At present, the predictive capability of simulation codes and models used in the conceptual planning and design of high-speed propulsion systems is limited by the ability to describe the complex flow fields inside the combustor, mixing models, detailed chemistry and turbulence-chemistry interactions, and subgrid-closure models. The objective of the proposed work is to develop and validate a high-f ...

ABSTRACT: This Phase I STTR project will develop carbon fiber reinforced polymer (CFRP) material systems incorporating metallic nanoparticles with low-temperature sintering properties to render structures with very high transverse thermal conductivity. CFRPs are already used in a myriad of applications requiring high strength-to-weight ratio, but their poor transverse thermal conductivity limits ...

ABSTRACT: We present a novel architecture for on-demand clouds, which means creating a cloud computing environment when needed that opportunistically takes advantage of available processors. The processors are located on mobile computers at the tactical edge of a network and connect via wireless networks. Clusters of processors can be interconnected by trunks. Compute nodes may appear or disappea ...

ABSTRACT: MicroLink proposes a device that combines ultra-thin, high-efficiency, GaAs-based multijunction solar cells, made using our proprietary epitaxial lift-off (ELO) process, with a novel packaging approach that will result in high-efficiency, flexible photovoltaic blankets. MicroLink has developed a process that produces ultra-thin, flexible solar cells. In this project, these flexible so ...

ABSTRACT: Photosensitive protean materials form essentially a new class of materials which are manufactured in one state but its select material properties can be physically and locally altered through patterning and lithography. In this proposed research, we will demonstrate the feasibility of creation of conductive copper lines imbued in the glass by using novel glasses with laser direct writin ...

ABSTRACT: In this STTR effort a small business company Obalon LLC is teaming up with industry leader Aerospace Corporation in order to develop novel photostructural glass ceramic composition PhotoCon with capability of laser induced 3D conductor patterning inside the bulk material. Following the photolytic process of laser exposure and the development of latent image the team will implement the s ...

ABSTRACT: In order to significantly advance the fidelity and capability of current computational engineering tools, algorithms, techniques, and software which map effectively to emerging massively parallel hardware architectures must be developed. The objective of this project is to investigate and demonstrate specific techniques for enhancing the scalability of computational fluid dynamics (CFD) ...

ABSTRACT: The purpose of the proposed Air Force Phase I STTR program is to fabricate semiconductor nanomembrane based photovoltaic (PV) power sources on flexible substrates, using Virginia Tech NanoCMOS Laboratory"s SOI silicon nanomembrane technique in combination with NanoSonic"s pioneering Polynanoguard antireflection copolymer nanocomposite materials, which afford high levels of antireflectio ...

ABSTRACT: With the current flood of surveillance data available to ISR analysts, human attention has become the most valuable resource to ISR systems. Although automated tracking and labeling algorithms are now capable of automatically identifying and roughly classifying targets, the current rate of false alarms and irrelevant annotations makes existing technology unsuitable for wide-area persist ...

ABSTRACT: Advanced computational methods and increased computing power have brought about a new age of modeling and simulation capability for full aircraft configurations. These advances have provided the potential ability to conduct accurate computational analysis representative of experimental flight testing, reducing both risk and cost. A unified toolset to conduct a complete end-to-end virtua ...
