Award Data

Manufacturing of structural composites traditionally employs autoclaves to achieve high quality parts, including high fiber-volume-fractions and low porosity. A laminate comprised of stacked prepreg plies are cured under a vacuum in addition to ~7 bar of pressure to prevent formation of voids, particulalry in interlaminar (inter-sheet/ply) regions. However, manufacturing composites within an autoc ...

Areas of research relating to self-healing composites structures have been undertaken by well-known and respected institutions under the auspices of the Department of Defense. Patent literature and public technical communiqué describe their novel engineering approaches using microencapsulated systems that release polymeric healing agents through suitable mechanisms. While these approaches have me ...

Physical Sciences Inc. (PSI) and their academic partner, West Virginia University (WVU), are pleased to propose a uniquely innovative approach to measuring the three-dimensional air wake velocity field behind ship structures and towers. The velocity data is needed to support the validation of CFD models that will ultimately be used to provide sufficient safety margins for ship aircraft operations ...

Green laser sources are important in advanced naval mine detection as this wavelength has good penetration though seawater. Mine detection programs such as the Coastal Battlefield Reconnaissance and Analysis (COBRA) system and the Airborne Laser Mine Detection System (ALMDS) currently use frequency-doubled 1-µm lasers as the laser source. The generation of green laser light via frequency doubling ...

SI2 Technologies, Inc. (SI2) proposes an innovative solution to the Navy’s need for wideband antennas to support naval ships and Marine Corps’ vehicle communications, electronic warfare (EW), and radar functions. SI2 will develop efficient, broadband, metamaterial antennas for operation in the VHF-UHF frequency range. These antennas will initially be designed for integration with the composite ...

The proposed work seeks to clearly demonstrate the advantage of the multiple-input multiple-output (MIMO) radar architecture over a similar single-input multiple-output (SIMO) or phased array system; the benefit of applying data-adaptive signal processing techniques in favor of their data-independent counterparts; and the utility of transmitting advanced probing waveforms as opposed to conventiona ...

The US Navy recognizes the potential for “big data” to facilitate force readiness. However, the analysis of such data presents numerous challenges, among them, (1) the evolving nature of Navy tactics, hindering apples-to-apples comparisons; (2) the presence of many interdependent platforms, making data complex; and (3) presenting analyses to humans, making understandability important. Aptima� ...

Vertically-aligned carbon nanotubes (VACNTs) will be selectively applied at interfaces in laminated composite structures to effect locally the mechanical properties that limit rotorcraft structures, such as fatigue and damage tolerance. In Phase I this work will quantify these effects in CFRP and CFRP/GFRP hybrid coupons. The VACNT material will be transferred directly onto prepreg plies, but also ...

The exponential growth of text-based communication associated with the Internet has lead to a vast increase in the amount of unstructured messages that open source intelligence needs to process. This increase has lead to the need to develop methods for facilitating the detection of deception in various forms of text-based messages, from chat rooms, emails, weblogs, to text messaging. Methods are r ...
