A data dictionary and additional information is located on the Data Resource Page. Files are refreshed monthly.
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: TDA RESEARCH, INC. Topic: T601
A spacecraft thermal control system must keep the vehicle, avionics and atmosphere (if crewed) within a defined temperature range. Since water is non-toxic and good for heat transport, it is typically used as the coolant that circulates within the crew cabin boundary. This loop then interfaces with another low freeze point fluid, such as ammonia, for transport of heat to a radiator where the tempe ...STTR Phase II 2013 National Aeronautics and Space Administration
SBC: CFD RESEARCH CORPORATION Topic: T403
The liberation of particles induced by rocket plume flow from spacecraft landing on unprepared regolith of the Moon, Mars, and other destinations poses high mission risks for robotic and human exploration activities. This process occurs in a combination of "extreme environments" that combine low gravity, little or no atmosphere, with rocket exhaust gas flow that is supersonic and partially rarefie ...STTR Phase I 2013 National Aeronautics and Space Administration
SBC: NANOSONIC INC. Topic: T901
The NASA Phase I program would develop and demonstrate semiconductor nanomembrane (NM) based flight sensors and arrays on flexible substrates, using SOI (Silicon on Insulator) silicon NM technique in combination with our pioneering HybridsilTM copolymer nanocomposite materials. Specifically, ultrathin nanostructured sensor skins with integrated interconnect elements and electronic devices that can ...STTR Phase I 2013 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
SBC: PRIORIA ROBOTICS HOLDINGS, INC. Topic: T501
The proposed solution exploits recent advances in computer vision to conceive of a single-camera + gyro + accelerometer vision-based navigation solution such that the processing will be lightweight (requiring only a single optical flow sample per frame). Known landmarks (natural or artificial) will have absolute positions known to planetary exploration worker robots. The worker robot can identif ...STTR Phase I 2013 National Aeronautics and Space Administration
SBC: CFD RESEARCH CORPORATION Topic: T101
Launch vehicles experience extreme acoustic loads during liftoff driven by the interaction of rocket plumes and plume-generated acoustic waves with ground structures. Currently employed predictive capabilities to model the complex turbulent plume physics are too dissipative to accurately resolve the propagation of acoustic waves throughout the launch environment. Higher fidelity liftoff acoustic a ...STTR Phase I 2013 National Aeronautics and Space Administration
High Performance Multiphase Combustion Tool Using Level Set-Based Primary Atomization Coupled with Flamelet ModelsSBC: STREAMLINE NUMERICS INC Topic: T101
The innovative methodologies proposed in this STTR Phase 1 project will enhance Loci-STREAM which is a high performance, high fidelity simulation tool already being used at NASA for a variety of CFD applications. This project will address critical needs in order to enable fast and accurate simulations of liquid space propulsion systems (using propellants such as LOX, LCH4, RP-1, LH2, etc.). The pr ...STTR Phase I 2013 National Aeronautics and Space Administration
Closed-Loop Control of the Thermal Stir Welding Process to Enable Rapid Process / Part QualificationSBC: Keystone Synergistic Enterprises, LLC Topic: T901
Thermal Stir Welding (TSW) provides advancement over the more conventional Friction Stir Welding (C-FSW) process because it separates the primary processes variables thereby allowing independent control of metal stirring and forging from the stir zone temperature. However, the feedback for precise control of the stir zone temperature, and hence the process parameters to sustain that temperature wi ...STTR Phase II 2013 National Aeronautics and Space Administration
SBC: STREAMLINE AUTOMATION LLC Topic: T301
Advances in structured heterogeneity together with nanomaterials tailoring has made it possible to create thermoelectrics using high temperature, polymer composites. While such thermoelectrics do not have the capability to approach the efficiency of top performing ceramic modules such as BiTe, they do provide two unique aspects of use in energy scavenging: the ability to cover large areas easily, ...STTR Phase I 2013 National Aeronautics and Space Administration
