The proposed research program aims to develop a physics-based identification, modeling and management infrastructure for aeroelastic limit-cycle oscillations. This infrastructure will be built upon high fidelity state-of-the-art theoretical/computational methods as validated and verified by available experimental data bases, and will include (1) rapid flutter boundary determination for a wide ran ...

During Phase I, we have conducted proof-of-principle experiments to fabricate exchange-coupled isotropic permanent magnets with SmFeN-Fe4N compositions employing shock wave consolidation technique. We have also successfully synthesized nearly 100% Fe16N2 in bulk form. Under this Phase II plan, we propose to optimize and further enhance the isotropic exchange-coupled permanent magnets with higher e ...

Antennovation and the Pennsylvania State University propose to develop novel new electromagnetic bandgap (EBG) materials in conjunction with miniaturized broadband antennas for use in man-portable antenna applications. The proposed antenna/EBG system will be designed to be low-profile, compact, and light-weight for helmet-mounted antennas and/or other body-worn applications. The frequency range o ...

Laser Induced Breakdown Spectroscopy (LIBS) is being successfully transitioned to field applications in both close-contact (proximity) and standoff detection modes. LIBS is attractive since it can be used to detect a wide range of chemical, biological and explosive (CBE) hazardous materials. While LIBS is well suited to evaluation of complex hazards, including improvised explosive devices (IEDs) ...

Understanding the right thing to do in the battlespace is contingent on knowledge of the terrain and its tactical importance for military operations (e.g., terrain restricts or enhances abilities to observe, move, and shoot). The product of this Phase II effort will be TAH-RI, a COTS software component for systems developers, enabling them to easily make systems capable of identifying terrain fea ...

Crystalplex has developed novel semiconductor nanocrystal technology that can be a platform solution to meet the Army's desire for a light emitting diode (LED) with enhanced output in the deep green region using nanoparticles. This innovation produces an efficient deep green (555-585 nm) nanoparticle emitter capable of sustaining the Army's stated goal of 120 lumens per watt of input power. Crys ...

The design of Unmanned Aerial Vehicles (UAV’s) is a complex process of creating a reliable system of reasonable cost that can survive in hostile environments. Although UAV’s have unique aspects to them, similar goals can be found in almost any complex, competitive product. One aspect of the design of these systems that tends to be both difficult and poorly supported with available computer ...

The main objective of this program is to develop a new class of high performance hard magnetic materials that will maintain an energy product of 30 MGOe or greater at temperatures up to 450 °C. These novel magnetic materials are greatly needed for the "more electric" airplanes and space vehicle applications where a high operating temperature is a strict requirement. The approaches to be used for ...

Electron Energy Corporation and University of Delaware propose to develop multiphase nanocomposite magnets with room temperature maximum energy product potentially up to 100 MGOe for high temperature applications. Multiphase nanocomposite magnets could take the advantage of the extremely high coercivity of SmCo alloys, the high saturation magnetization and moderate intrinsic coercivity of other ha ...

The use of coated HT superconductors in the ac windings of electrical machines offers the possibility of much lighter electrical devices. To use these conductors at proposed high frequencies, present “as-manufactured” conductor geometries must be modified to reduce their ac loss by using fine filaments and other topologies). Equally important are more global winding losses requiring suitable ...
