Abstract:Moller International (MI), the parent company of Aerobotics Inc. (AI), has been developing VTOl manned and unmanned aerial vehicles, called aerobots, for many years. The first electric aerobot used a 36 inch saucer-shaped composite airframe with four vertical ducts, each housing a small electric… more
Abstract:FROM SPOT WELDING TO SOLDERING, JOINING METAL WIRES TO ONE ANOTHER OR TO SUBSTRATES IS A MAJOR PART OF THE ASSEMBLY PROCESS FOR ELECTRICAL AND ELECTRONIC DEVICES. THIS PROGRAM IS DEVELOPING AN ENTIRELY NEW METHOD FOR WELDING SUCH JOINTS USING FILLER METALS. IN THIS NOVEL METHOD, 50-500 MUM DIAM… more
Abstract:Soldering electronic components to circuit boards involves using environmentally harmful cleaning agents and toxic heavy metals like lead. Solder joints can be unreliable in high shock environments because of non-uniform adhesion. This program will develop an entirely new method for welding such… more
Abstract:Infrared absorption, using tunable diode lasers from aircraft and balloon platforms measures stratospheric trace gas. The goal of this project is to develop a new open-path absorption cell suitable for in situ measurements of reactive trace species from an aircraft platform. The open-path design, in… more
Abstract:Nighttime operations are very attractive for the U.S. Armed Forces since these conditions generally maximize their advantage over the opposing forces. The deployment of IR countermeasures to protect aircraft from heat-seeking missiles, however, may remove the advantage of nighttime conditions and… more
Abstract:FERROELECTRIC SELF-ASSEMBLED MONOLAYERS ARE BEING CREATED BY CHEMICALLY MODIFYING MONOLAYERS OF ADSORBED N-ALKANETHIOLS IN VACUUM. THE SURFACE POTENTIALS OF THE RESULTING THIN FILMS ARE MEASURED AS A FUNCTION OF TEMPERATURE AND PYROELECTRIC COEFFICIENTS AND FIGURES OF MERIT FOR THE MODIFIED FILMS… more
Abstract:NASA space flight equipment test facilities require a monitoring device for airborne vapors of the rocket fuels hydrazine, monomethylhydrazine (MMH) and unsymmetrical dimethylhydrazine (UDMH). The ideal monitor will be portable, respond rapidly and specifically to hydrazines, and be sensitive at the… more
Abstract:ANALYSIS OF THE STABLE ISOTOPES IN ATMOSPHERIC METHANE SAMPLES CAN BE USED TO IDENTIFY LOCAL SOURCES AND TO DEFINE THE GLOBAL BUDGET OF THIS RADIATIVELY IMPORTANT GREENHOUSE GAS. THE PROJECT IS DEVELOPING A PORTABLE AND LESS EXPENSIVE ALTERNATIVE TO ISOTOPE MASS SPECTROMETRY FOR MEASURING (13)CH4… more
Abstract:The objectiwe of this proposal is to develop a versatile, inexpensive, and portable spectroscopic probe to quantify the atmospheric corrosion of metal surfaces on aircraft. Since many metals form insoluble salts as products of corrosion reactions, it should be possible to monitor the extent of metal… more
Abstract:Relational Geometric Synthese (RGS) is a new object-oriented paradigm for 3-D geometric design. In RGS-based design, many qualitative and quantitative relationships between geometric objects are captured in a way that permits automatic update, preserving these relationships, following changes in… more
Abstract:Degraded performance due to surface damage of aircraft windows and antennas caused by atmospheric particle effects is currently a very serious problem. Impact testing is currently underway in ground test cells such as the wind tunnels and arc facilities located at Arnold Engineering Development… more
Abstract:The development of fire protection and explosion suppression systems is of critical importance to the safety of both military and civilian aircraft. The phase out of Halon-based fire suppression systems has created a critical need for a compact, light weight, and effective alternative for use in… more
Abstract:A FEASIBILITY STUDY OF A NOVEL ATOMIZER AND ITS ATOMIZATION PROCESS FOR OIL-FIRED BURNER COMBUSTION APPLICATION IS BEING CARRIED OUT. THE ATOMIZER USES THE EFFERVESCENT ATOMIZATION PROCESS TO ACHIEVE GOOD ATOMIZATION WITH A SMALL AMOUNT OF AIR. THE RESEARCH PROGRAM INCLUDES THE FOLLOWING EFFORTS:… more
Abstract:An innovative Microwave-Powered Plasma Thruster concept for On-Orbit application is proposed based on its significant ISP magnitude advantages over the electric arcjet thrusters attained by reduction of inherent arcjet energy losses resulting as a consequence of the pinch plasma arc used for heating… more
Abstract:The objective of this Phase I research is to implement a conservative method for transferring data across arbitrary nonoverlapping zonal interfaces in the CFD code GASP version 3.0. This task will involve a linear interpolation of primitive variables in three dimensions with a gradient weighted flux… more
Abstract:Oil mists from machining operations have long been associated with occupational disease inexposed workers. Concern has increased with recent evidence that exposure to these mists is associatedwith throat, pancreas, rectum, and prostate cancers as well as breathing problems and respiratoryillnesses.… more
Abstract:AN ULTRA LOW-COST FUEL TANKAGE FOR EXPENDABLE TURBOJET PROPULSION SYSTEMS TO BE USED IN THE LONGFOG MISSILE IS PROPOSED. DESIGN CRITERIA AND TECHICAL OBJECTIVES BASED ON MISSION REQUIREMENTS AND COST-EFFECTIVENESS ARE PRESENTED. TWO CANDIDATE SYSTEMS ARE PROPOSED: ONE FEATURING COMPRESSOR DISCHARGE… 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.
