Silicon carbide(SiC)semiconductors offer revolutionary improvements in power electronics due to much lower conduction and switching losses, higher switching frequencies, higher voltage capability, higher operating temperatures and other superior properties relative to standard silicon devices. In Phase I, SiC MOSFETs were tested and characterized, confirming lower losses. It is projected that lo ...

Extremity fractures are a significant concern in both the civilian and military populations. In the military experience, extremity fractures can sometimes comprise the majority of peacetime orthopaedic injuries. During armed conflict, bone trauma from penetrating missiles is similarly significant, as the experience in the Persian Gulf and Croatia has shown. Anti-personnel mines and improvised e ...

The objective of this proposal is to improve the computational tools identified in Phase 1 that will be useful in assessing rocket and missile propulsion systems for compliance with insensitive munitions (IM) requirements. Comprehensive testing to ascertain IM compliance for such systems is time-consuming and expensive. High-fidelity computational tools exist that can be used to address the asse ...

MicroPhase Coatings, Inc. (MPCI) proposes to develop polymer liners for lightweight gel propulsion storage tanks under SBIR Phase II Topic A02-144. Polymer liners provide lightweight, long term, safe storage of Inhibited Red Fuming Nitric Acid (IRFNA) geland Mono Methyl Hydrazine (MMH) gel used in missile and space propulsion systems. The Phase II effort produces prototype gel propulsion tanks tha ...

This Phase II effort develops fiber grating sensors to measure transverse strain/pressure, shear strain, and temperature, in the vicinity of the bond line. Methods are developed to support ingress/egress from tactical rocket motors of fiber grating sensorarrays. Related testing of fiber grating strain sensors are performed using known and controlled boundary conditions and thermal loading in rep ...

We propose to continue the development and characterization of a polymeric nanoencapsulation technology that can increase the lifetime of a protein therapeutic agent within a biological system. The materials have been demonstrated to exhibit no cytotoxicity and to efficiently deliver antibody against Protective Antigen of bacillus anthracis.

The Army desires to develop advanced computer models of Aircrew Integrated Helmet Systems (AIHS), such as the HGU-56/P, for use on existing and future headform databases. These models must analyze the interrelationship between AIHS and headforms.Comfort, Protection, Performance and Compatibility (CPPC) evaluation of AIHS and ground forces helmets will be the primary objective. Visual Sciences, I ...

Shrouded-fans play a key role in the U.S. Army's transportation systems. A preliminary design tool capable of simulating the flow field in different flight conditions for predicting the shroud and fan performance can significantly reduce design costs. Thisproposal offers a computational tool that will lay the foundation for true transient wake calculations of a shrouded-fan in axial and non-axial ...

A mobile platform is proposed for aquatic in-situ toxicant detection featuring living biosensors. This platform or BioSensor Suite comprises a sentinel species biosensor, water quality monitoring sensors and a water sampler. The BioSensor Suite will bedeployable as an integrated sensor package on the Ranger TA (Toxic Alarm), a 10 lb micro-UUV. The proposed effort will include system design, fab ...

Software development organizations are faced with developing and verifying required system software capability, functionality, performance, reliability, and safety, while at the same time meeting tight budget and schedule constraints. Due to software complexity, many programs experience mission critical failures and incur schedule delays and cost overruns. The Army and other organizations, there ...
