Description

The proposed SBIR Phase II program will lead to the validation of a state-of-the-art Large Eddy Simulation (LES) model, coupled with a Ffowcs-Williams-Hawkings (FW-H) farfield acoustic solver, for supporting the development of advanced engine concepts, including innovative flow control strategies for attenuation of their jet noise emissions. During Phase I, the LES/FW-H model was validated against matched sets of flowfield and companion acoustic data acquired at NASA/GRC for round nozzles. The flowfield validation included detailed comparisons against imagery, mean flow measurements and turbulence statistics. During Phase II, the end-to-end LES/FW-H noise prediction model will be demonstrated and validated by applying it to high aspect-ratio rectangular nozzle designs, proposed for testing at NASA GRC under the Fundamental Aeronautics Program. The model will also be validated against acoustic and flowfield data from a realistic jet-pylon experiment, thereby significantly advancing the state-of-the-art for LES. This critical validation will provide the foundation for proceeding to application of this innovative methodology in supporting the design and optimization of control concepts, e.g. chevrons, bevels, etc., as well as ultimately performing predictions of noise emissions from full-scale, realistic nozzles with complex exhaust flowpaths, airframe/propulsive jet interactions, etc.

Description

Color infrared (CIR) aerial photographs were acquired to compliment another set of aerial photos used to produce vegetation spatial database coverages of Effigy Mounds National Monument (EFMO) and environs. Aerial photos were collected on August 25, 2000 at a scale of 1:15,000 to capture peak vegetation biomass. The U.S. Geological Survey (USGS) Upper Midwest Environmental Sciences Center (UMESC) of La Crosse, Wisconsin has produced spatially referenced aerial photo mosaic images of the aerial photographs for both the Yellow River and Sny Magill units and their environs. The photo mosaics are raster datasets compressed with MrSID (LizardTech), projected in Universal Transverse Mercator (UTM), Zone 15, using the North American Datum of 1983 (NAD83).

Description

Monthly Weather Observations (Form 1001) is a set of historical manuscript records for the period 1893-1948. In order to fill in the observation gap prior to the time when commercial aviation began in the U.S., NCDC Climate Data Modernization Program (CDMP) retrieved surface observations taken two to four times daily beginning as early as 1893 at the City Weather Bureau Offices. Through 1936 observations were taken twice daily; then in 1937 the general practice was to record four observations per day. The data elements are as follows: station pressure, sea level pressure, dry and wet bulb temperature, dew point, maximum and minimum temperature, wind direction and speed, precipitation, cloud amount and type, ceiling, state of weather and visibility. It should be noted that not all elements are present for all stations in this dataset, and that ceiling and visibility observations did not begin at the city offices until the 1930's. Official surface weather observation standards can be found in the Circular N manuals.

Description

Joint Polar Satellite System (JPSS), starting with S-NPP launched on 28 October 2011, is the new generation of the US Polar Operational Environmental Satellites (POES). As during the POES era, NOAA is responsible for all JPSS products, including Level 2 Visible Infrared Imaging Radiometer Suite (VIIRS) SST derived using NOAA heritage Advanced Clear-Sky Processor for Ocean (ACSPO) system at the native sensor resolution. VIIRS is a whiskbroom scanning radiometer which takes measurements in the cross-track direction within a field of regard of 112.56 degrees, using 16 detectors and double-side mirror assembly. At a nominal altitude of 829 km, the swath width is 3060 km, providing full daily coverage both in the day and night side of the Earth. VIIRS has 22 spectral bands covering the spectrum from 0.4-12 micrometers, including 16 moderate resolution bands (M-bands). In addition to pixel-level earth locations, Sun-Sensor geometry, and ancillary data from NCEP global weather forecast, ACSPO inputs are 3 brightness temperatures (BTs) in M12 (3.7microns), M15 (11microns), and M16 (12microns), and 2 reflectances in M5 (0.67microns) and M7 (0.87microns) bands, used for cloud identification. ACSPO output files are in netcdf4 format compliant with the GHRSST Data Specification version 2 (GDS2). Each output file (granule) contains 10 minutes of data. In each valid water pixel (defined as ocean, sea, lake or river, up to 5 km inland; fill values are reported in invalid pixels, at >5 km inland), the following layers are reported, among others: BTs in M12, 15, and 16 (original radiances are included for those users interested in direct radiance assimilation, e.g., NOAA NCEP, NASA GMAO); SSTs derived from BTs using multi-channel SST (MCSST; night) and Non-Linear SST (NLSST; day) algorithms (Petrenko et al., 2014); and ACSPO clear-sky mask (ACSM; provided in each pixel as part of l2p_flags) (Petrenko et al., 2010). We only recommend using the ACSM confidently clear pixels (equivalent to GDS2 quality level=5, also reported for each pixel). The ACSM also provides day/night, land, ice, twilight, and glint flags. Note that users of ACSPO data have the flexibility to ignore the ACSM, derive their own clear-sky mask, and use BTs and SSTs in those pixels. They may also ignore ACSPO SST, and derive their own SST from the original BTs. ACSPO VIIRS products are monitored and validated against in situ data (Xu and Ignatov, 2014) in SQUAM (Dash et al, 2010) and MICROS (Liang and Ignatov, 2011).

Description

During the Phase II Lunar Health Monitor program, Orbital Research will develop a second generation wearable sensor suite for astronaut physiologic monitoring. The low profile system will be appropriate for both Extravehicular activities (EVA) and Intravehicular activities (IVA) monitoring scenarios. The EVA and IVA wearable platforms are capable of monitoring a complete physiologic profile of overall astronaut health status. Sensors of respiration, body temperature, acceleration and cardiac data are included. Inclusive in this sensor suite is Orbital's FDA cleared and patented dry recording electrodes. The sensors are held to the body via the garment and function without any tapes, adhesives or gels. The sensors are mechanically connected to the sensor suite. The mechanical connections allow sensors to be semi-permanently interfaced with either the EVA or IVA designs. These connectors allow sensors to be added, removed or replaced based on monitor application or anatomical constraints. The Lunar Health Monitor is designed to be continuously worn serving as a safety mechanism for out of vehicle exploration missions and a monitoring device for applications such as in orbit fitness assessment. The Lunar Health Monitor is easy to don and doff and non-encumbering to routine and functional tasks.

Description

The proposed innovation will dramatically improve the performance of tritium-powered betavoltaic batteries through the development of a high-aspect ratio, expanded surface area p/n junction composed of indium gallium phosphide. The enhanced surface area features will be built using reactive ion etch (RIE) modified germanium substrates via metalorganic chemical vapor deposition (MOCVD). The proposed 3-dimensional betavoltaic p/n junction will provide a cost saving of up to 90%, while increasing energy density to up to ten times that of lithium batteries. Such an advanced semiconductor device will produce much higher power outputs than are possible with existing state-of-the-art devices. It will provide the battery a life span in excess of 20 years with the broad-range temperature-insensitivity benefits normally associated with betavoltaics. This increased power/energy density for tritium betavoltaics will open up pathways for significant advances in power solutions for diminutive sized, low-power microelectronic devices that may be used in Cubesat and in-space power systems. Example applications include microwatt-to-milliwatt autonomous 20+ year sensors/microelectronics for use in structural monitoring, mesh networks, tagging and tracking wireless sensors, medical device implants, and deep space power where solar is not easily available. Tritium betavoltaics are capable of addressing this power niche for devices requiring reliable, uninterrupted power through extremes of temperature, longevity and diminutive form factors where traditional batteries cannot operate.
