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: 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: 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
SBC: Universal Technology Corporaration Topic: T1204
In this Phase II STTR project, the proposed collaborative effort between UTC, AFIT, and ULRF represents a crucial step forward for AM. UTC’s unique AM optimization and process control framework, constructed entirely from experimental sensor data collected in-situ, will finally transfer technology from our SLM test bed system to state-of-the-art and commercial-grade systems, including a Concept ...STTR Phase II 2017 National Aeronautics and Space Administration
SBC: THE SPACE RESEARCH COMPANY LLC Topic: T603
TSRCo and CU are developing a framework to quantify and predict crew performance in various spacecraft designs in the context of the design process. The framework utilizes an elemental resource breakdown approach to relate the crew, the spacecraft design, and operations. The elements identified in the breakdown correspond to existing measures currently used in the physiological, cognitive, and ps ...STTR Phase I 2017 National Aeronautics and Space Administration
SBC: ADVANCED SPACE LLC Topic: T1102
Distributed Spacecraft Missions (DSMs) such as constellations, formation-flying missions, and fractionated missions provide unique scientific and programmatic benefits. Distributed mission architectures allow for multipoint in-situ measurements, multi-angle viewpoints, and considerably improved understanding of the connections between separately measured phenomena and their time variations. DSMs a ...STTR Phase I 2017 National Aeronautics and Space Administration
SBC: LUNA INNOVATIONS INCORPORATED Topic: T1202
Polymer matrix composites are increasingly replacing traditional metallic materials in NASA launch vehicles. However, the repair and subsequent inspection methods for these materials are considerably more complicated. Typically, a composite laminate patch must be manually fabricated and bonded or co-cured to the damaged structure. To ensure high quality patches with sufficient compaction and l ...STTR Phase I 2017 National Aeronautics and Space Administration
SBC: Tyvak Nano-Satellite Systems, Inc. Topic: T501
Tyvak, in collaboration with UCLA, proposes a novel approach to the challenge of creating a large reflector for Ka-band high data rate links. We propose to attach the primary reflector surface permanently to the surface of a 6U spacecraft and illuminate the reflector using a Cassegrain style subreflector with an illuminating antenna that is permanently mounted to the transmitter / receiver inside ...STTR Phase I 2016 National Aeronautics and Space Administration
SBC: Advanced Systems/Supportability Engineering Technologies And Tools, Inc. Topic: N05149
The S-351 mini-sub is a prototype of the Dry Combat Submersible (DCS). This prototype was established as a means of risk reduction prior to a full commitment to the DCS program. Both of these platforms have an operational need to transit with minimum operator fatigue safely to a pre-defined point and covertly deploy and retrieve SEALS. To meet these operational needs, these platforms require upgra ...STTR Phase II 2017 Department of DefenseSpecial Operations Command
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
Bi-Metallic Additive Manufacturing Close-Out of Coolant Channels for Large Liquid Rocket Engine (LRE) NozzlesSBC: Keystone Synergistic Enterprises, LLC Topic: T1204
This NASA sponsored STTR project will investigate methods for close-out of large, liquid rocket engine nozzle, coolant channels utilizing robotic laser and pulsed-arc additive manufacturing methods. Copper to Nickel alloy interface strength will be quantified and metallurgical characterization completed. A thermal model based on Rosenthal?s analytical expression for a moving heat source, which has ...STTR Phase I 2016 National Aeronautics and Space Administration
