The primary technology developed under this program will be an advanced flowfield diagnostic system to provide comprehensive reactive scalar measurements in high speed, turbulent reacting flows. Such a diagnostic technique is needed to support computational modeling advancements that are critical to support Army force protection requirements against tactical and theater ballistic missile threats.T ...

Army defense technologies for high speed, lethal threat intercept increasingly rely on high maneuverability of the kill vehicle through both aerodynamic and thrust augmentation while the threats themselves have relied on equally increasing maneuvering defenses to avoid intercept. Because it is in the interest of defense systems to target the threat as early as possible, intercept locations in high ...

The effort proposed by General Sciences, Inc. (GSI) is based on using available nanosize additives which upon reaction within the detonation front will enhance blast and impulse (in the case of the explosive) as well as increase thrust, impetus and projectile-velocity in the case of propellants. Inclusion of other additives to conventional explosives and propellants upon reaction produce finely su ...

Through this effort, we propose to develop SampleFlex, an elastomer-based field-capable sampling technology for collecting and preserving blood samples. Our approach improves upon paper-based blood collection methods which utilize dried filter paper cards for Dried Blood Spots (DBS) by encapsulating the sample within a flexible elastomer package to protect the sample during transport and storage.R ...

New regulations and advisory levels for perfluoroalkyl substances have resulted in increased drinking water treatment costs or abandonment of drinking water sources. Treatment technologies are needed that can achieve low parts-per-trillion levels. Presently, there are insufficient treatment technologies that can destructively remove perfluorooctanoic acid (PFOA) and/or perfluorooctane sulfonic aci ...

To reach the end user, oil and gas production at the wellhead must be transmitted through the country and distributed to a wide range of customers. This logistical system requires natural gas gathering lines, processing facilities, product storage tanks and lots of other equipment. What results is air pollution caused by industry losses during these operations and the use of continuous or intermit ...

Ultran will develop and prototype the transducer technology and initial system prototypes for a wearable system for imaging and modulation of peripheral nerves. Transducers developed for energy delivery will use Ultran's gas matrix piezoelectric (GMP) technology while those for imaging may use either GMP and piezoelectric micromachined ultrasonic transducers prototyped by a supplier. Miniaturized ...

Wearable, high image quality, low power, conformable ultrasound capable of delivering acoustic energy for nerve modulation

Missile base flow prediction is an area that has eluded a satisfactory solution since the 1950's owing to the complex aero-thermo-chemical physics of this region involving flow separation, two-phase gas/particle non-equilibrium, chemical kinetics, and flow turbulence in complex geometries. Additional complexities are introduced when considering alterations to the base flow structure and plume turb ...

The primary objective of this effort is to develop an advanced turbulent combustion model to accurately capture local flame extinction effects that result in afterburning missile plume flame lifting and rapid afterburning shutdown. Such a modeling formulation is critical to enable the Army to effectively fulfill force protection requirements against tactical and theater ballistic missile threats. ...
