Description
The innovation is a low aspect ratio all-lifting configuration for personal air vehicles. This configuration uses an architecture fundamentally different from conventional aircraft to achieve large reductions in cost and improvements in safety. The concept features an integrated all-lifting body that performs the functions of the wing, tail and fuselage of a conventional light airplane with a single, simple structure. The integrated lifting body has an aspect ratio between approximately 1.0 and 2.5, and is deep enough to contain the crew and payload without a conventional fuselage. A further innovation is the use of a faceted shape composed of flat panels. The faceting greatly simplifies the manufacture of the major parts of the airframe, further reducing cost.

The vegetation units on this map were determined through a series of image processing steps including unsupervised classification, ecological modeling and stereoscopic interpretation of aerial photographs supported by field sampling and ecological analysis. The vegetation boundaries were identified on the photographs by means of the photographic signature and collateral information on slope, hydrology, geography, and vegetation in accordance with the Standardized National Vegetation Classification System (October 1995). The mapped vegetation reflects conditions that existed during the specific year and season that the aerial photographs were taken. There is a margin of error inherent in the use of aerial photographs. Therefore, a detailed ground and historical analysis of a single site may result in a revision of the vegetation alliance boundaries established through photographic interpretation.

For maintaining U.S. leadership role in space exploration, there is an urgent need to develop non-flammable shirts, shorts, sweaters, and jackets without compromising the comfort and flexibility of the fabrics. InnoSense LLC (ISL) proposes to utilize its phosphorus-containing ionic polymers in crew clothing. In Phase I, this project would demonstrate flame retardancy and perform standard tests showing adequate comfort, appearance, durability, and non-toxicity, which can be realized from ISL polymers. The overall goal is to take existing fabrics, with their desirable physical properties and high level of comfort, and inserting flame retardancy. The innovations of the proposed approach will offer durability of the treated fabric since the polymers will be covalently bonded to the fabrics. Phase I evaluation will also include biocompatibility of the treated fabrics. Fine-tuning and process scale up will be accomplished in Phase II.

NextGen Aeronautics, Inc. proposes the development of the innovative use of morphing structures for maneuver and flight control as a project for NASA?s Revolutionary Flight Concepts (Topic A7.02). Although aircraft morphing for mission performance enhancement is currently receiving much attention from the research community, there is not a great emphasis on utilizing the same technology for flight control. NextGen, with its extensive experience in smart structures, smart actuation and aircraft morphing has a unique combination of skills and background to develop the proposed concept. NextGen has proposed a morphing fan wing concept as the platform for this project, based upon well-understood flight characteristics and apparent ease of integration. Asymmetric deployment of the fan wing will be utilized to effect roll control of the aircraft. NextGen intends to verify the feasibility of this concept in Phase I, with an eventual flight test planned for Phase II. NextGen will address the critical issues involved with this concept (structures, actuation, skin technology, etc.) in bringing the technology to maturation.

Notice: If you are having difficulties subsetting SNODAS data via Polaris, please contact nsidc@nsidc.org. This data set contains output from the NOAA National Weather Service's National Operational Hydrologic Remote Sensing Center (NOHRSC) SNOw Data Assimilation System (SNODAS). SNODAS is a modeling and data assimilation system developed by NOHRSC to provide the best possible estimates of snow cover and associated parameters to support hydrologic modeling and analysis. The aim of SNODAS is to provide a physically consistent framework to integrate snow data from satellite, airborne platforms, and ground stations with model estimates of snow cover (Carroll et al. 2001). SNODAS includes procedures to ingest and downscale output from the Numerical Weather Prediction (NWP) models, and to simulate snowcover using a physically based, spatially-distributed energy- and mass-balance snow model. SNODAS also includes procedures to assimilate satellite-derived, airborne, and ground-based observations of snow covered area and Snow Water Equivalent (SWE).These data are not suitable for snow fall events or totals for specific regions. For snow fall data, please see the state climatology reports for a particular state. These are gridded data sets for the continental United States at 1 km spatial resolution and 24 hour temporal resolution. Data are stored in flat binary 16-bit signed integer big-endian format with header and metadata files, and are available from 1 October 2003 to present via FTP.

Purpose: The Pavement Testing Facility uses rapid pavement testing of full-scale structures to develop and verify new specifications, designs, and test procedures for rigid and flexible pavements. The facility is used by pavement and highway research engineers to evaluate the durability of both new and existing pavement materials and to help develop smoother and more cost-effective highway systems. Laboratory Description: The facility simulates truck traffic with controlled loading and pavement temperatures. In only a few months, the facility's loading machines can apply wheel loads corresponding to many years of service and collect the corresponding pavement distress and performance data. Two machines allow simultaneous testing of two pavement lanes under the same ambient temperature and moisture conditions or at the same pavement age. Laboratory Capabilities:Thirty-five thousand simulated axle passes can be applied per week, and the wheel load can be varied from 33 kN (7,500 lb) representing a light truck to 84 kN (19,000 lb) for simulating a heavily loaded vehicle. The wheels feature programmable lateral wander, and the tire configurations can be interchanged, such as standard dual or super single. The wheel speed can be varied up to 18 km/hr (11 mi/hr). Radiant heaters are used to control the pavement temperature; temperatures as high at 74 °C can be generated to accelerate asphalt rutting and during the fall, spring, and winter, the heaters are used to maintain an intermediate ambient temperature. Each full-scale test lane is 50 m by 4 m (165 feet by 14 feet), which can be further subdivided into 4 sites for a total of 48 test locations on the facility grounds. A supplemental three-cell test pit and reaction frame allows the water table to be controlled with additional flexibility in testing for unbound pavement layers and other pavement structures. Laboratory Equipment: Twelve full-scale pavement test lanes, two Accelerated Loading Facility machines, a falling weight deflectometer and portable seismic pavement analyzer (PSPA) used for nondestructive pavement testing, dynamic cone penetrometer, instruments, sensors and equipment to measure load-associated pavement response (stress, strain, and deformation), pavement performance distress measurements (rut depth, cracking severity and extent, and roughness), and environmental effects (temperature and moisture), which include a state-of-the-art multichannel data acquisition system to collect pavement instrumentation response data, electronic temperature control and data acquisition to show and record pavement temperatures at various locations in real time, a semiautomatic laser surface profiler to measure both transverse and longitudinal pavement surface profiles, a layer deformation measuring system to monitor vertical compressive strain and rutting in each layer of pavement, computer workstations and software to perform advanced pavement analysis and material modeling, as well as mechanistic design, and relational databases developed to provide customers with a variety of data from pavement-testing experiments, especially pavement response and performance data.
