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 ...

The goal this work is to use AI to interpret the THz and sub-THz responses at the pins to the defects and deviations from design of the integrated circuits under test. The key application is work is identifying hardware security treats using artificial intelligence (AI) for cyber security applications. Our approach will provide a rapid, inexpensive, and non-destructive technology address this prob ...

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 ...

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 ...

Physically uncloneable functions (PUFs) have the potential to revolutionize cybersecurity by forming the basis for next-generation secure networks and trusted computing environments. During Phase I, Potomac Research and OSU evaluated of three physically uncloneable function (PUF) designs that can be implemented on COTS FPGAs. One design based on hybrid Boolean networks (HBN-PUFs) emerged as the cl ...

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 ...

The objective of this Navy Phase II STTR program is to design, develop and manufacture energy scavenging modules for “small unit power” architecture. The energy scavenging modules (ESMs) developed in this program will be able to capture the magnetic fields surrounding electrical power lines and electrical equipment and convert their energy into electricity. The ESMs will be designed to have th ...

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 ...

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 ...

TrueNano, Inc. will in collaboration with the University of Colorado and industry partners, produce a novel single wafer, high throughput, cold wall Hot Filament CVD (HF-CVD) reactor prototype for the growth of high-quality silicon carbide (SiC) epitaxial layers, suitable for the next generation of power electronic devices and systems. This includes the design and simulation of the reactor chamber ...
