SBC: AURORA FLIGHT SCIENCES CORPORATION Topic: T101
Space policy direction is shifting, particularly with respect to human goals. Given the uncertainty of future missions to the moon, Mars, and other bodies, a tool that allows for informed analysis of the option space is particularly relevant. Aurora Flight Sciences and MIT propose to further develop the Multi-Robot Planetary Exploration Architecture (MRPEA) methodology, a suite of software tools ...STTR Phase II 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: 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: 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: 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
SBC: Skyre, Inc. Topic: T1001
Liquid hydrogen is used extensively by NASA to support cryogenic rocket testing. In addition, there are many commercial applications in which delivery and use of cryogenic hydrogen is more economical than gaseous hydrogen. Unfortunately, loss of hydrogen resulting from boiloff can both increase the cost of the end product and create safety concerns. Sustainable Innovations and its teammates, Th ...STTR Phase I 2010 National Aeronautics and Space Administration
SBC: TECH-X CORPORATION Topic: T301
Computational tools that accurately predict the performance of electric propulsion devices are highly desirable by NASA and the broader electric propulsion community. Large investments in running the long duration test programs (> 20 kHrs) at NASA GRC can be reduced with computer models and allow more focus on exploring the NEXT ion thruster design for future space missions. The current state of e ...STTR Phase I 2010 National Aeronautics and Space Administration
SBC: CFD RESEARCH CORPORATION Topic: T701
Current modeling of Lunar and Martian soil erosion and debris transport caused by rocket plume impingement lacks essential physics from the peculiar granular characteristics of highly irregular regolith particles. Current granular mechanics models are based on mono-disperse spherical particles empiricism unsuitable for capturing the poly-disperse irregularly shaped grain mechanics. CFDRC and the U ...STTR Phase II 2010 National Aeronautics and Space Administration
