This Small Business Innovative Research Phase I project will develop an innovative High Velocity Particle Consolidation system using liquid particle acceleration mechanisms for Cold Spray applications. Conventional Cold Spray uses high pressure process gas to accelerate particles to a critical velocity, so that upon impact with a substrate, the particles plastically deform and create a coating. ...

The objectives of this proposal are to develop an animal surrogate finite element (FE) model and environment that can be used as a tool to investigate injury mechanisms and mitigation of traumatic brain injury (TBI) due to blast overpressure. A rat head model with a high degree of anatomical detail will be refined for used within an FE blast environment. To avoid the use of unnecessarily costly ...

Rollovers result in significant civilian and military injuries and fatalities. Four technical gaps were identified in Phase I: lack of biomechanical data for rollover dummy design, numerous rollover test conditions needed to understand occupant kinematics

With the advent of widely available PC technology, crash safety information can be cost-effectively disseminated to millions of people in an engaging and educational way. With an enticing and informative PC application, data about damages, costs, injuries and death can be personalized and grasped by anyone, particularily young drivers developing new driving behaviors. ARCCA's proposed system wil ...

The Baker Single Cylinder Opposed-piston Engine is a 24 cu.in., 30 Hp engine with high power density (0.642 Hp/lb or 35.7 Hp/cu.ft.) capable of running on multiple fuels. The engine concept offers a totally new look at small engine development while utilizing several conventional engine components. In addition to high power density, the engine has significant advantages over current small engine ...

WE PROPOSE TO DEVELOP AND VERIFY IN THIS PHASE I PROGRAM A TECHNIQUE THAT WILL ACCURATELY AND REPEATABLY MEASURE SURFACE PROFILES AND DISTANCES BETWEEN A TEST OBJECT AND DETECTORS USING THE SHEARING HETERODYNE INTERFEROMETRY TECHNIQUE. THE TECHNIQUE IS BASED ON SHEARING HETERODYNE INTERFEROMETRY WITH A FREQUENCY MODULATED LASER DIODE USING THE FOUR-BUCKET-INTEGRATING TECHNIQUE. IT CAN BE USED TO D ...

While the efficiency of x-ray sources is defined by the laws of physics, present day sources do not take full advantage of those laws. Other materials thant tungsten are not only more efficient in producing bremsstrahlung, but have "characteristic" x-rays that can make the beam harder instead of softer (as in the case for tungsten). Today's tubes also do not use optimum angles for the incident e ...

We propose to study development of a wireless network of seismic/acoustic/GPS sensors to carry out the ordnance-impact characterization. We propose to modify an existing design that includes a three-componenent seismograph (sampled at 10kHz), a microphone, and a high-precision GPS receiver. These data are optimally subsampled and wirelessly transmitted over an 802.15 ("zigbee"-like) Personal Are ...
