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 ...

Optonicus, in collaboration with the University of Dayton has demonstrated the feasibility of a new Scalable Adaptive Fiber-Array Elements (SAFARE) phased fiber-array beam director architecture in Phase I to address the DoD need for HEL directed energy systems. The SAFARE system integrates a new high fill factor fiber-array architecture with novel imaging, sensing, and control capabilities that en ...

ABSTRACT: Temperature and magnetic field dependent terahertz spectroscopies have proven useful for characterizing novel electronic and magnetic materials. To this end, we are developing a turn-key, continuous-wave (CW) terahertz transmission platform operating from 5 K to 300 K with fields up to 9 T. Fiber-coupled photoconductive switches operate from 200 GHz to 1.2 THz in the cryogenic and high-f ...

"The U.S. military tactical vehicles currently use a ceramic tile based composite armor system in situations where a lightweight armor system is desired to provide protection against blast fragments and ballistic projectiles while maintaining adequate mobility and survivability. However, the current ceramic tile based composite armor system, which are generally manufactured using Vacuum Assisted R ...

We propose an intelligent assessment concept that will discover and reason about KSAs in multiple instruc-tional domains and settings. SoarTech will team with world-class researchers from the University of Califor-nia, Davis and the University of Memphis to research and develop TARGET: Transfer via Active Requests to Generalize Effective Training. TARGET will enhance SoarTechs assessment system DA ...

The Phase I research effort proposed here is to design and demonstrate first-generation laser-absorption-based sensors for time-resolved measurements of combustion-product mass fractions and gas temperature within the detonation channels and at the nozzle exit plane of rotating-detonation-engine (RDE) systems. An important element of this work will be the development of criteria to optimize the se ...

Ultra-high-performance concrete (UHPC) offers superior properties for structural applications. Existing UHPC design and production methods employ special materials and mixers. This project is developing mix design and fabrication methods for reliable production of UHPC with local materials and facilities. The Phase I project devised material selection criteria, proportioning methods and mixing pro ...

The research objective of this proposal is to demonstrate feasibility to collect and interpret in situ 3-D surface data for the laser sintered top surface for each layer in a powder bed process. The 3-D data collection will be performed with no interference with the operational efficiency and build time for the powder bed process. The 3-D data will be utilized to compute the distributions of surfa ...

Although advancements in CFD technology and high performance computing have proven to be effective in assessing the hydrodynamic performance of naval vessels, the effort required to develop analysis models remains challenging and time-consuming. Decomposing and manipulating design geometry for mesh construction, while capturing flow characteristics and interactions among moving components, are man ...

ABSTRACT: The goal of this proposal is to demonstrate the feasibility of a novel environmentally-compliant process to produce an advanced alloy coating(s) that imparts excellent corrosion and wear resistance to structural metals on military aircraft and weapon systems. The resulting composite coating and the coating process do not consist of any hazardous materials such as heavy metals chromium (C ...
