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 ...

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) ...

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 ...

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 objective of the proposed effort is to develop a systematic approach for building reduced-order models (nonlinear coupled finite-degree-of-freedom equations) capable of reliably modeling and predicting limit cycle oscillations (LCOs) and using these models in LCO management procedures. The models will be developed by combining (a) physical observations from ground vibration, wind tunnel, and ...
