ABSTRACT: In Phase I, CFDRC in partnership with ESI, have developed and validated a physics-based CFD tool to quantify fuel spurt caused by impact and penetration of fuel tanks. CFD tool development, qualification and validation study showed good correlations with experiments in terms of fundamental physics including: a) droplet formation, breakup, size, timing and distribution; b) cavitation zone ...

ABSTRACT: The rapid continued development of unmanned air systems (UAS) is enabling new mission types, in-creased mission effects, and increased airman safety. However, these advances also present numerous challenges to airman-machine interaction, tactics development, and defense. The rapid development pace has produced a situation where new technologies are outpacing the knowledge of how best to ...

ABSTRACT:nou Systems proposes an innovative analysis and test methodology for testing space-based high-resolution wide field-of-view (WFOV) focal plane arrays (FPAs). Current space sensor test facilities are incapable of fully testing state-of-the-art high-resolution WFOV sensors without infrastructure modifications. The test methodology described in this proposal focuses on testing only a subset ...

ABSTRACT:As weapon velocities increase significantly in the coming years, driven by reduced response times and by the strength of materials in target structures, the already-significant shock loads on explosive payloads and fuze components will be greatly exacerbated. Given that the integrity of the payload and fuze components is critical to proper weapon functioning, it is imperative that solutio ...

ABSTRACT:The overall goal of the project is to develop reliable reduced order modeling technologies to automatically generate parameter-varying aerothermoservoelastic (ATSE) reduced-order models (ROMs) for fast Fluid-Thermal-Structural Interactions (FTSI) assessment and control system design. The Phase I effort will focus on developing several key components, including parameter-varying formulatio ...

ABSTRACT:The proposed research will examine innovative approaches for real time simulation of the coupled fluid-thermal-structural response of hypersonic muntions operating on terminal trajectories for the purpose of high-fidelity closed-loop guidance and control. This will be accomplished by combining state-of-the-art model reduction approaches for CFD aerothermodynamics and FEM thermo-structural ...

ABSTRACT:The feasibility of developing a photonics-based real-time high-power-microwave (HPM) near-field mapping system is to be investigated. The system is intended to contain multiple non-intrusive near-field sensors so that it can simultaneously detect undistorted versions of broadband HPM electric- and magnetic-field transients over a desired field-mapping area. The system will be able to take ...

Trauma is the leading cause of death in civilian and military environments and acute hemorrhage contributes to a large portion of these fatalities. Recent experience from Iraq and Afghanistan has demonstrated the crucial role of blood products in the care of critically injured soldiers. Unlike plasma and red blood cells, which can be cold stored for longer time periods, platelets can be safely sto ...

ABSTRACT:IR Telemetrics will leverage its existing data acquisition technology to design, build, and demonstrate a Compact, High Channel Count, High Frequency, Rotating Data Acquisition and Transmission System. The modular, scale-able system will digitize with over 18-bit resolution and a minimum 300 kSPS sample rate and be able to spin at over 25,000 rpm. Data transmission will be accomplished wi ...

ABSTRACT: Designing an efficient and effective film cooling system to protect critical components of modern rocket engines requires a significant number of challenges to be addressed. Complicating the already difficult hydrodynamic challenges, thermal cracking of hydrocarbon fuels is always accompanied by coke formation. The coke deposits on the combustor and nozzle walls reduces heat fluxes and c ...
