves on unbounded regions. Numerical accuracy and/or stability may deteriorate over long times due to the treatment of artificial outer boundaries. We propose to develop a universal algorithm and software that will correct this problem by employing the Huygens' principle an ...

ABSTRACT: The goal of this project is to develop theoretical models for electrode erosion in high-pressure arcs and incorporate them into computational tools for simulations of arc heaters. The complexity of the electrode material removal process is associated with the multi-phase nature of the arc-electrode interactions, melting and vaporization of the electrodes near the arc foot. Available mod ...

Yardney will design and develop a lightweight, safe, reliable, and cost-effective aircraft battery with improved thermal design and the use of active cooling techniques. As a novel part of the battery design, Yardney will investigate and implement high performance electrodes using three dimensional (3D) micro-porous current collectors, safer thin metal case cell design, a micro-channel heat pipe t ...

In this Phase I effort, HygraTek will explore a novel anti-ice coating formulation to develop icephobic surfaces for naval ship superstructures, decks, equipment and vehicles on board naval ships, e.g. fighter jets, helicopters etc. HygraTek has recently developed a series of different environmentally safe, non-fluorinated, transparent, icephobic coatings. These coatings display the lowest ice-adh ...

Virtual EM is proposing a solution for achieving electrically small high-efficiency VHF transmit antennas suitable for use on medium size Unmanned Aerial Vehicles (UAVs). In the proposed approach, maximum use of the UAVs airframe for the antenna improves radiation efficiency while dynamic reconfiguration of the antenna aperture provides frequency tuning and hence lower noise floor. Feasibility has ...

The aim of this STTR program is to develop protocols to discover rare-earth-free/rare-earth-lean magnetic alloys for replacing rare earth (RE) -based alloys for reducing the dependence of supply from China. The development of non-RE high temperature magnetic materials is very challenging. In Phase I, CFDRC in collaboration with its university partner has demonstrated a proof-of-concept computation ...

In this STTR proposal, we propose a novel computational technology for analyzing millimeter wave and sub-millimeter wave scattering from complex and electromagnetically extended objects and environments. The core of our formalism lies in a technique for rapidly calculating and coherently adding fields produced by different scatterer constituents, ranging from conducting, flat surfaces to penetrabl ...

The technical objective of this proposal is to demonstrate a Quantum Cascade Laser (QCL) emitting in the 3.0-3.5 & #181;m wavelength region, which employs a metamorphic buffer layer (MBL). It is the goal of this program to develop a QCL single-stripe device which will operate in a single, diffraction-limited lobe under room temperature continuous-wave (CW) operation to moderately high (~ 0.5 W) ou ...

The objective of this proposal is to develop an advanced Course of Action (COA) recommender that supports decision making. It is impossible for Warfighters to manually utilize the vast quantities of data at their disposal. To this end, advanced algorithms and data visualization are required to aid in analyzing the data and making informed decisions. The final output of such a system is actionable ...
