The Navys Next Generation Integrated Power Systems (NGIPS) for on shore, surface ships, and underwater vehicles will require novel power distribution systems. State of the art prime mover power generation and high power directed weapons require power distribution cables that surpass conventional copper cable capabilities. As such, the Navy has determined that electrical power systems must increase ...

Future power systems on board Navy ships require electrical power in the order of 20 to 80 MW, which currently cant be provided by conventional copper or aluminum power cables. Advanced Conductor Technologies LLC (ACT) has been developing high-temperature superconducting Conductor on Round Core (CORC) power transmission cables, rated at 10 kA per phase, for the Navy that form a potential solution ...

The main focus of this research will be to develop effective modeling toolboxes to analyze CM current/voltage behaviors and fault conditions at any part of the power system in a cost and time effective way. The toolbox will assist with grounding strategies and enhance the baseline design. A CM equivalent circuit model [3] has been developed to analyze the CM current/voltage behaviors. In this work ...

Using a fluid dynamic energy separation technique, in combination with thermoelectric generators (TEGs), a unique hybrid cooling system using low grade waste heat is proposed. This system uses the concept of fluid structure interactions and vorticity redistribution to produce large levels of vorticity within working fluid and thereby generate large temperature gradients in the working fluid which ...

As Navy combat systems evolve, the heat loads produced by electronics enclosures continues to increase. Legacy thermal management techniques for these enclosures such as liquid cooling coupled to the ship chilled water supply and direct air cooling of the cabinets require infrastructure such as pipes and ducts which are expensive to install and reconfigure. Mainstream proposes to design a vapor co ...

DeepDive is a system for extracting relational databases from dark data: the mass of text, tables, and images that are widely collected and stored but which cannot be exploited by standard relational tools. If the information in dark data --- scientific papers, Web classified ads, customer service notes, and so on --- were instead in a relational database, it would give analysts access to a massiv ...

Systems that operate in constrained environments depend on the acoustics in several ways. Harbor defense systems detect intruders (people and/or vessels) by either listening for their noises (passively) or by pinging on them and detecting their echoes (actively). Furthermore, such systems may also form the equivalent of an underwater cell phone network using sound to carry the information. The aco ...

The Navy seeks new energetic and oxidizing ingredients for use in propellant and explosive formulations of modern weapons systems. With recent developments in the design and synthesis of new energetic molecules, we have the opportunity to take the steps needed before these materials can successfully transition to use in next generation propulsion and ordnance systems. TDA Research and the Universi ...

We are proposing to identify an ICME architecture that will enable the multi-scale modeling of additive manufacturing (AM) process at both the component level as well as at the meso-scale level such that the final part quality and performance can be predicted accurately. At the component level, the proposed ICME framework would help in predicting residual stresses, distortion and the necessary sup ...

High power, high voltage switching via semiconductor materials is attractive from a size, weight, and profile perspective. The Baliga figure of merit for high voltage for Ga2O3 is 3,415 (relative to Si), which suggests this material is well-suited for power device applications. Kyma Technologies proposes to design a deposition system capable of growing monoclinic beta-polytype Ga2O3, and n-type an ...
