Military shelters currently use electrically driven Environmental Control Units (ECUs) to provide cooling for the air inside the shelter. The ECU is vapor compression cycle powered by a diesel generator, operating on JP-8 fuel. Other than fueling jet engines, the largest drain on U.S. military fuel supplies in current operations comes from running generators at forward operating bases. In hot cli ...

A clean-slate approach is needed for the design and implementation of wireless networks that self organize and can scale with the number of users, devices, and information objects and services that network users wish to share. This project will develop a new architecture and protocols for wireless networks in which naming, addressing, routing, and channel access are redefined to take into account: ...

Synthetic scenario-based training of Navy personnel in the use of Navy SIGINT/IO systems has helped to reduce training costs, and it has enabled the personnel to be trained in an environment that sufficiently approximates real-world situations that could not otherwise be accomplished within the class room. However, scenario development is highly complex and involves a great deal of human effo ...

The SOLUTE team’s Phase I technical approach consists primarily of a feasibility study assessing the viability of a Navy implementation of the algorithms, standards, and protocols that comprise Google's Wave technology. Of specific concern is Wave’s ability to handle varying bandwidth and DIL communications channels associated with Navy platforms. While computer science research in the field o ...

In today’s information age, there are vast resources of data on every region of the Earth. The application of geospecific imagery over large areas has been limited to terrain for the most part. The hindrances to full use of geospecific imagery are the labor required to create the databases, and limits on the rendering capacity of current image generators (IGs), both in polygon count and texture ...

A software tool for fracture evaluation and load deflection prediction of welded aluminum ship structures subjected to impulsive loading will be developed by enhancing and integrating an existing extended finite element method (XFEM) for dynamic fracture of thin shells in Abaqus. The software package will be able to model arbitrary crack paths as dictated by the physics of the scenario, completely ...

A rapid prototyping simulation for the Autonomous Rotorcraft Land & Take-Off (ARLTO) system will be developed to analyze and evolve requirements for the landing and take-off of a Rotary-wing Autonomous Air Vehicle (RAAV) from unprepared terrain. The simulation is based upon the Task-Pilot-Vehicle modeling system and features a UH-60 configured with a Sliding Mode Control (SCM) inner loop closure. ...

In miniature gas turbines for UAV applications, traditional bearings exhibit a typical lifetime of only 25 hours due to excessive axial loading. Mainstream proposes to use a passive, permanent magnet thrust bearing to alleviate this problem and increase service life to over 1000 hours. Since this type of bearing is non-contacting, it can operate at very high rotational speeds with minimal heat gen ...

The Navy has need of assessing the river environment including bathymetry, flow velocity profile, and navigational obstructions. While improvements in measurement fidelity and reduction in cost have come about by the use of multiple drifters, measurement quality is lost due to convergent drifter trajectories, and cost/risk remains high due to personnel effort required for deployment. An autonomous ...

We propose to build an emitter localization and detection system that can geolocate signals in the 800-2400 MHz range. The system can be rapidly-deployed, provide accurate emitter locations, deals with many-emitter problem explicitly, and can find low-power emitters.
