Maintaining accurate position location information (PLI) during operational missions is a critical requirement for the dismounted soldier. This requirement is unmet in heavily forested and jungle environments where GPS reception is unavailable due to dense canopy cover. In such environments, soldiers must determine their location by using visual landmarks, or by seeking open clearings where Global ...

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 ...

TECHNICAL ABSTRACT: Commercially available unmanned aircraft systems (UASs) are not well designed to meet requirements for many atmospheric measurement applications, including deployment from ships, long endurance, and low cost. Existing multi-rotor systems suffer from limited payload and endurance. Existing fixed wing systems offer improved endurance and payload, but require significant support h ...

PROJECT SUMMARY ABSTRACTMillions of children around the globe are afflicted with conditions that can alter neuropsychological developmentincluding human immunodeficiency virusHIVtraumatic brain injuryTBIcerebral malariaand a host of other developmental and acquired diseases and disordersEarly assessment and intervention are critical in overcoming cognitive and developmental deficiencies and are in ...

Arctic Slope Technical Services, Inc. (ASTS) is pleased to propose to continue the development of an additive manufacturing (AM) approach for fabricating bimetallic combustion chambers. Our chamber design, which is applicable to future NASA small launch vehicles, exploits the combined capabilities of selective laser melting (SLM) and magnetic pulse welding (MPW), in order to reduce manufacturing ...

Tungsten and its alloys are candidates for plasma facing component (PFC) armor due to their low sputtering rate, high melting point, high thermal conductivity, high strength at elevated temperatures, and low tritium inventory. Although copper alloys have been selected for the heat sinks for ITER, a working fusion reactor will require the use of higher strength, low activation materials. For exampl ...

Mountain descent test procedures that replicate conditions found in severe mountain environments are essential in identifying the limitations of current and future vehicle systems. Current tests have failed to reproduce these severe, realistic conditions resulting in deficiencies in overall vehicle performance. In Phase I a prototype Brake Fade Advance Warning System (BFAWS) and mountain descent r ...

Improved head and hearing protection is required for aircraft maintainers working on a carrier flight deck during launch and recovery operations. Legacy Flight Deck Cranials are inadequate in many aspects including hearing protection and impact protection. In previous work, Creare has developed a Flight Deck Cranial (FDC) that offers unparalleled hearing protection and industrial standard head pro ...

FreEnt Technologies, Inc. (FreEnt) and Johns Hopkins Universitys Applied Physics Laboratory (APL) are proposing a multiple-hit detection sensor called the Optical Lethality Measurement System (OLMS). This system is based on the Planar Optical Penetration Sensor (POPS) technology (originally developed and patented by APL) and prior art associated with the Blast Initiation Detector (BID). The BID is ...

In response to DLA SBIR Topic DLA152-001 for Advanced Manufacturing Technologies, Sentient Corporation (Sentient) proposes to develop a life cycle cost optimization tool based on our commercial DigitalClone modeling technology. This tool will enable users to evaluate the tradeoffs between alternate manufacturing processes, implementation costs, and the performance/durability of the resultant comp ...
