Currently, difficulties in modeling non-linear behavior and damage modes of carbon-carbon (C/C) composites beyond simplified in-plane models prevent accurate assessment of bending load and thermal stress effects in interlaminar directions where the stress limits can be significantly lower than in-plane stress limits. To this end, the proposed Phase I SBIR program seeks to develop and refine a new ...

Current state-of-the-art biaxially oriented polypropylene (BOPP) polymer film capacitors exhibit excellent room temperature performance, but show significant deterioration in properties above 85 C. In Phase I, poly(vinylidene fluoride) (PVDF) and polycarbonate (PC) multilayer films were found to demonstrate excellent room temperature and high temperature performance. The viability of the technolog ...

ABSTRACT: The current F-35 repair CONOPS associated with any significant coating or structural damage requires the use of a trace and transfer approach to capture structural damage location, size and orientation. This is a cumbersome, time-consuming process that involves tracing damage on a large, clear piece of Mylar that is sent to Lockheed Martin (LM) engineers who"eye-ball"a mapping onto 3D m ...

ABSTRACT: Advances in nanotechnology have promised improvements in a variety of energetic materials; however, practical application of the technology has not matched its promise. One area of particular interest is in producing core-shell energetic materials based on metal (fuel)/metal oxide (oxidizer) chemistry that demonstrate thermite-like reactions. Cornerstone Research Group Inc. (CRG) propos ...

ABSTRACT: Specialized aircraft coatings can degrade over time and impact desired performance. Current reflectometers measure at normal incidence to the surface which does not accurately predict the electrical performance of the material across the aircraft's surface. It is desirable to measure the interaction of the non-specular component or traveling wave to fully characterize the electrical pe ...

ABSTRACT: UES proposes to develop a thermal model for additive manufacturing by electron beam melting that will enable selection of machine process parameters to maximize first part yield for arbitrarily shaped parts, and provide documentation to support rapid part qualification. The research will address manufacturing with Ti 6Al 4V and with Ti 6Al 2Sn 4Zr 2Mo using powder sources from different ...

ABSTRACT:There are numerous military applications where incorporation of Anti-Jam (AJ) GPS technology has been constrained by Size Weight and Power (SWaP), including handheld systems, unmanned aerial or ground vehicles, and munitions/weapons.The essential elements for incorporating AJ capability into GPS receivers are multi-channel RF front end down conversion, analog to digital conversion (ADC), ...

ABSTRACT:Advanced electrical loads, such as 270Vdc flight actuators, on high performance military aircraft are of special interest due to the near instantaneous demand and regenerative transients placed on the power system, including the generation components.Recent research has focused on designing/fabricating electrical accumulator units (EAU) to offload the transient loads from the generator to ...

ABSTRACT: The objective of this effort is to demonstrate innovative methods for deriving a sparse set of physical target features that can be used for exploitation of air-to-ground signature data collected from sensor systems including electro-optical, infrared, ladar, and radar. Current classification methods require near exact replication of the original imaging parameters, or extensive modelin ...

Our team will investigate a multiscale modeling framework to predict the final microstructure of a dual phase Ti 6-4 component as a function of thermo-mechanical processing. The microstructure properties will vary locally throughout the part, and will include features such as grain size, phase volume fraction, morphology of grains and phases, and the data structure representations will be scalabl ...
