Acadia Optronics, LLC, in partnership with the University of Kansas, proposes to develop a hybrid reconfigurable Software-Defined-Radio (SDR) architecture in which plug-in, front-end, rf modules interface to powerful, reconfigurable processing hardware and software through high-throughput interconnects. The complexity of the plug-in modules may range from simple antennas, to complete communication ...

ACTA Incorporated and Sandia National Laboratories propose a seven month STTR Phase I project to demonstrate the feasibility of developing an automated simulation of aircraft structural joints in structural analysis models. The technical approach includes an expert system executive to create detailed models of abstracted joint components including interfacing structural components, fasteners and ...

The present proposal is focused on developing novel methods to counteract excessive heat build-up in underwater sonar projectors. Building on over 25 years of experience in the design of Navy sonar devices and thermal management applied to high power density transducers and smart material actuators, Active Signal Technologies and Alfred University will model several readily implemented passive an ...

Software Defined Radio (SDR) technology and solutions are proven and capable. However, the cost of the systems limits their immediate use outside of military applications. Beside the cost of the SDR systems, it has been difficult to develop SDR concepts and prototypes on platforms that have clear migration paths to become commercial products. EFJI and Virginia Tech propose to develop a versati ...

Aluminum alloys are known to suffer from Stress Corrosion Cracking(SCC). SCC of high strength alloys can proceed rapidly, and can lead to devastating structural failures. However, a solid understanding of combined interactions of metallurgical, environmental and mechanical factors surrounding the crack tip during SCC is still elusive. Therefore, Al alloy developement for high corrosion resistance ...

Warfighters are increasingly relying on technology equipment to ensure safety, mission effectiveness, and situational awareness. This equipment increases the capabilities of warfighters but also adds to their weight burden. This excess load could cause significant stress on the musculoskeletal system and lead to physiological deficits. The overall objective of the proposed project is to develop a ...

The computational grid generation process remains a troublesome bottleneck in development of aerodynamic databases for complex geometries and multi-body configurations. The ability of Cartesian-grid based methods to perform automatic mesh generation and dynamic mesh adaptation allows for substantially reduced manpower, time and cost. The advantages of octree-based Cartesian-mesh methods have been ...

The primary objective of this program is the investigation of new approaches to achieve well-dispersed ultrahigh loading of carbon nanotubes (CNTs) in structural resins for advanced composites. “Well-dispersed” means CNTs that are optimally dispersed for achieving desired properties like strength, modulus, toughness, and thermal conductivity, rather than uniformly dispersed CNTs. Phase I will ...

Surface ship generated bubbles are a major signature contributor. For advanced ships such as the LCS, waterjet propulsion adds another source of air entrainment through the waterjet free surface interactions. In littoral warfare, such wakes provide an opportunity to wake homing torpedoes due to large acoustic cross-section of bubbles. While there is research on breaking waves bubbles, little is ...

A polarization insensitive wavelength converter is proposed to meet the stringent demands of avionic networks. Feasibility will be determined based on its ability to handle operation over large temperature ranges, and to provide Built in test functionality.
