The primary objective of this effort is to develop a tractable computational tool to assess the probability of ignition within aircraft combustors and augmentors during routine igniter and/or system design analysis. This computational tool will provide for the off-line assessment of ignition probability given flowfield simulation data, characteristic igniter geometric and physical parameters, and ...

The objective in this project is to implement and validate a probabilistic qualification framework that will enable additive manufacturing (AM) materials and part qualification through the use of a data-driven predictive model within a statistical framework. Senvol seeks to develop and validate a data-driven ICME probabilistic framework for assisting qualification of AM materials and parts. Phase ...

Superconductor digital circuits, operating at very high clock speed, can directly process wideband digitized radio frequency (RF) signals. By integrating such digital processing circuitry together with superconductor analog-to-digital converters (ADCs), we propose to develop the next generation digital-RF receivers. Leveraging the recent development of multiple superconductor ADCs on the same chip ...

High-speed flight vehicles commonly use carbon / carbon (C/C) and carbon / silicon carbide (C/SiC) for structural components. These materials are chosen because of their superior structural properties at elevated temperatures. Most often, their properties are characterized using flat and thin material test plates. While this approach is convenient, it is not guaranteed to yield material properties ...

Silicon-on-sapphire (SOS) integrated circuits have achieved popularity due to their high speed performance and low power consumption in radio frequency applications. An important aspect of the SOS fabrication process that must be verified to maximize yield is the thickness of the thin films deposited on the sapphire substrate. However, due to the transparent nature of sapphire, current optical met ...

latereThis proposal describes the development of a process to synthesize low defect Ge1-xSnx and SiyGe1-x-ySnx layers on silicon and silicon-on-insulator (SOI) substrates through low thermal budget laser and rapid thermal annealing/crystallization for high performance mid-wave infrared (MWIR) photo detectors and integrated Si-based optoelectronic devices. In phase I, we demonstrated synthesis of G ...

This phase 2 proposal builds upon Phase 1 successes, with plans for the construction of an electrochemical variable emissivity device (EC VED). The viability of this EC VED will be determined by the development of a new family of ionic liquid (IL) electrolytes featuring polyhedral boron cages as the anionic component. In these new electrolytes, the negligible vapor pressures and high ionic conduct ...

Developing knowledge-driven nanoelectronics for military applications requires understanding the fundamental physics that governs the behavior of the underlying materials. Strongly correlated materials have very desirable properties such as interfacial superconductivity, ferroelectricity, ferromagnetism, and huge magnetoresistance, which make them an ideal set of candidates to integrate with semic ...

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 ...

As threats emerge in geographically diverse locations, precision responses are often required immediately.However, the time-to-target for many munitions can be simply too long for short lived opportunities.To enable timely responses to long range threats, hypersonic munitions with velocities greater than Mach 5 are necessary.However, with hypersonic velocities comes a significant increase in the a ...
