PROJECT SUMMARY End Stage Renal Disease (ESRD) affects more 750,000 individuals in the United States alone. Hemodialysis (HD) is a life-sustaining therapy for patients suffering from renal failure that requires blood to be withdrawn and cycled through a dialysis machine. This process requires repeated needle punctures and the consequent needle access to a surgically created vascular shunt. These s ...

CRYOGENIC HELIUM REFRIGERATORS AND LIQUIFIERS CONVENTIONALLYEMPLOY OIL LUBRICATED POSITIVE DISPLACEMENT COMPRESSORS AT THE WARM END AND FREQUENTLY USE PISTON TYPE EXPANSION ENGINES AT THE COLD END. THESE SYSTEMS REQUIRE EXTENSIVE AND VIGILANT MAINTENANCE TO CONTROL CONTAMINATION FROM LUBRICATING OIL AND ITS VOLATILE COMPONENTS MIGRATING TO THE COLD END. HENCE THE NEED FOR LOW MAINTENANCE COMPRESSO ...

For the U.S. Navy, Creare is developing a Compact Swaging Machine (CSM) to attach arresting gear Purchase Cable terminals on ship. Our CSM utilizes three innovative features to dramatically reduce the size and weight of the swaging machine to make it usable in a shipboard environment: (1) a high pressure hydraulic system which minimizes the actuator size, (2) an efficient swaging schedule which re ...

Under AFRL Contract FA8650-05-M-5214 Phase I, CFDRC has developed and demonstrated the foundation of a comprehensive code for modeling the Cold Hearth Melting (CHM) processing of Titanium alloys. The code includes effects that accurately predict the transient temperature distribution, flow patterns, skull shape, species evaporation, and particle fates in the hearth region for a given set of dynam ...

We propose to develop a Health and Environmental Risks Assessment Capability (HERAC) that will allow Air Force personnel and related contractors to develop actionable, scientifically based, health and environmental risks assessments of maintenance tasks upon aircraft and other weapons. Presently, no capability exists to effectively model and simulate the microscale (from 2 to 50 feet) transport an ...

High performance metals, ceramics, and hard coatings are used in military applications to enhance the performance of key systems needed by the warfighter. One of the most prevalent operations to remove material, achieve the desired surface finish, or enhance part quality is bulk and finish grinding. For typical cutting speeds, conventional synthetic or oil-based coolants are sufficient to remove ...

RESEARCH AND DEVELOPMENT WILL BE CARRIED OUT TO PROVIDE PROTOTYPE, ACTIVELY CONTROLLED GAS BEARINGS FOR PRECISION MOVEMENT IN INSTRUMENTS AND MACHINE TOOLS. THIS WILL DRAW UPON PRELIMINARY WORK ON (1) FABRICATION, (2) DYNAMIC ANALYSIS OF THE BEARING AND SUPPORTED MASS, (3) PIEZOELECTRIC VALVING AND PIEZOELECTRIC DISPLACEMENT OF THE BEARING SURFACE, AND (4) THE ADAPTATION OF A MICROPROCESSOR TO SER ...

Missile radomes are a critical piece of modern military technology. As part of the missile body they protect the front of the missile and allow radio frequency (RF) signals used for guidance to pass through. Radome development is an artful engineering exercise that requires knowledge of materials, structures and radio frequency design and the manufacturing process is often costly and time consumin ...

Seek to optimize end-to-end additive manufacturing process for W-Re (tungsten-rhenium alloy) using NASA's additive manufacturing standard, in order to develop a reliable, repeatable process that produces fully dense W-Re with optimum material properties.
