Although biodiesels have been increasingly used in automobiles, trains, commercial aircrafts and heating systems, they are not currently used in the military aircrafts and land vehicles because they typically do not meet the JP-8 performance criteria as specified by MIL-PRF-83133E. Unintentional contaminations by the biodiesels into the jet fuels can introduce adverse effects, including engine ope ...

Upgrades to the Bradley and Stryker vehicles and concepts for a next-generation ground combat vehicle require substantial expansion of the electrical power generation and distribution system. The upgrades must be implemented within very tight spaces, and this requires technology advances such as higher operating temperature and power density and increased interoperability within the vehicle. Cre ...

IN THE PROPOSED RESEARCH THE FEASABILITY WILL BE ESTABLISHEDFOR DEVELOPING A LOW-COST EXPENDABLE TRANSDUCER MOUNTED IN ANATIONAL WEATHER SERVICE TYPE RADIOSONDE TO MEASURE VERTICALPROFILES OF SUPERCOOLED LIQUID WATER. THE TRANSDUCER IS BASED UPON A WIRE WHOSE NATURAL VIBRATION FREQUENCY VARIES ACCORDING TO THE AMOUNT OF ICE COLLECTED ON THE WIRE. THE RESEARCH WILL EXAMINE THE EFFECTS ON THE THE RE ...

Tantalum alloy and silicon nitride gun barrel liners have demonstrated excellent corrosion resistance and wear characteristics for U.S. Army applications. The quality and accuracy of the rifling profile is critical; however, the processes and tooling needed to successfully rifle a gun barrel made from these advanced materials have not been developed due to the difficulty of machining the material ...

Small manned and unmanned aircraft need advanced propulsion technology to increase mission capabilities and improve reliability. We propose to develop an innovative recuperator technology that can significantly reduce fuel consumption for small gas turbines. Our microchannel recuperators are built using advanced manufacturing techniques that will enable a compact, inexpensive recuperator to signif ...

HEAT EXCHANGE MATRIX THE FUNCTION OF A HEAT EXCHANGER IS DEPENDENT UPON THE AREA OF EXPOSURE TO THE FLUIDS IN PROCESS. FINS ARE COMMONLY USED TO INCREASE EXTERNAL SURFACE AREAS. TO EXTEND THE INNER SURFACE OF A TUBE OR VESSEL IS MORE DIFFICULT AND THERE IS CURRENTLY NO COST EFFECTIVE METHOD TO DO SO. THIS REDEARCH IS TO DEVELOP THE USE OF A MATRIX COMPOSED OF SMALL, HOLLOW, METAL CYLINDERS, BRAZED ...

Providing power for dismounted soldiers on long-duration missions remains a critical technical challenge. Polymer electrolyte membrane (PEM) fuel cells convert hydrogen fuel directly to electric power and offer a lightweight and efficient power source for individual soldiers. However, technology for storing the hydrogen fuel is still too heavy to meet the Armys mission requirements. We propose to ...

A SIX MONTH PROGRAM TO DEVELOP A RUGGED NEW DEVICE FOR MONITORING THE ONSET OF ICE FORMATION ON SURFACES OF TRANSPORTATION VEHICLES, ROADS, BRIDGES AND AIRCRAFTS, WILL BE DEVELOPED AND A PROTOTYPE WILL BE LABORATORY TESTED. THE NOVEL GAGE AND ELECTRONIC SYSTEM IS PARTLY BASED ON THE TECHNOLOGY APPLIED TO MEASURE CONDUCTIVITY OF SOLUTIONS. BASED ON EXISTING TECHNOLOGY, AND ALREADY TESTED UNDER HIGH ...

The Army uses Unattended Ground Sensors (UGS) for the location and tracking of enemy soldiers and vehicles. The sensors can often determine range and relative bearing to the signal source, but without knowing its own orientation, these data cannot be converted to source geo location and ground track. There is therefore a need for a sensor to determine the UGS azimuth, roll, and pitch relative to a ...
