The SBIR.gov award data files now contain the required fields to calculate award timeliness for individual awards or for an agency or branch. Additional information on calculating award timeliness is available on the Data Resource Page.
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: Gordon Nelson and Associates Topic: T703
Project involves development of new flexible FR polyurethane (PU)insulation foams through a non-toxic environmentally friendly composite approach. Foams have bound-in polymeric phosphonate FRs, with added synergists and smoke suppressants. Such foams will not leach FR. Foams have fine cell structure and excellent flexible foam properties. Cone performance of the identified foam family (368 peak ...STTR Phase II 2013 National Aeronautics and Space Administration
SBC: Sentix Topic: T1502
Sentix and Brigham Young University propose the research and development of embedded payload intelligence for inflight optimization of surveillance, reconnaissance, and scientific missions. The current proposal leverages a substantial body of scientific and experimental knowledge derived from the Tactical Seeability System developed by Sentix' staff and BYU researchers to provide fully automated ...STTR Phase I 2013 National Aeronautics and Space Administration
Metal Digital Direct Manufacturing (MDDM) for Close-Out of Combustion Chambers and Nozzle FabricationsSBC: Keystone Synergistic Enterprises, LLC Topic: T1204
This NASA sponsored STTR project will investigate methods for close-out of large, liquid rocket engine, nickel or stainless steel nozzle, coolant channels utilizing robotic laser and pulsed-arc additive manufacturing (AM)methods. Structural jacket to coolant channel land area interface strength will be quantified and metallurgical characterization completed. Process optimizations will be conducte ...STTR Phase II 2017 National Aeronautics and Space Administration
SBC: VOXTEL, INC. Topic: T901
One of the challenges facing missions to other planetary bodies including Earth's Moon, Mars, Venus, Titan, Europa; and proximity operations (including sampling and landing) on small bodies such as asteroids and comets' is the ability to provide accurate altimetry for descent, then assess safe landing sites by surveying the landscape. To address NASA's need for space-hardened planetary entry, desc ...STTR Phase I 2016 National Aeronautics and Space Administration
SBC: Advratech Topic: T1204
In this Phase I STTR project, pursuant to the Materials Genome Initiative (MGI) and Integrated Computational Materials Engineering (ICME) interests, the proposed collaborative effort between WSU and Advratech will represent the first AM optimization framework of its kind, constructed entirely from experimental sensor data collected in-situ. Rather than using in-process data to inform limited "phy ...STTR Phase I 2016 National Aeronautics and Space Administration
