The Award database is continually updated throughout the year. As a result, data for FY24 is not expected to be complete until March, 2025.

Download all SBIR.gov award data either with award abstracts (290MB) or without award abstracts (65MB). 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.

  1. Multi-Robot Planetary Exploration Architectures

    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 ...

  2. High-Fidelity Gas and Granular Flow Physics Models for Rocket Exhaust Interaction with Lunar Soil

    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 ...

  3. Ultraefficient Themoelectric Devices

    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 ...

  4. Thermal Stir Welding of High Strength and High Temperature Alloys for Aerospace Applications

    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 ...

  5. A Self-Regulating Freezable Heat Exchanger for Spacecraft

    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 ...

  6. New Flexible FR Polyurethane Foams for Energy Absorption Applications

    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 ...

  7. Closed-Loop Control of the Thermal Stir Welding Process to Enable Rapid Process / Part Qualification

    SBC: 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 ...

  8. Metal Digital Direct Manufacturing (MDDM) for Close-Out of Combustion Chambers and Nozzle Fabrications

    SBC: 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 ...

  9. Highly Sensitive Flash LADAR Camera

    SBC: VOXTEL, INC.            Topic: T901

    To address the urgent need for 3D flash-lidar technology for landing on solar system bodies and for spacecraft rendezvous and docking with satellites, an effort is proposed to fabricate, characterize, and test a versatile, high-sensitivity InGaAs APD 3D flash lidar and to advance the technology-readiness level (TRL) of lidar technologies suitable for NASA mission requirements. Leveraging an existi ...

  10. Modified Acoustic Emission for Prognostic Health Monitoring

    SBC: Prime Photonics, LC            Topic: T1201

    Prime Photonics proposes to team with Dr. Duke of Virginia Tech to develop a multi-mode, enhanced piezoelectric acoustic emission sensing system to couple large damage events to local distribution of damage accommodation. Our system will be centered around an instrument designed to accept the output of a piezoelectric transducer sensitive to in-plane acoustic events. The signal processing path w ...
