SBC: MICROXACT INC. Topic: T801
Thermoelectric (TE) devices already found a wide range of commercial, military and aerospace applications. However, at present commercially available TE devices typically offer limited heat to electricity conversion efficiencies, well below the fundamental thermodynamic limit, calling for the development of higher efficiency materials. The team of MicroXact Inc., Virginia Tech and Sundew Technolog ...STTR Phase II 2010 National Aeronautics and Space Administration
SBC: Keystone Synergistic Enterprises, LLC Topic: T901
The Keystone and MSU team propose to build on the successful feasibility demonstration conducted during Phase I to complete the development of solid-state joining of high strength and temperature alloys utilizing the Thermal Stir Welding process. The focus alloy for this project is Haynes 230; the alloy of choice typically utilized in rocket engine nozzel skirts. This class of alloy is difficult t ...STTR Phase II 2010 National Aeronautics and Space Administration
SBC: STREAMLINE NUMERICS INC Topic: T901
The innovation proposed here is a high-performance, high-fidelity framework in the computational fluid dynamics (CFD) code called Loci-STREAM to enable accurate, fast and robust simulations of unsteady multiphase flows such as combustion involving liquid-gas phases in liquid rocket injectors and solid-gas phases in solid rocket motors, and cryogenic cavitation in delivery systems of liquid rocket ...STTR Phase II 2010 National Aeronautics and Space Administration
SBC: Plasma Processes, LLC Topic: T301
Small and micro-spacecrafts require the efficient, micro-propulsion systems. Chemical micro-propulsion is best suited for use as primary thrust, orbital insertion and attitude control because of its high energy density. When grouped into arrays for larger thrust applications, micro-propulsion devices provide high propulsive flexibility or can be used as igniters. The proposed effort will focus ...STTR Phase I 2010 National Aeronautics and Space Administration
SBC: SCIENTIC INC Topic: T601
The proposed innovation utilizes carbon nanotubes (CNTs) coated with pseudo-capacitive MnO2 material as nano-composite electrode and ionic electrolyte for the construction of ultracapacitors. This novel approach of using nano-structured CNTs architectures provides high surface area of attachment of MnO2 nano-particles to maximize the charge efficiency and power capacity and to reduce series resist ...STTR Phase I 2010 National Aeronautics and Space Administration
SBC: AURORA FLIGHT SCIENCES CORPORATION Topic: T201
The process of aircraft design requires the integration of data from individual analysis of aerodynamic, structural, thermal, and behavioral properties of a flight vehicle. At present, there is no simple way to integrate the results of the analyses early in the design process. Aurora Flight Sciences and the Massachusetts Institute of Technology Aerospace Computational Design Laboratory propose to ...STTR Phase I 2010 National Aeronautics and Space Administration
SBC: Energy Focus, Inc. Topic: T1002
The proposed innovation is the replacement of existing test stand and parking lot fixtures with current SSL LED technology. The replacement fixtures will reduce energy consumption, generate less heat and provide maintenance free operation for over 50,000 hours. An explosion-proof fixture is capable of containing an internal combustion event without allowing flames or hot gasses to escape to the s ...STTR Phase I 2010 National Aeronautics and Space Administration
SBC: NANOSONIC INC. Topic: T601
The objective of this NASA STTR program is to develop single wall carbon nanotube (SWCNT) based ultracapacitors for energy storage devices (ESD) application, using NanoSonic's patented molecular level self-assembly process performed at room temperature. Specifically, we would combine advances in metallic SWCNTs, metal and oxide nanoclusters, and polymeric materials and electrostatic self-assembly ...STTR Phase I 2010 National Aeronautics and Space Administration
SBC: Research South, Inc. Topic: T801
This proposal offers to provide NASA with an automatic mesh generator for the simulation of aerodynamic flows using Reynolds-Averages Navier-Stokes (RANS) models. The tools will be capable of generating high-quality, highly-stretched (anisotropic) grids in boundary layer regions and transition smoothly to inviscid flow regions even in an adaptive context. The objective of the work is to offer a un ...STTR Phase I 2010 National Aeronautics and Space Administration
SBC: Sierra Lobo, Inc. Topic: T1001
The ability to restore large amounts of vented gaseous helium (GHe) at rocket test sites preserves the GHe and reduces operating cost. The used GHe is vented into the atmosphere, is non-recoverable, and costs NASA millions dollars per year. Helium, which is non-renewable and irreplaceable once released into the atmosphere, is continuously consumed by rocket test facilities at NASA centers such a ...STTR Phase I 2010 National Aeronautics and Space Administration
