The tiltwing class of aircraft consists of vehicles with the ability to rotate the wing and propulsion system as a unit a full 90 degrees from the standard fixed wing configuration to one in which the wing and thrust axis become perpendicular to the body axis. This thrust vectoring capability allows the aircraft to utilize thrust borne flight for vertical takeoff and landing as well as the convent ...STTR Phase I 2017 National Aeronautics and Space Administration
SBC: Luna Innovations Incorporated Topic: T802
Luna will team with Dr. John Bowers of UCSB to develop an Optical Frequency Domain Reflectometry (OFDR) system-on-chip using heterogeneous silicon photonics to enable a minimal weight structural health monitoring system. This system-on-chip will be the building block for distributed sensing interrogation systems that are the size of a deck of playing cards. This lightweight, rugged, and miniature ...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: LASER & PLASMA TECHNOLOGIES LLC Topic: T801
Laser & Plasma Technologies (LPT), teamed with the National Science Foundation (NSF) Center for Lasers at the University of Virginia (UVA), proposes an advanced optical fiber coupled hybrid spectroscope for in situ characterization of organic compounds. The proposed approach provides information on organic compounds by analyzing spectra obtained from Laser Induced Breakdown Spectroscopy (LIBS) an ...STTR Phase I 2017 National Aeronautics and Space Administration
SBC: Terves LLC Topic: T101
The Phase I STTR project will develop an ignition system for a high density hybrid rocket motor using non-toxic, storable, ionic liquid oxidizers and high density polymer fuels. The program will also research fuel additives to boost ISP and fuel regression rate of the high density, high regression ate fuel.. This high density propulsion system resolves one of the chief drawbacks of hybrid rock ...STTR Phase I 2017 National Aeronautics and Space Administration
SBC: Faraday Technology, Inc. Topic: T601
Among the numerous technological advances sought in order to facilitate human space travel, solutions and innovations are needed for techniques that supports the mass- and energy-efficient maintenance of closed air, water, and waste systems in spacecraft habitats that operate within microgravity. As missions are foreseen to be extended with limited earth resupply available there is need to develop ...STTR Phase I 2017 National Aeronautics and Space Administration
SBC: CFD RESEARCH CORPORATION Topic: T102
Launch vehicles experience extreme acoustic loads dominated by rocket exhaust plume interactions with ground structures during lift-off, which can produce damaging vibro-acoustic loads on the vehicle and payloads if not properly understood and mitigated against. Existing capabilities for modeling the turbulent plume physics during early lift-off are too dissipative to accurately resolve the propag ...STTR Phase I 2017 National Aeronautics and Space Administration
SBC: CFD RESEARCH CORPORATION Topic: T102
Solid rocket motor (SRM) design requires thorough understanding of the slag accumulation process in order to: predict thrust continuity, optimize propellant conversion efficiency, predict coning effects from sloshing, and assess potential orbital debris (slag) hazard. Current state-of-the-art models for SRM environment do not have the capability to simulate the accumulation and dynamics of slag in ...STTR Phase I 2017 National Aeronautics and Space Administration
SBC: CFD RESEARCH CORPORATION Topic: T1204
Despite the rapid commercialization of additive manufacturing technology such as selective laser melting, SLM, there are gaps in models for material microstructure and property prediction that slow qualification and certification. Improvements in coupling microstructure prediction models to local process conditions, validation, and control of material microstructure are required to mature the stat ...STTR Phase I 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
