Magnesium alloys offer an attractive combination of good mechanical properties with very low density, making these materials strong candidates for structural applications such as gearboxes for rotary wing aircraft, as well as finding strong interest in the automotive industry for engine and transmission components.  Repair of such structures by additive manufacturing, as well as manufacturing of ...

The development of a burn-in process for high power MWIR and LWIR Quantum Cascade Lasers (QCLs) is proposed. The new burn-in process will be rooted in extensive statistical experimental data to be collected in Phase I and Phase II of this program. This will allow us to extract all the critical empirical parameters required for mean-time-to-failure (MTTF) projections for high power MWIR and LWIR de ...

Intelligent Optical Systems, Inc., in collaboration with Bowling Green State University, proposes to develop a field-rugged, eye-readable indicating spray solution that can immediately detect synthetic opioids over a large area of contamination (i.e., military vehicles, individual protective equipment, clandestine labs, etc.). The proposed chemosensor in a spray solution format will detect multipl ...

The growing demand for carbon fiber coupled with the high cost and energy input required to manufacture virgin carbon fiber provide substantial economic and environmental motivation for reclaiming carbon fiber from carbon fiber reinforced composites. However, the harsh treatment typically required for extracting carbon fiber from chemically cross-linked thermosetting resins greatly diminishes the ...

Detecting and Avoiding (DAA) manned aircraft from small Unmanned Aircraft Systems (sUAS) remains the unsolved problem for safe integration of sUAS into civil airspaces where Navy UAS must pay Due Regard to the laws of civil aviation. The difficulties are manifold. The solution requires both ultra-low SWaP sensors that track aircraft over long ranges, providing 360o field-of-regard (FOR), and often ...

As complexity and performance requirements increases for RF sensors and systems for electronic warfare applications, the need for innovative and low-power compressive sensing (CS) technologies will become urgent in power constrained mobile platforms. There are several DOD and government application areas where this holds true and the high-performance CS technology to be developed in this program c ...

Cornerstone Research Group Inc. (CRG) and the University of Dayton Research Institute (UDRI) propose to develop a System Ground-Fault Identification and Detection (SG-FIND) platform for naval shipboard three-phase radial power systems. These ungrounded and high-resistance grounded power systems allow for continued operation with a single line fault; however, a second line fault on another phase pr ...

The U.S. Navy is actively developing new High Temperature Superconducting (HTS) technologies to support its all-electric ship program. The HTS technologies being investigated by the Navy include power distribution cables, DeGaussing cables, (HTS-DG), unmanned Mine Sweeping (HTS-MS), motors/generators, and Superconducting Magnetic Energy Storage (SMES).For any of these HTS based systems, there is a ...

Both acoustic and electromagnetic waves exert forces of radiation on targets in their path of propagation. The radiation force (pressure) results from the change in wave momentum due to scattering by the target, averaged over one period of oscillation.  Modulated radiation pressure (MRP) utilizes the acoustic radiation force by using a double-sided suppressed carrier modulated (DSB-SCM) incident ...

Etegent proposes to evaluate, model and propose an improved acoustic radiation force exciter for underwater use.  This research into an improved exciter will offer increased force excitation suitable for exciting underwater objects such as unexploded ordnances and mines.  Techniques to utilize additional signals and features in the response signal will be evaluated. Future work will focus on the ...
