This proposal addresses the development and use of lightweight, low thermal-capacity reformable tooling materials for high-temperature composite processing evaluation, parts prototyping, trial production and full-rate production of PMC engine components. The weight-saving promise of high-temperature polymer matrix composites (PMCs) for engine components is offset by the very high costs of parts m ...

This project will investigate candidate space-time coding schemes to be incorporated in a multiple-input multiple output two-way communication system that operates within an urban warfare environment. The main objective is to increase channel capacity to achieve high-quality video transmission using narrow signal bandwidths, typically deployed for voice channels. The investigation will determine t ...

Nanofiber nonwoven spunbonded materials technology is adapted for use in a personnel lowering device. The resulting device will be simple, easy to use, and relatively low cost.

The addition of advanced power electronics, radar, armor and weapons systems will significantly increase the thermal load onboard the Navy’s future warships. Advanced Cooling Technologies, Inc. (ACT), supported by Alstom Power Conversion and American Competitiveness Institute (ACI), will develop a high performance oscillating flow heat spreader technology for cooling of high power electronics th ...

Advanced Cooling Technologies, Inc. (ACT), in partnership with the University of Nevada-Reno (UNR), is developing a high performance metal hydride heat storage and dissipation technology for high power lasers. The proposed technology incorporates heat pipes for passive acquisition and dissipation of high heat flux heat loads and metal hydrides for storage of the heat loads during the laser operati ...

A key component of the Navy fuel cell system is the reformer, which converts diesel fuel into methane for consumption by the fuel cell. Reaction temperatures are critical to proper function of the reformer. Reaction temperatures are currently regulated by valves in the process gas streams. These valves require power, consume space, increase pressure drop, and are hindering tight integration and pa ...

Advanced Cooling Technologies, Inc. (ACT), supported by Hamilton Sundstrand, proposes to develop a shock and vibration tolerant Capillary Two-Phase Loop for military vehicle applications. The proposed capillary two-phase loop differs from the traditional loop heat pipes and capillary pumped loops in the evaporator design, which provides inherent tolerance to shock and vibration. Two additional fea ...

The objective of this proposal is to demonstrate the feasibility of producing exchange-coupled magnets with a mixture of Sm2Fe17Nx and alpha double prime-iron nitride powders as starting materials. Advanced Materials Corporation (AMC), together with Georgia Institute of Technology propose to produce these powders with the use of a fluidized bed reactor and consolidate mixtures of these powders uti ...

In composites, not only can properties vary with load direction, fiber based composites also offer the unique ability to tailor material properties locally. Localized matrix or fiber architecture changes can meet local mechanical, electrical, or thermal loads within a component or vehicle, without weight penalty or resort to additional external structures. In Phase I, the team used 3TEX 3-D wea ...

During Phase I, 3TEX designed universal, one-piece, 3D woven fiber preforms which can be used as either a “Butt” (H) joint or as a “P” joint as needed. Composite joints were fabricated and tested, demonstrating the benefit of the integral nature of the 3D preforms. 3D stress/strain and crack propagation analysis of composite Π-joint was performed using 3D MOSAIC code. 3D displacement, st ...
