Abstract:This proposal addresses full digital control of the Line of Sight (LOS) Stabilization system required for advanced infra-red (IR) seekers employing strap down sensors and inertially stabilized optics, while maintaining the LOS degrees of freedom to supportmissile interceptor requirements.The effort… more
Abstract:60765 Current designs for electric motors use a housing that acts as both a structural support and as a method of cooling the stator and rotor. This approach to cooling is not as effective as possible because heat must flow from the rotor and stator through the housing to the cooling media. … more

Abstract:Future satellite architectures must readily support the on-orbit maintenance and servicing that is vital for maintaining and dynamically reconfiguring both commercial and military satellites during orbital operation. A well-founded architectural designmust also address the need to reduce costs… more
Abstract:The ability to maneuver, change orbits, and rapidly deploy spacecraft is a key requirement for the space user community. However, large and bulky propulsion systems with a significant mass of fuel on board often limit the maneuverability and capabilitiesof space vehicles. AeroAstro is developing… more
Abstract:The specific innovation proposed is to design an advanced composite airframe panel for damage tolerance by incorporating biologic solutions to a similar problem found in nature, using a biomimetic approach. We will identify principal material (fiber) directions and density profiles about naturally… more

Abstract:65821 Aircraft measurements of ammonia and nitric acid can provide critical information on the sources and sinks of these atmospheric nitrogen species. This is important in understanding air quality, aerosol formation, visibility, and the impact of energy production and usage on global climate… more
Abstract:This project concerns the development of a sensor intended to remotely monitor plant stress using active stimulation of plant chlorophyll fluorescence. The intensity and spectral band shape of leaf chlorophyll fluorescence in green plants has been linked to the physiological status of the plants and… more
Abstract:This Small Business Innovation Research Phase I (SBIR) project will develop a new class of real time aerosol mass spectrometers (AMSs) for analysis of respirable powder and liquid aerosol in pulmonary drug delivery systems. Three parameters control the effective delivery of drugs to the lungs: (1)… more
Abstract:This SBIR Phase1 project will involve the development of a novel method of simultaneously measuring multiple trace chemical species in jet engine exhaust, based upon an extension of the technology of tunable diode laser (TDL) spectroscopy. We will develop and demonstrate a new means of combining the… more

Abstract:High pressure ratio compressor operation is enabled by blade cooling, based on an evaporation / condensation cycle. The blade or blisk temperature is defined by the vaporization temperature of a working fluid internal to the blade, with heat transferred to an integral condenser at each blade root.… more
Abstract:This Small Business Innovation Research (SBIR) Phase I project has as its goal the demonstration of the feasibility of an optical alloy analysis instrument based on a microchip laser excitation source. This instrument will determine elemental composition using laser-induced plasma spectroscopy… more
Abstract:60520 The atmospheric abundance of carbon dioxide and methane have increased dramatically during the industrial era. Since these increases can perturb the global climate, it is vital to understand and quantify the factors controlling them. This is difficult because CO2 and CH4 have a wide… more

Abstract:Prevention of catastrophic failure of engine components is a major goal to the subtopic. Catastrophic failures of turbine engines are often caused by vibration-induced compressor and fan blade fatigue fractures. Existing capacitance systems have been unable to accurately measure blade vibration due… more

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
