The objective of the work described in this proposal is to aid in the advancement of Mo-Si-B alloys for use in high temperature applications such as hot gas stream components in turbine engines. Such alloys are being characterized for their monotonic tensile properties in tension and compression as well for their creep resistance. Likewise, multiphase Mo-Si-B alloys have been studied in terms of m ...

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 ...

PowerTHRU Corporation proposes to meet or exceed the requirements of this STTR by utilizing its extensive experience in carbon fiber based high speed flywheel systems, to design and build a 100K RPM flywheel system. Unlike steel flywheel technologies that are limited by the speed in which they can safely rotate, PowerTHRU has already demonstrated that 50,000 RPM carbon fiber flywheels can be desig ...

Improving situational awareness and accuracy of decisions in complex missions relying on streaming open-source data requires scalable information extraction and fusion in collaboration between Man and Machine reasoning. SoarTech, with its proven track-record of basic and applied research and transition into actual deployment, will bring forward advanced imagery and text processing technology integ ...

Phase I of the STTR program will be a collaborative research effort between high fidelity computational simulations and experimental testing. The primary aim of this initiative will be to measure laser beam distortion, using aero-optic metrics, due to flowfield turbulence. The results from the computational simulations and experimental test will be compared to ensure agreement between the two. Ini ...

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 ...

Corrosive environments together with cyclic loading can lead to the formation of localized corrosion pits and corrosion fatigue cracks, which can significantly deteriorate the structural integrity of aircraft components. The exact nature of corrosion fatigue damage is dependent on the competing multi-scale processes resulting from complex interactions between the structural material, its environme ...

It is critical to the safe use of ceramic matrix composite components that information on the fracture toughness of these materials be available, in order to allow an assessment of the likelihood for crack growth. Although Military Standards and American Society for Testing and Materials both serve as resources for room and elevated temperature test methods, there are no standards to obtain the in ...

The use of laser technologies and high-power electronics is rapidly being incorporated into tactical platforms for imaging, target designation, and range finding. Electronic equipment including lasers demand power from a tactical aircraft and produce large amounts of thermal energy as a waste product. Current thermal management technologies will not be sufficient for future aircraft as thermal man ...

As underwater threats continue to evolve, active sonar systems and operators must evolve with them, requiring improvements to sources, receivers, signal processing algorithms, and search mission planning applications in order to maintain and improve detection rates. Any improvements in the latter requires a detailed and accurate understanding of the acoustic underwater environment, and the underly ...
