SBC: POLARONYX INC Topic: T901
Laser transmitters operating at a pulse repetition rate of 20 Hz to 50 Hz and with pulse energy from 30 - 50 mJ have been considered to be an enabling technology for CO2 measurement and optical communications. PolarOnyx proposes a novel approach targeting to make reliable high energy ultra large core fiber amplifier at 1.57 micron and employing our proprietary technologies in specialty fibers, spe ...STTR Phase I 2015 National Aeronautics and Space Administration
SBC: SOUTHWEST SCIENCES INC Topic: T601
Southwest Sciences Inc. (SWS), in collaboration with the Southwest Research Institute (SwRI), will develop a reliable, ultra compact, low power diode laser multigas sensor to measure carbon dioxide (CO2), ammonia (NH3), oxygen (O2) and water vapor (H2O) concentrations in the presence of saturated and condensable water concentrations appropriate for NASA's portable life support system (PLSS). A hig ...STTR Phase I 2015 National Aeronautics and Space Administration
SBC: MESA PHOTONICS LLC Topic: T601
Mesa Photonics, in collaboration with the College of Optics and Photonics (CREOL) at the University of Central Florida, proposes to develop a spacesuit gas sensor based upon its Enhanced Raman Gas Sensor (ERGS) technology. The goal a moisture tolerant, drop-in replacement for the current CO2 sensor. Preliminary work achieved detection sensitivities for CO2, CH4, O2, and N2 of 1000, 300, 1000 and 1 ...STTR Phase I 2015 National Aeronautics and Space Administration
SBC: OPTO-KNOWLEDGE SYSTEMS INC Topic: T801
We propose to develop and demonstrate a new sensor platform for isotope and trace-gas analysis that is appropriate for future planetary missions. Among other applications, the technology can enable the collection of isotope ratio data in support of the search for evidence of life within the solar system. Current limitations to in-situ isotope measurements will be overcome by utilizing a capillar ...STTR Phase II 2015 National Aeronautics and Space Administration
SBC: GLOYER-TAYLOR LABORATORIES INC Topic: T102
GTL has been developing a suite of transformational technologies that have the capability to disrupt the traditional launch vehicle paradigm. BHL composite cryotank technology provides a four times improvement over large aluminum iso-grid tanks, offering a 6 percentage point improvement in small stage PMF. Superior Stability Engine is an innovative liquid rocket engine configured to maximize comb ...STTR Phase II 2015 National Aeronautics and Space Administration
SBC: GLOYER-TAYLOR LABORATORIES INC Topic: T101
The proposed technology builds off GTL's advanced solid ramjet fuel. The method uses additive manufacturing methods to produce an innovative new type of fuel grain that regresses quickly and has a high Isp and combustion efficiency. With this technology, the performance of a liquid rocket engine can be had with a hybrid rocket system. This technology allows for a simple, low cost, high performanc ...STTR Phase I 2015 National Aeronautics and Space Administration
Integrated Reacting Fluid Dynamics and Predictive Materials Degradation Models for Propulsion System ConditionsSBC: CFD RESEARCH CORPORATION Topic: T1202
Computational fluid dynamics (CFD) simulations are routinely used by NASA to optimize the design of propulsion systems. Current methods for CFD modeling rely on general materials properties to determine fluid structure interactions. This introduces uncertainty when modeling extreme conditions, where materials degrade and properties may change as a consequence. This also limits the use of CFD as a ...STTR Phase I 2015 National Aeronautics and Space Administration
SBC: CFD RESEARCH CORPORATION Topic: T602
High-energy space radiation from Galactic Cosmic Rays and Solar Particle Events (SPEs) pose significant risks to equipment and astronaut health in NASA missions. In particular, energetic particles from SPEs associated with flares and coronal mass ejections (CMEs) constitute a highly dynamic and penetrating radiation environment that may adversely affect not only beyond-Low-Earth-Orbit missions, bu ...STTR Phase I 2015 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 process modeling and material property prediction that contribute to slow and costly process development, process qualification and product certification. To address these gaps, CFDRC and our partner Dr. Kevin Chou, University of Alabama, will develop multiple computatio ...STTR Phase II 2015 National Aeronautics and Space Administration
SBC: CHROMOLOGIC LLC Topic: T801
Chromologic (CL) and the California Institute of Technology (Caltech) propose to develop and demonstrate a Multifunctional Environmental Digital Scanning Electron Microprobe (MEDSEM) instrument that transmits high-energy beams of electrons sequentially from a two-dimensional array of miniaturized electron probes into a planetary atmosphere, and these electrons will strike solid or liquid planetary ...STTR Phase I 2015 National Aeronautics and Space Administration
