ABSTRACT: PaneraTech, in partnership with UCLA, is proposing to develop an extremely small UHF antenna based on Multiferroics. The Multiferroic (MF) concept allows for a sub-wavelength (

ABSTRACT: Echo Ridge proposes to develop a suite of EW training tools to support realistic warfighter training in the congested and contested RF environments expected in future operational engagements. The tools consist of an opposing force broadcast capability, an EMS monitoring capability and an analytical framework for configuring and scoring the behavior of the tools and participating warfig ...

This DOD Phase I STTR program would develop III-V multijunction based solar cells, using Virginia Tech"s InGaP/GaAs/InGaAs multijunction cells technique in combination with NanoSonic"s pioneering Hybridsil antireflection copolymer nanocomposite materials, which afford high levels of antireflection, temperature and abrasion resistance, impact durability and hydrophobicity (self cleaning). Such an a ...

Most of current available methods for prediction of fatigue failure -such as cumulative damage models, cyclic plastic energy hypothesis, crack propagation rate models, and empirically-derived relationships -are based on empirical relations and their application requires many unknown parameters that must be experimentally determined or calibrated for specific locations/critical areas. Also, the afo ...

The major objectives of the Phase I effort will be focused on CDC higher pressure combustion (using natural gas or hydrogen-GREEN MANUFACTURING) driven powder compaction fabrication of select alloys for Microwave Tube Related Component end uses for NAVY using powders of varying sizes and vacuum-grade purity such as Cupro-Nickel, Stainless Steels (e.g., 316 LN, Custom 465 high strength version), Mo ...

A database-driven approach is needed which characterizes the failure modes of the mechanical components of submarine systems under extreme loadings. Such an application must provide automation of the component shock qualification process through an automated capability while providing component-level qualification based upon similarity of components and failure modes. Certification of shock worthi ...

The Fixed Submarine Broadcasting System is a low frequency (LF) and very low frequency (VLF) communication system that provides independent and survivable connectivity to the United States Navy nuclear submarine force. The Navy operates six high powered VLF and seven LF transmitter facilities at different locations around the world. These outdoor transmission antennas operate at extremely high pow ...

Naval vessels which regularly encounter sub-freezing environments experience superstructure ice accumulation which has negative effects on seaworthiness, deck safety, and ship system performance. In order to mitigate risks to mission success, this ice is currently removed with tools and de-icing solvents through a hazardous manual process with risk of damaging ship components. Ideally, these de-ic ...

In order to maintain acoustic advantage, submarine crews need to assess acoustic vulnerability for historical and planned tracks and own ship noisy evolutions. A TDA or TDAs that produce acoustic advantage and vulnerability overlays for the geographic plot are essential to this. Our Phase I effort will develop a MATLAB-based TDA tool engine that when provided with the required inputs (own ship, en ...

Advanced effective Micro-glider development will be conceived under this Phase I effort.
