High Cycle Fatigue (HCF) characterization and maintenance accounts for a significant portion of the overall life cycle cost of most military propulsion systems.  A key variable that drives HCF margin is dynamic response which is directly related to the geometry of each part.  This is especially true of integrally bladed rotors (IBRs, or blisks).  It has been well established that HCF is a proba ...

Predicting the emission signature and radar cross-section of rocket exhaust plumes is of vital interest to the Missile Defense Agency and U.S. Army to protect the U.S. homeland and our forces abroad.  The current STTR Phase II project has shown that a single-conditioned Premixed Conditional Moment Closure (PCMC) can employ detailed chemical kinetic mechanisms while efficiently modeling combustion ...

Solid oxide fuel cells have long suffered from degradation due to impurities in the fuel and complexities associated with dissimilar materials and high operating temperatures. This degradation lowers the usable cell power output and requires ancillary equipment for fuel sulfur removal and reformation. A unique microstructure for a tubular anode-supported SOFC is being developed using a novel freez ...

This DOD Phase II STTR program would develop self-calibrating, conformal nanomembrane based pressure sensors for embedded sensing applications, using silicon on insulator techniques in combination with our pioneering nanocomposite materials. Such low-modulus, conformal nanomembrane sensor skins with integrated self-calibration, interconnect elements and electronic devices can be applied to new or ...

Naturally occurring periodic nanostructures have long been of interest due to their striking optical effects and potential biological roles. They have been recognized not only as interesting curiosities but potential design inspirations that can lead to improvements in biochemical sensors, laser surgery, photovoltaics, and other mission-critical applications. This work will focus on one such appli ...

Advanced Air Force turbine engines with integrated engine exhaust systems require diagnostic flow measurements. Integration of these systems into altitude test cells creates problems with T&E requirements such as impingement problems, exhaust cooling spray blowback, acoustic emission issues and limited space for measurement systems. Propulsion system analysts need better understanding of low aspec ...

In this Special topic AFWERX program, NanoSonic shall explore our commercial product, HybridSil™ ICEPHOBIC nanocomposite combined with WashU’s Distillation Membranes as a Defense-Related Dual-Purpose technology for near-term Air Force Civil Engineering Center (AFCEC) military functional hybrids (AFOSR FOCUS AREA RTB2) and commercial water purification markets.  A current dual use need for Hyb ...

Hazard assessment tools that model the transport and dispersion of Chemical, Biological, Radiological, Nuclear and Explosive (CBRNE) materials through urban areas are only as good as the 3D models that inform the physics model. Maintaining accurate, up-to-date 3D models of urban areas is challenging. Even in the commercial world, urban construction and demolition may result in the models created a ...

This project delivers a compact system to assess and reduce local uncertainties that impact routing and sensor operation decisions while tracking the evolution of the maritime environment around unmanned platforms at sea (UUV/USV). The system runs both at control centers and on-board the UUV/USV’s, subject to different network bandwidth and computing environments Size, Weight and Power (SWaP) co ...
