Recent advances in directed energy weapons (DEW) require radar systems to implement front door protection against high power signals. Although nonlinear protection elements have been successfully employed in the past, fast ultra wideband (UWB) and high power microwave (HPM) signals are not successfully blocked by most current circuit protection technologies. This proposal details the develop ...

ABSTRACT: We propose to apply modern massively multicore processors to a key problem area of interest to the Air Force: multiphysics computational fluid dynamics (CFD) and computational structural dynamics (CSD) solvers. The capabilities of the CPU to solve these problems have been increasing steadily, but the CPU is still a general-purpose device designed to run diverse applications such as word ...

The proposed effort will utilize lithiated POSS in synergistic combination with commercial phosphates to achieve comparable processing characteristics and superior flame retardancy, smoke and toxicity to that of Derakane 510A. The POSS-phosphate synergist package will be formulated into a Hydrex nonhalogenated vinylester resin and superior mechanical properties (interlaminar shear strength and car ...

High efficiency, low pollution, and long lifetime make hydrogen-powered fuel cells desirable for portable power generation by the Army. However, it is impractical to transport hydrogen to where it is needed. Instead, reforming a transportable liquid fuel such as JP-8 or diesel fuel can produce the hydrogen for the fuel cell. Noble metal catalysts can speed this reforming, but they are expensive an ...

ABSTRACT: Crystalline semiconductor nanomembranes (NMs) possess the electronic/photonic properties of bulk material, although they are flexible, deformable, and conformable. Semiconductor nanomembranes offer unique opportunities for novel active/ passive electronic, and photonic devices suitable for vertically stacked high-density photonic/electronic integration. Silicon-on-insulator substrates. ...

The ultimate objective of the work outlined in this proposal is to develop, demonstrate and commercialize a new technology for accurate, rapid, low-cost tooling for discreet parts manufacturing of high-performance composite components. This tooling results from a new tool-production process and is suitable for prototyping, repair,

Hyperspectral imaging systems acquire the spatial and spectral information of the image scene simultaneously, and thus find important applications in remote sensing, military surveillance, and target identification. Most contemporary hyperspectral imaging systems operate at UV/VIS/NIR (ultra violet/visible/near infrared) spectrums. However, in many cases, especially in military applications, (hype ...

The WASP-III Advanced Reconnaissance Device Network (WARDN) is a miniaturized VHF/UHF emitter geolocation system targeted for installation on micro-UAV platforms. The Mav6 design approach of embedded antenna design, compact RF circuit design, and load balancing the signal processing and geolocation tasks between the airborne payload and the ground unit enables significant size, weight, and power ...

As an alternative to double-base propellants we propose electric solid propellants (ESP) as a safe, green, higher performance alternative to double-base propellants for high velocity electro thermal chemical (ETC) canons. These new energetic materials are inherently safe, with ignition only possible via the sustained supply of electrical power and not by spark, flame or even bullet impact. A maj ...

To improve the predictive capabilities of solid rocket motor end-of-burn phenomena, two analysis tools will be further developed. An existing engineering tool will go through continued development and validation, while an existing solid rocket ballistics model, built and demonstrated within a commercial CFD platform, will be expanded to allow for conjugate heat transfer between the burning grain ...
