SBC: NUTRONICS, INC. Topic: AF18AT006
Through the execution of our Phase 1 effort, Nutronics, Inc. and Montana State University developed an improved means to optimize the Pellizzarri cost functional for coherent imaging using digital holography. Our algorithm developed during the Phase 1 effort accelerates convergence times by a factor of 20-40 for the majority of scenarios evaluated. Our proposed Phase 2 effort has a two-fold focus: ...STTR Phase II 2019 Department of DefenseAir Force
SBC: ARCTOS Technology Solutions, LLC Topic: DLA18A001
This Phase II project aims to assemble the key set of sensor modalities that are needed to reliably view the key process anomalies and properties of laser powder bed fusion. The research team will down-select from the Phase I sensors investigated and integrate the sensors into a sensor fusion software package that facilitates data collection and synchronization, and eventually feedback control of ...STTR Phase II 2019 Department of DefenseDefense Logistics Agency
Fidelity Enhancement of Nuclear Power Plant Simulators Utilizing High Fidelity Simulation PredictionsSBC: WESTERN SERVICES CORPORATION Topic: 30c
Accurate simulation of nuclear power plant behavior is necessary for both engineering and training applications. An engineering grade simulator, used for design, safety analysis and operations, is characterized by high fidelity, computational power, lack of real-time capability, and user non-interactive environment. By contrast, a training grade simulator, used for operator training and education, ...STTR Phase II 2019 Department of Energy
SBC: Electro Magnetic Applications, Inc. Topic: T5
We propose the development of a user-friendly software tool for estimating the electric field distributions within spacecraft enclosures based on the Power Balance (PwB) method and enhanced by a database of experimentally determined Absorption Cross-Sections (ACS) of common equipment, components and cables.The software will be built around an already developed PwB solver that determines the statis ...STTR Phase I 2019 National Aeronautics and Space Administration
SBC: PLASMA CONTROLS, LLC Topic: T2
Plasma Controls, LLC (SBC) and Colorado State University (RI) will mature an energy and species plasma diagnostic for use with plasma thrusters. The combined Energy and Velocity Analyzer for Distributions of Electric Rockets, or the lsquo;E-VADERrsquo;, is needed especially for characterizing the plasma plume of Hall thrusters, where researchers desire to know ion energies and charged species frac ...STTR Phase I 2019 National Aeronautics and Space Administration
SBC: CORNERSTONE RESEARCH GROUP INC Topic: T15
Electrified Aircraft Propulsion (EAP) research is part of NASA effort to improve aircraft fuel efficiency, emissions, and noise levels. New secondary battery chemistries are required to meet the 500 ndash; 700 Wh/kg cell level specific energy needs of UAM, all-electric helicopters and regional passenger aircraft. The cycle life, currently at asymp; 1500 ndash; 3000 cycles, also needs substantial i ...STTR Phase I 2019 National Aeronautics and Space Administration
SBC: VETH RESEARCH ASSOCIATES, LLC Topic: T4
Technology currently used for terrestrial navigation is extremely limited in the challenging environments on icy moons and ocean worlds such as Europa. Autonomous platforms used to collect data from beneath these ice and ocean surfaces cannot depend on access to satellite or any other electromagnetic communication. Autonomous systems in these environments are required to perform highly-complex tas ...STTR Phase I 2019 National Aeronautics and Space Administration
SBC: OPTERUS RESEARCH AND DEVELOPMENT, INC Topic: T12
Opterus proposes to develop braided thin ply composite tapes. The tapes will be braided from ultra-thin spread-tow unidirectional carbon and glass ribbons and will enable a new source and form factor for thin-ply textiles. The resulting tapes will be especially useful for thin high strain composite space deployable structures where they will allow bias plies in long parts without requiring seams. ...STTR Phase I 2019 National Aeronautics and Space Administration

The aim of the proposed program is to design metasurface structures to manipulate electromagnetic waves of extremelynbsp;different frequencies, from visible light to THz.STTR Phase I 2019 National Aeronautics and Space Administration
Concurrent High-Fidelity Measurements and Simulations for Advancing the Design of Rotating Detonation EnginesSBC: SPECTRAL ENERGIES LLC Topic: T2
Rotating Detonation Engine (RDE) design is challenging due to the lack of in-depth understanding of many key mixing and combustion processes. The RDE flow field is a nonuniform mixture of fuel and oxidizer concentrations with strong injector effects, large turbulence effects, multiple shockwaves, and shear layers. These inhomogeneities can lead to significant combustion inefficiencies which have a ...STTR Phase I 2019 National Aeronautics and Space Administration
