Propagation Research Associates, Inc., (PRA) proposes to utilize its unique capabilities in atmospheric effects characterization and GPS signal processing to develop algorithms that nowcast ionospheric scintillation at GPS frequencies. To this end, PRA proposes to partner with the Jet Propulsion Laboratory to use real-time GPS data to create a map of ionospheric scintillation parameters over the ...

With the notable exception of glucose, most metabolic biomarkers cannot be accurately, and practically measured over long periods, in vivo and in real-time. A primary reason is stable, selective enzymes suitable for biosensors are not available. Biosensors could revolutionize acute and long-term monitoring in the development, clinical, first responder and battlefield arenas. Pinnacle has develo ...

Aircraft, missiles, and vehicle structures are susceptible to corrosion. Engines, transmissions, blades, rocket motors, canisters, and other system components include materials that degrade over time and are not often checked. Recently, the application of condition-based maintenance (CBM) techniques has reduced lifecycle maintenance costs through the identification of maintenance needs after analy ...

Under this effort, Sentient will develop mixed-EHL models to predict the performance of fluid film bearings for submarine applications. The models will consider critical design and operational parameters such as component geometry and surface finish, start up and shut down speeds/loads, and lubrication properties to predict torque, film thickness, and associated wear/efficiency. The result will be ...

This STTR is aimed at developing methods and tools to characterize the impact of free-play on control surface flutter and overall stability and performance of the system. A successful completion of this two-phased STTR effort will lead to a modeling, analysis, design, and simulation tool that will provide a state-of-the-art capability for stability and performance analysis for any generic control ...

Global Technology Connection, Inc., in collaboration with their academic partners and industrial partners propose to develop a prototype integrated physics-based model and accelerated testing process that will reduce the qualification time and testing required for Li-ion cells used in LEO/MEO satellite applications. The integrated physics-based model will focus on three key Li-ion cell degradatio ...

The proposed research incorporates several inventions to produce structural components that are assembled into a highly enhanced Toxic Material Forensic Container (TMFC) for transport and storage of contaminated articles. Bio-hazardous materials are frequently encountered in investigations, and the current evidence containers are designed to handle the issues associated with those materials. Howe ...

During initial design studies, parametric variation of vehicle geometry is routine. In addition, rotorcraft engineers traditionally use the wind tunnel to evaluate and finalize designs. Correlation between wind tunnel results and flight tests, when not good, have been often attributed in part to uncertainty in blockage corrections. Estimation of rotor blockage is significantly more complex than bl ...

Advanced reconfigurable/reprogrammable communication systems will require use of commercial sub 100 nm electronics. Legacy radiation tolerant circuits fail to provide Single Event Upset (SEU) immunity at speeds greater than 500 MHz. New base level logic circuits have been demonstrated in Phase I that provide SEU immunity for sub 100 nm high speed circuits. A completely new circuit and system ap ...

In this highly interconnected world, transportation systems must feature increased flexibility and shorter door-to-door trip times to be successful. Shorter door-to-door trip times require an increased usage of rotary wing and runway independent V/STOL technology. One of the limiting factors to the increased adoption of this technology for providing feeder service to major hubs is the limited un ...
