UAV operations in known icing conditions present a problem whose solution critically depends upon their flight testing in artificial icing environments. Unfortunately, instrumentation, control, and operational procedures have yet to be developed to support this testing behind manned aircraft, such as the U.S. Army CH-47 Helicopter Icing Spray System (HISS), that may produce the artificial icing c ...

Fuel cell power sources offer numerous benefits over conventional power sources like diesel engines for deployment at forward operating bases, silent watch and other applications important to the armed forces. However, the major technical challenge in the implementation of PEM fuel cells is a suitable hydrogen source. For these applications fuel processors based on hydrolysis of chemical hydride ...

Mercury Cadmium Telluride, HgCdTe (MCT), is the most important material for modern infrared detectors and imaging arrays for wavelengths of strategic and tactical interest. Current substrates for HgCdTe detector deposition remain limited by high cost and severely limited available areas (CdZnTe bulk crystals), or by unacceptably large defect densities due to large material and thermal mismatch (Si ...

The objective of the this phase 1 proposal is to design and develop an access control policy framework that is a scaleable across the Army enterprise by allowing for the decentralized management and local enforcement of the access control policies, minimize impact on the network with respect to policy traffic, allow for interoperability between Community of Interests (COIs) or domains and allow fo ...

The objective of this project is to develop a test-validated CAD tool for performing virtual laser shock peening(LSP) simulations of rotorcraft components. Virtual LSP peening can be used, in conjunction with virtual fatigue testing, to conduct simulations to assess the effects of variations in process parameters, i.e., laser beam power density and size, number of layers, and the overlay pattern ...

The purpose of this proposed research is to develop a rapid field test system for detection of hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS) infection in humans and rodents using a lateral-flow immunoassay. This assay will have a broad technical impact in that it can be used in animal laboratories interested in ascertaining if their mice or rats have hantavir ...

RFID tags and a wireless infrastructure for tag communication has become a key technology for providing In-Transit Visibility of the DOD logistics pipeline, and is critical technology for providing effective logistical support to DOD forces in operational theaters. This technology consists of battery powered data rich (128k) RFID tags operating at unlicensed short range (300-600 feet) commercial f ...

Accurate rotorcraft performance prediction is essential to both the design and development of rotorcraft, and also the support of flight testing, establishing of safe flight envelopes and analysis of flight operations. While current Lagrangian- and Eulerian-based analysis tools can, in principle, model the complete rotorcraft, in practice these implementations are severely hampered by accuracy li ...

The effectiveness of training personnel in immersive 3D virtual environments is currently limited by control interfaces that require users to perform actions, for example moving a joystick or pressing a button, that are not present in equivalent real world tasks and situations. In Phase I of the project soVoz will determine the feasibility of developing advanced man/machine Virtual Control System ...

The US Army helicopter fleet consists of upgraded helicopters that were originally designed in the 70's and 80's. The more electric aircraft philosophy has put a strain on electrical systems, and has exhausted their growth potential. Replacing the generator on an existing engine/gearbox poses a challenge because of weight, overhung moment, and space limits. Therefore, most likely the only solution ...
