Description
NASA has determined that it requires extremely durable, high-performance, low cost engines to meet future multi-use in-space, non-toxic, cryogenic propulsion requirements such as orbit transfer, descent, ascent and pulsing attitude control. Transpiration-cooling technology has long been considered a candidate for long-life thrust chambers but has never been deployed on a domestic rocket engine. In this program WASK Engineering, Inc. demonstrates methane transpiration cooling of an oxygen/methane thrust chamber at 260 psia chamber pressure and a range of mixture ratios up to 3.2 O/F in a 65 lbf engine assembly. Key tasks are the design and fabrication of a transpiration-cooled chamber spool section that integrates into existing hardware from an on-going USAF program and then hot fire testing it in the existing test stand. Post-test data analyses are used to anchor and refine thermal and performance algorithms in transpiration cooling models that then validate, or invalidate, transpiration cooled thrust chambers for this set of requirements.

High Energy, Low Temperature Gelled Bi-Propellant Formulation for Long-Duration In-Space Propulsion Project
Published By National Aeronautics and Space Administration
Issued about 9 years ago
Summary
Description
The use of gelled propellants for deep space planetary missions may enable adoption of high performance (Isp-vac>360 sec) propellant combinations that do not require power-intensive heating and stirring cycles before firings, and whose handling and safety characteristics are close to stated goals of "green" propellants. Phase I focused on the ability to gel both halves of the propellant combination of liquid propane and MON-30 (GLP/GMON-30). This combination was selected to provide extended low-temperature capability. Both components were successfully gelled and preliminary rheological data was taken. To allow system-wide studies of the impact of gelled propellant adoption, non-Newtonian gel rheology models were added to NASA's flow network system analysis code, Generalized Fluid System Simulation Program (GFSSP). These models were validated with experimental gel data. Preliminary two-fluid CFD simulations were performed to understand the flow of gelled propellants in microgravity environments. Phase II will culminate in a hot-fire demonstration of a GLP/GMON-30 rocket chamber, to be performed at AMRDEC facilities. To support this, hardware for gelling of the propellants will be fabricated and delivered to NASA. Suitable quantities of the gelled propellants will be prepared and fundamental data, including rheological and freezing point behavior will be determined. Expanded system-level assessments will be performed, using both GFSSP and CFD tools.

Summary
Description
This dataset contains a GeoTIFF with 2x2 meter cell size representing the rugosity of site WOO216, a selected area of seafloor south of St. Thomas, USVI, derived from data collected in March and April 2011. NOAA's NOS/NCCOS/CCMA Biogeography Branch, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data south of St. Thomas and St. John, USVI, from 3/28/2011 to 4/14/2011. Data was acquired with a moon pool flange-mounted Reson 7125 multibeam echosounder (dual frequecy, 200/400 kHz) for water depths of up to 75 meters. It was processed by a NOAA contractor using CARIS HIPS software. Data has all correctors applied (attitude, sound velocity) and has been reduced to mean lower low water (MLLW) using final approved tides and zoning from NOAA COOPS. Data is in UTM zone 20 north, datum NAD83. The processed CARIS data was used to generate a CARIS BASE surface based on CUBE. A BAG file was exported from the BASE surface, and converted to a GeoTIFF in ESRI ArcMap 10. Rugosity was derived from this surface using NOAA’s Benthic Terrain Modeler extension. The project was conducted to meet IHO Order 1 and 2 accuracy standards, dependant on the project area and depth. All users should individually evaluate the suitability of this data according to their own needs and standards.

NOAA's Gulf of the Farallones National Marine Sanctuary (GFNMS) Beach Watch Program, administered by the Farallones Marine Sanctuary Association (FMSA), is a long-term monitoring program operating within GFNMS and NOAA's Monterey Bay National Marine Sanctuary along the California coast. An objective of the program is to develop baseline information on the organisms inhabiting the sanctuaries and on the physical characteristics of the sanctuaries. To achieve this objective, Beach Watch volunteers have taken photographic slides of animals (both alive and dead) and beach profiles during surveys of over fifty sanctuary beaches every two to four weeks since 1993. As part of a "data rescue" effort, GFNMS, FMSA, and NOAA's National Oceanographic Data Center and Climate Database Modernization Program have sponsored a project to scan Beach Watch's photographic slides and create high-resolution TIFF and Web-accessible JPEG images for the public. This collection is part of the project, which Jan Roletto of GFNMS coordinated for FMSA, and it contains images from surveys of Half Moon Bay, Naples Beach (segment 4-03), California from 1996-09-18 to 1998-05-28.

Description
Hydrographic and Impairment Statistics (HIS) is a National Park Service (NPS) Water Resources Division (WRD) project established to track certain goals created in response to the Government Performance and Results Act of 1993 (GPRA). One water resources management goal established by the Department of the Interior under GRPA requires NPS to track the percent of its managed surface waters that are meeting Clean Water Act (CWA) water quality standards. This goal requires an accurate inventory that spatially quantifies the surface water hydrography that each bureau manages and a procedure to determine and track which waterbodies are or are not meeting water quality standards as outlined by Section 303(d) of the CWA. This project helps meet this DOI GRPA goal by inventorying and monitoring in a geographic information system for the NPS: (1) CWA 303(d) quality impaired waters and causes; (2) hydrographic statistics based on the United States Geological Survey (USGS) National Hydrography Dataset (NHD); and (3) special designations recognizing waters of exceptional quality as defined in State water quality standards. Hydrographic and 303(d) impairment statistics were evaluated based on a combination of 1:24,000 (NHD) and finer scale data (frequently provided by state GIS layers). Information on State-designated uses and waters of exceptional quality are only available for a limited number of parks at this time.

NOAA's National Geophysical Data Center (NGDC) is building high-resolution digital elevation models (DEMs) to support individual coastal States as part of the National Tsunami Hazard Mitigation Program's (NTHMP) efforts to improve community preparedness and hazard mitigation. These integrated bathymetric-topographic DEMs are used to support tsunami and coastal inundation mapping. Bathymetric, topographic, and shoreline data used in DEM compilation are obtained from various sources, including NGDC, the U.S. National Ocean Service (NOS), the U.S. Geological Survey (USGS), the U.S. Army Corps of Engineers (USACE), the Federal Emergency Management Agency (FEMA), and other federal, state, and local government agencies, academic institutions, and private companies. DEMs are referenced to various vertical and horizontal datums depending on the specific modeling requirements of each State. For specific datum information on each DEM, refer to the appropriate DEM documentation. Cell sizes also vary depending on the specification required by modelers in each State, but typically range from 8/15 arc-second (~16 meters) to 8 arc-seconds (~240 meters).

This SBIR proposal aims to develop thermal energy storage heat exchangers that are significantly lighter and higher conductance than the present art which involves significant metal weight. We aim to use carbon fiber for conductive and convective heat transfer enhancements and replace metal with novel carbon-polymer composites. The concept materials can be configured to serve a broad range of thermal management applications for NASA, in particular thermal storage heat exchangers. Phase 1 will gather NASA requirements for near term systems involving active cooling with single- and two-phase loops passive cooling with heat pipes. In particular the Constellation program and the Orion vehicle will be considered to assess the potential benefits of the proposed materials approach. Initial fabrication and characterization of the materials concept will be performed. Design options for Phase 2 development units will be prepared.
