Increasingly stringent exhaust emissions and fuel economy legislation is forcing automotive engine designers to: 1) demand increased pressure ratios from turbocharger compressors to ensure complete fuel combustion, 2) use Exhaust Gas Recirculation for emission reduction, and 3) reduce engine displacement while maintaining or even increasing output power to reduce fuel consumption. These three chan ...

The technology development for the supercritical CO2 (sCO2) power plant is well underway, and the first pilot plants are now under construction. The new pilot plants are sized for a 10 MW net power output; a good size to gain valuable data for larger utility scale power plants. This is also a very good size for the smaller, distributed power applications. The distributed power application is envis ...

A novel integrated inter-propellant seal and thrust bearing (IPS/TB) for rocket turbopump applications that uses the latest technology developments in seal coatings and additive manufacturing to advance the state-of-the-art. The IPS/TB has low propellant loss, requires little or no purge gas, and no continuous purge when the turbopump is not in operation. The thrust bearing portion can handle all ...

ABSTRACT:Tactical Air Control Parties (TACP) and Joint Terminal Air Controller (JTAC) deploy with not only a significant amount of gear, but also a large work load in order to manage all of their responsibilities. As the battlefield becomes more digitized, it is forcing TACPs/JTACs (which we will refer to as just TACPs for brevity in the document) to deal with more information than their current s ...

Many contaminated DOE sites are located in arid regions where depth to groundwater is significant and/or contaminants were discharged into a vadose zone through which transport to the groundwater table is dominated by unsteady, unsaturated groundwater flow. The absence of an effective means to monitor vadose zone moisture content in profile has been a persistent impediment to developing and calibr ...

Increased use of Exhaust Gas Recirculation (EGR) combined with engine downsizing has pushed automotive turbocharger compressor operation towards and often beyond its efficient and stable operating boundaries. Much of the drive cycle is spent operating the compressor at low flow rates and low pressure ratios, near the compressor surge line, in an area which is usually of low efficiency. Our prelimi ...

Appareo Systems, LLC, proposes to develop a functional prototype head-mounted position and orientation system (HPOS). The HPOS will be capable of operating in electromagnetic fields of up to 200 volts/meter and will provide at least one degree of accuracy and at least one degree of resolution at a 60 Hz update rate while providing 3 degree of freedom (DOF) information on head orientation, includi ...

Hybrid Electric Vehicles (HEVs) and plug-in Hybrid Vehicles (PHEVs) require advanced technology capacitors, which must have low cost and the ability to operate at 150oC. However, current 150oC film capacitor solutions are expensive and have lower energy density compared to materials that operate at lower temperatures. Polypropylene Film Capacitors represent a potentially cost effective solution ...

Historically, remediation efforts at DOE contaminated sites have relied on numerical models to integrate laboratory and field characterization data, predict the fate and transport behavior of contaminant plumes, design remediation protocols to mitigate contaminant migration, and analyze data from field remediation results. Of particular concern is the effect of subsurface heterogeneities and thei ...

Standoff detectors are required to detect IEDs. These detectectors are needed to save the lives of American soldiers. QuantaSpec has developed patent pending methods for long-range, sensitive, and selective standoff detection of explosives. These methods have already demonstrated sensitive remote detection of explosive vapors under previous efforts. QuantaSpec's multidisciplinary team will dem ...
