In this STTR program, Photonic Systems Inc. and Prof. Jacob Khurgin at Johns Hopkins University propose novel optical external and internal fiber cooling approaches to efficiently cool the high power GaN microwave amplifier. The external cooler is a single end, square-shape, Yb:ZLAN fiber with high reflection (HR) coated surface which can attach to the amplifier surface and create a cold spot at t ...

Future naval operations are expected to make extensive use of unmanned vehicles to support a range of operations, including intelligence gathering, mine warfare, force protection, and anti-submarine warfare. Current unmanned systems are typically controlled remotely by an operator who directly manipulates a control interface for the vehicle. The effectiveness of this approach is obviously limited ...

The implementation of structural health monitoring (SHM) systems into naval applications has been hindered due to component quantity, including sensors, power/communication cables, and acquisition/computation units, as well as data quality. Particularly for large-area applications such ship hulls, complexity of implied system infrastructure can be impractical, and data can be worthless with attenu ...

Busek Co. Inc (Busek) and Massachusetts Institute of Technology (MIT) propose to develop the design of a photon actuated, ultrafast carbon nanotube (CNT) field emission cathodes for high-power electron beam accelerator sources. The cathode will be based on massive arrays of Vertically Aligned Carbon Nano-Fibers (VA-CNFs) that are individually controlled by a vertical ungated field effect transisto ...

SI2 Technologies, Inc. (SI2) proposes an innovative solution to the Navy’s need for wideband antennas to support naval ships and Marine Corps’ vehicle communications, electronic warfare (EW), and radar functions. SI2 will develop efficient, broadband, metamaterial antennas for operation in the VHF-UHF frequency range. These antennas will initially be designed for integration with the composite ...

Icing is among aviation’s most serious weather hazards because it renders aircraft unflyable before flight and severely reduces aircraft performance during flight. Existing approaches for mitigating ice accretion on leading edges, such as the inflatable boot and liquid deicer can significantly increase weight, power requirements and manufacturing complexity without providing sufficient reliabili ...

Ferro Solutions has demonstrated in Phase I that ferro fluids can be used to create a self-pumping cooling system that can extend the life and improve performance of highpower transducers or other electro-mechanical devices. In the Phase I demonstration a resistor submerged in a ferrofluid was powered so that its temperature increased to over 1200C. Upon introduction of the appropriate magnetic fi ...

This NAVY Small Business Technology Transfer project is directed toward the development of a novel hydrogen generator that employs nanostructured metal foam catalysts. Special coating and form factor will also be employed to the hydrogen generating materials to ensure the safety of storage and transportation, while maintaining very high packing density compared with conventional powder packing.

The primary objective of the proposed effort is to develop a validated computational tool to predict the afterburning of non-ideal munitions containing metal and hydrocarbon fuels. The activities outlined devise a well-coordinated collaboration among researchers from Reaction Engineering International (REI) and the State University of New York at Buffalo (UB). The activities proposed will build on ...

We propose to develop scaling relationships for reaction violence in the cook-off of energetic materials such as explosives or propellants. This will be accomplished by a coordinated effort consisting of data review and analysis. The anticipated results include key non-dimensional parameters that incorporate the thermo-physical, flow, thermodynamic, and kinetic properties of the material, the heat ...
