The accurate representation of the rotor wake, especially the tip vortex structure, in a computationally efficient and algorithmically straight forward way is crucial for prediction of rotor aerodynamic performance, noise emission, and rotor structural dynamics. A promising approach for design and optimization is the vorticity confinement (VC) method that minimizes the numerical diffusion of vorti ...

TechFlow Scientific proposes to develop a dynamic high-power radio-frequency (HPRF) engagement modeling and simulation (M & S) tool for predicting weapon effectiveness in Navy surface engagements, leveraging past related work to advance the development schedule. Our team brings considerable experience in HPRF M & S and analysis, software development, and integration of individual tools to create c ...

Tyco Electronics Connectivity Defense and Aerospace (TE) is a leading supplier of mil-spec fiber optic (FO) connectors used in ship"s wiring plants, In a Navy SBIR, our company, Management Sciences, Inc. (MSI) worked with TE and developed a portable automated test equipment (ATE) for fast and efficient troubleshooting of harnesses. The portable ATE operates at the rate of about 4 seconds per condu ...

The proposed project will undertake the research, design, and development of key concepts and technologies for a high-speed electronically tunable channel filter, based on monolithically integrated ultra-high-resolution super-compact grating (UHR-SCG) technology that has been developed in OptoNet. The grating will be realized on Silicon-Photonic Electronic-Photonic Integrated (EPIC) Platform that ...

Pipelined radiation hardened analog-to-digital converters (ADC) typically provide 12-14 bit resolution conversion at >20 MSPS and have inherent multi-clock cycle latency. These converters use multiple sub-ranging stages and error correction circuitry and the high parts count results in large silicon footprints. ATA proposes designing an Advanced Radiation Hardened ADC (ARH-ADC) by implementing the ...

KaZaK Technologies and our program subcontractors and technical associates are proposing several concepts to reduce Medium Tactical Vehicle Replacement (MTVR) wheel hub weight to increase cargo capacity and improve vehicle handling. An increase in cargo capacity provides the MTVR to be outfitted with the MAS up armor protection minimizing impacts to vehicle performance. One obvious approach to red ...

A reduced hazard antenna design will be developed for deployment on handheld and manpack radios. High voltage protection will be built into the antenna to prevent accidental electrical contact with high voltage power lines up to 25kVDC RMS. Prototypes of the high voltage protection devices will be developed and tested. The antenna design will be modeled before constructing a bench prototype, which ...

In this Phase I SBIR program, QuesTek Innovations, a leader in the field of integrated computational materials engineering (ICME), proposes to design and develop novel aluminum alloys specifically optimized for the unique processing conditions and challenges of Additive Manufacturing processing. QuesTek is uniquely suited to rapidly designing new aluminum alloys specifically optimized for AM proce ...

MicroLink Devices has developed, and is currently producing, thin epitaxial lift-off inverted metamorphic solar cells for flexible solar sheets using a four-inch GaAs wafer platform. These cells have been demonstrated in a variety of applications including panels attached to Marines"backpacks and the wings of Raven and Puma unmanned aerial vehicles (UAVs). Although good system performance has su ...

The goal is to develop external mechanical filters to eliminate signals above 2 kHz from accelerometers. Domincas patented layered-media approach will be used to develop filters for high-shock accelerometers used in explosive and impact events. Layered-media theory has been applied successfully in optical thin films, acoustics, and signal transmissions. Filters with and without viscoelastic materi ...
