Small unmanned aerial systems (UAS) are a critical element in current military operations, and their use will increase substantially in the future. The propulsion system is a key design constraint in any UAS, and current small gas turbines for these vehicles are limited by the conventional oil-lubricated rolling element bearings used to suspend their high-speed rotating assemblies. Gas-lubricated ...

Effective Army-scale mobility predictions in austere environments require knowledge of soil strength conditions at high spatial resolution (100 m or less). Knowledge of the battlespace is greatly hindered because available weather-scale near-surface soil moisture data, a primary indicator of soil strength, is limited by its coarse spatial resolution (125 km). Moreover, there are no adequate method ...

Interfaces on existing military chemical/biological protection garments are not designed to fully eliminate macroscopic and microscopic air gaps at folds, fabric surfaces, or hook-and-loop closures, and thus do not provide a hermetic barrier against exposure. Creare proposes to develop a hermetic garment closure system that seals macroscopic and microscopic gaps at interfaces and closures and pro ...

Power system upgrades for next generation ground combat vehicles require technology advances such as higher operating temperature, greater power density, and increased functionality. Silicon Carbide (SiC) based power electronic devices offer advantages over silicon devices, especially for high voltage buses, and Creare is currently developing a SiC based 12 channel, +/ 300 VDC Solid State Electric ...

Chemical, biological, or toxin attacks in military and civilian settings are a serious and growing concern. Standard first aid for exposure to some chemical warfare agents and toxins includes the immediate administration of relevant antidotes using an autoinjector. When an attack occurs, pre-filled autoinjectors must be immediately available and thus highly portable, and they must be suitable fo ...

The overall objective of the proposed effort is to develop an improved ultrasonic consolidation (UC) process for metal matrix composites (MMCs). The Phase I effort demonstrated the feasibility of using a fiber-matrix unit cell finite element analysis to study the thermal and acoustic softening that occurs during UC. The analyses completed in Phase I highlighted the need for uniform prepreg mater ...

During covert operations, the U.S. Army may be required to breach a concrete structure using a controlled explosion. When choosing the most effective charge size and placement, it is vital to perform a rapid field assessment of the material and structural properties of the target structure. However, high strength concrete materials (such as Ultra-High Performance Concrete), including steel fiber r ...

During Phase I, the Blackhawk hanger bearing and oil cooler fan bearing applications were studied in detail, including analysis of vibration and temperature data from used oil cooler bench tests (conducted by Sikorsky) and used hanger bearing bench tests (conducted by Sentient). This data, along with an analysis of operational and environmental conditions, has allowed us to identify the probable r ...

We propose to develop multiresolution representations and algorithms for synthetic terrain environments. They will be used for representing large terrain models as well dynamic and atmospheric simulations. Our ultimate goal is to increase the validity of the simulation by incorporating the multiple models at varying resolutions. We will use the OneSAF simulation Product Line Architecture Framework ...

DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...
