Scrub typhus, caused by Orientia tsutsugamushi poses a threat to U.S. forces deployed to the Asian/Australian/Pacific regions during contingency and peacekeeping operations. Development of an assay for the detection of O. tsutsugamushi that is rapid, accurate, field-usable and soldier-friendly is therefore a high priority for the DoD. In its Phase I effort, Access Bio demonstrated the feasibili ...

Development of three Bipropellant Tank designs with mechanically linked pistons for Advanced Small Missile Systems. The study will consider the technical and fabrication issues associated with the design, and rate the comparative merits leading to the selection of Phase II continuation.

The objective of the proposed research is to develop new technologies based on principles of Time Reversal Acoustics (TRA) that will provide highly sensitive land mine detection. We suggest applying the Time Reversal Acousto-seismic method in combination with a nonlinear acousto-seismic mine detection technique. The TRA focused system provides a high concentration of seismic wave energy at any des ...

The objective of this proposal is to develop a Muscle Water Content (MWC) sensor, an ultrasonic device for assessment of body hydration status in soldiers with accuracy better than 2% during deployment and training. The MWC assessment is based on measurement of ultrasound velocity in muscle, which is, to a good approximation, a linear function of the water content. The expected outcome will be ...

This proposal develops an extremely low cost fiber grating corrosion sensor system that could be deployed on a vehicle. Costs are estimated to be approximately $0.25 per sensor in volume allowing hundreds to be deployed if necessary on difficult to access areas of a ground vehicle. In order to keep costs to an absolute minimum it is anitipated that the read out unit would be maintenance rather t ...

The Phase II program proposed here represents a novel approach to provide a PC-based tool for the design and evaluation of Visual Landing Aids (VLAs) in supporting Naval aviation launch and recovery operations. The software is based on the use of a suite of tools built around Virtual Reality Modeling Language (VRML) and X3D constructs. VRML and X3D are open 3D graphics standards supported by sev ...

In Phase I, a demonstration SUpersonic Rain Erosion (SURE) facility was developed which demonstrated the capability of producing spherical, millimeter-sized droplets repeatedly at velocities up to 1200 feet per second. Data were collected to extend the speed range of the facility and droplet size. Based on these results, a Phase II prototype facility will be built that could attain speeds of 240 ...

Current Navy simulations for representing Dynamic Interface (DI) operations are often restricted to include only one aircraft interacting with a ship airwake structure. Phase I work identified extensions to Continuum Dynamics, Inc.'s CHARM module for computing free vortex wake structures from rotorcraft that permit multiple aircraft interactional aerodynamic effects to be modeled simultaneously. ...

Accurate performance prediction is crucial to the simulation, analysis and flight testing support of rotorcraft. In this regard, current analysis tools inadequately model key phenomena like blade dynamic stall, rotor tip loads, and rotor downwash because of their failure to predict the true unsteady three-dimensional nature of the aerodynamic environment near the rotor. Continuum Dynamics, Inc. ...

The D.N. American research and development team proposes a novel approach to improving the process of multidisciplinary optimization for composite laminate designs. In Phase I, we successfully demonstrated the feasibility of our approach to the problem. The Phase II effort leverages these results along with the team's experience-in design optimization with Genetic Algorithms, composite laminate ...
