A critical operational problem for current Army rotorcraft is the prediction of landing conditions in a sand/dust/snow laden environment where rotorwash picks up loose ground cover leading to a condition of obscured visibility known as "brownout". The proposed effort will develop both a comprehensive analysis and flight simulation tool able to predict the magnitude and distribution of visibility ...

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 ...

MSI has conceived a novel wall penetration and behind-wall-activated munition in lethal and nonlethal varieties. The U.S. Army currently does not possess a compact, man-portable weapon specifically designed to breach structure walls and deliver a submunition of choice (lethal or nonlethal) to an enemy that is sheltered within the building's interior. The proposed project develops such a weapon i ...

Insensitive munitions (IM) design and testing for propulsion systems is hindered both by high test costs and the complexity of propellant responses to IM stimuli. Modeling and simulation tools for predictions of IM hazards are under development that characterize many of the pertinent phenomena, including damage sensitization to reaction and delayed-onset detonation. Such tools can provide many b ...

A novel and promising solution is proposed for a smart self-configuring miniature windscreen. The proposed solution includes a mechanical windscreen, MEMS microphones, and a DSP windscreen. The mechanical windscreen will be designed by numerical simulation. The finite-element method will be utilized to simulate the effect of different shapes of windscreens on the aerodynamics in the vicinity of th ...

A novel and promising solution for hands - and eyes-free voice interface for point-of-care data entry is proposed. The solution consists of the following major modules: a recently-developed noise-reduction microphone, a Bluetooth earphone, an automatic speech recognizer, a text-to-speech synthesizer, and a dialogue manager. To make the developed system useful in combat environments, we emphasize o ...

Currently, adequate ballistic protection in optically transparent surface shields and transparent armor is provided either by thick sections of polymers, or by laminated sheets of polymer and glass. In both cases, the areal density is very high. For reasons explained in the proposal, efforts to date on the synthesis of transparent polymer nanocomposite materials, especially those based on polycarb ...

A UNIQUE HIGH TEMPERATURE, HIGH PRESSURE GASEOUS PHOTOCHEMICAL REACTOR WITH OPTICAL AND MASS SPECTROMETRIC SPECIES DETECTION CAPABILITIES WILL BE DESIGNED. THE PROPOSED DESIGN, UTILIZING AEROCHEM'S EXPERIENCE IN CONSTRUCTING AND USING SIMILAR APPARATUS, WILL EXCEED THE UPPER TEMPERATURE AND PRESSURE SPECIFICATIONS GIVEN IN THE SOLICITATION IN ORDER TO GIVE THE INSTRUMENT GREATER UTILITY. ALTERNATE ...

ALTHOUGH THERE ARE NO INTRINSIC CONFLICTS FOR THE SAME MATERIAL SYSTEMS TO ACHIEVE BOTH THE RADAR ABSORPTION AND THERMAL SUPPRESSION CHARACTERISTICS THERE EXISTS NO COMMERCIAL PRODUCT THAT HAS THE DESIRED DUAL PROPERTIES. A THEORETICAL CALCULATION ON THE FEASIBILITY OF SEVERAL PROPOSED MATERIAL SYSTEMS WILL BE PERFORMED. THE CALCULATIONS ARE BASED ON A MEAN FIELD THEORY FOR DIELECTRIC PROPERTIES. ...

MAKING ACCURATE AUTOMATED ON-WAFER MEASUREMENTS OF MILLIMETER-WAVE SEMICONDUCTOR DEVICES AND CIRCUIT ELEMENTS IS A FUNDAMENTAL REQUIREMENT FOR THE ADVANCEMENT OF A MILLIMETER-WAVE TECHNOLOGY. MILLIMETER-WAVE WAFER PROBE DEVELOPMENT IS REQUIRED. PRESENTLY ON-WAFER PROBING IS AVAILABLE ONLY TO 26.5 GHZ. HOWEVER, SIGNIFICANT INNOVATIONS ARE REQUIRED TO EXTEND THIS CAPABILITY OF HIGHER FREQUENCIES. TH ...
