An innovative concept for a scalable Digital Beamformer that can be applied to the full range of Navy radars/RF communication is proposed. The concept is photonics based and will support transmit/receive applications over the 0.1 to 40 GHz, and V bands. The design provides a digitally controlled True Time Delay based Beamformer effectively adaptive to a phased array in any portion of the spectral ...

This proposal aims at the development of a low-power deicing system using the newly developed magnetostrictive alloy as functional materials, namely the Ni-Mn-Ga alloy. Present studies have shown that the Ni-Mn-Ga smart alloy does not require excessive input power to operate while an impulsive strain of over 5% can be generated under a load of over 1 Mpa. When power is applied to the solenoid arou ...

Advances in modeling and simulation, networking, and computer graphics technology have made it possible to conduct large-scale, distributed LVC training events, such as the Navy’s Fleet Synthetic Training-Joint (FST-J) exercises on a regular basis. However, FST-J exercises are not without room for improvement. Instructors and exercise controllers often confront difficulties assessing the state ...

Vertical short takeoff and landing (VSTOL) operators face numerous challenges, particularly during takeoff, hover, and landing operations. Threats take the form of power lines, structures, and—in the case of combat—enemy fire. Often, these threats are obscured when visibility is compromised by dust, sand, or snow. Maintaining awareness of the surrounding environment becomes almost impossible. ...

GhostSwimmer is a tactical, efficient, biomimetic autonomous artificial fish UUV that employs the actual mechanics and dynamics of biological fish to create the ultimate in efficient swimming while remaining responsive to the needs of current covert, riverine, and littoral missions. It endeavors to attack problems facing current UUVs. A product of the combined experience of David Barrett (Olin Col ...

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 ...

Despite their utility, VSTOL aircraft have been plagued by high accident rates, leading to unacceptable safety risks and extensive equipment maintenance costs. To enhance VSTOL safety, particularly under instrument flight or degraded visual conditions, we will design, demonstrate, and evaluate novel visual Displays for Ecological VSTOL Operation (DEVO). These displays—the first application of ec ...

To help training managers process the diverse and high-volume streams of information from LVC training exercises and control the entities within those exercises, we propose to design and demonstrate a system for Integrated Visualization and Control for Live, Virtual, and Constructive Training Management (IVAC-4-LVAC). Our solution is comprised of three key elements: 1) Advanced visualizations of c ...

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 ...
