The purpose of this STTR is to develop comprehensive detailed kinetics for oxidation of C-SiC-SiO2-rubber in extreme oxidizing environment. This material is used as a coating on the outer surface of Navy weapon systems. In order to predict the fate of this material under extreme conditions and mitigate the degradation of the coating, a comprehensive oxidation mechanism is required. In Phase I, CFD ...

The overall objective of this effort is to identify, and validate a suitable methodology and the associated multi-scale computational technique for predictive assessment of corrosion fatigue damage in Naval aircraft. Annual costs for corrosion inspection and repair of military aircraft are estimated to exceed $1B. Predictive modeling of corrosion fatigue damage is challenging since it has to captu ...

Iris Technology, in collaboration with Georgia Tech and Raytheon, proposes to perform advanced 3D CFD modeling to guide the architecture selection for a tactical 4K Cryocooler. Iris will lead the System Design and Program Management efforts. Georgia Tech is the lead organization on the Analysis. Raytheon is providing the underlying mechanical cryocooler technology. The preliminary technical base ...

SA Photonics, in conjunction with our teammates at the University of Arizona, have developed LARS, the low-cost augmented reality system. This system is a see-through HMD used for training and simulation. LARS was designed using an innovative freeform prism combiner which is small, lightweight and has very little obscuration of the outside world. We have partnered with Rockwell Collins Optronics ( ...

Acellent Technologies Inc. and Prof. F. G. Yuan at North Carolina State University (NCSU) are proposing to develop a Hybrid Distributed Sensor Network Integrated with Self-learning Symbiotic Diagnostic Algorithms and Models to determine materials state awareness and its evolution, including identification of precursors, detection of microdamages and flaws near high stress area or in a distributed ...

Complex software systems are typically developed by disparate engineering teams working concurrently. At the same time, software requirements are frequently dynamic, evolving even during active development cycles. Discrepancies between how software is defined and how it is implemented at the modular level can cascade into critical system errors when modules are integrated. More troubling is that i ...

Yotta Navigation and The Ohio State University propose to develop a complete diver text messaging and locator system. The system will securely transmit preformatted and free-text messages, and will be able to accurately determine range and bearing, at distances of up to 1000 meters. This system consists of two major components. An ultrasonic cylindrical array, mounted on a swimmer delivery vehicl ...

Turbine efficiency improves with increased operating temperature. Consequently, the rim zone of disks operates at high temperatures where creep is the main concern. The bore and web zones operate at lower temperatures, where strength is the driving design criterion. Procedures to produce disks that can meet both demands include dual heat-treatment and hybrid disks. A thin transition zone forms in ...

A high-voltage, high-capacity, inexpensive cathode material for lithium-ion batteries (LIBs) is proposed. The cathode material employs carbon nanotubes and additional nanostructures to support efficient transport of Li ions. The resulting LIBs will support high transient and pulsed loads while offering enhanced safety and lifecycle performance. Proof-of-concept LIB cells were demonstrated in Phase ...

For Unmanned Aircraft Systems (UAS) to operate seamlessly in both the U.S. National Airspace System (NAS) and abroad, it will be crucial that they possess a sense-and-avoid (SAA) capability that can ensure safe operations among maneuvering, non-cooperative aircraft. Numerica Corporation, in partnership with Johns Hopkins University, proposes to develop a set of algorithms to model the uncertaintie ...
