Abstract:1This proposal describes a program to design a regenerable gas generator system which can be used safely aboard submarines. We propose to investigate a number of possible techniques using all liquid, all solid or combined liquid/solid fuel/oxidizer combinations. One candidate system which looks very… more
Abstract:A proof-of-concept prototype of a new type of pulsed plasma thruster with a specific impulse of 3000s will be built. Based upon a recently developed plasma source, the "X-line thruster" concept operates by inductively driving an electrodeless discharge in a small volume of gas, and then accelerating… more
Abstract:THE OBJECT OF THIS PROPOSED RESEARCH IS TO PRODUCE MORE RELIABLE ESTIMATES OF EXTREME WINDS IN THE UNITED STATES BY SEPARATELY ANALYZING WINDS DUE TO THUNDERSTORMS AND LARGE SCALE EXTRATROPICAL STORMS. THE PRESENT STATE OF THE ART METHODS FOR ESTIMATING DESIGN WIND SPEEDS IN NON-HURRICANE REGIONS OF… more
Abstract:THE CENTRAL POSTULATE OF THE PROPOSED EFFORT IS THAT WEAPONS WILL SENSE THEIR IMPACT CONDITIONS; I.E. TRAJECTORY ANGLE, ANGLE OF ATTACK (AOA), ROTATION VELOCITY, AND VELOCITY IN RELATION TO THE TARGET SURFACE. IF THOSE CONDITIONS ARE LESS THAN BENEFICIAL FOR PENETRATOR SURVIVABILITY AND/OR… more
Abstract:THE AIM OF THIS PROJECT IS TO EVALUATE THE USE OF FOURIER TRANSFORM INFRARED (FTIR) EMISSION SPECTROSCOPY FOR CHARACTERIZING THE DIAMOND THIN FILM DEPOSITION PROCESS WITH IN SITU MEASUREMENTS. AN FTIR SPECTROMETER WILL BE INSTALLED ON A COMMERCIALLY-AVAILABLE DIAMOND REACTOR TO RECORD THE INFRARED… more
Abstract:THIS PROJECT WOULD DEVELOP AN ECR SPUTTER SOURCE FOR METAL OXIDE THIN FILM DEPOSITION EMPLOYING SOLID METAL OXIDE TARGETS AS A MATERIAL SOURCE. IN PHASE I, YBCO WILL BE USEDAS THE SPECIFIC METAL OXIDE IN ORDER TO EVALUATE AND ELIMINATE THE EFFECTS OF FILM DAMAGE BY ENERGETIC PARTICLE BOMBARDMENT… more
Abstract:This Phase I SBIR will investigate the feasibility of producing reliabMICONDUCTOR, MICROWAVE AND MICROELECTRONIC DEVICES ARE DRIVING THERMALle High-Resolution Satellite Cloud Climatologies (HRSCC's) from meteor PROPERTY REQUIREMENTS FOR ELECTRONIC PACKAGING MATERIALS AND DESIGNS.ological satellite… more
Abstract:If you can't beat them, join them. Such is the philosophy of Space Exploration Associates, who hired the top talent in Russian and the new Republic of Georgia to develop advanced thermionic converters for SDIO. Unlike other highly publicized exchanged with the Russians, this work will be done in the… more
Abstract:A THERMIONIC FUEL ELEMENT (TFE) BASED ON ADVANCED URANIUM CARBIDE (UC) SOLID SOLUTION FUEL WITH RHENIUM EMITTER CLADDING SHOULD ALLOW MUCH BETTER PERFORMANCE THAN PRESENT DESIGNS. THE FUEL FORM WOULD BE A LONG, THIN, HOLLOW "VERMICELLI" SHAPE TO ALLOW VERY COMPACT REACTORS TO BE DESIGNED, DESPITE… more
Abstract:COMPOSITE MATERIALS ARE ATTRACTIVE FOR USE IN AIRCRAFT AND SPACECRAFT OWING TO PROPERTIES OF HIGH SPECIFIC STRENGTH. A PROBLEM CONFRONTING THE APPLICATION OF COMPOSITE MATERIALS FOR ROTORCRAFT IS THAT UNIMPROVED LANDING AREAS, AS WELL AS LOW ALTITUDE MISSIONS, RESULT IN SEVERE ABRASION OF THE… more
Abstract:A COLD CATHODE CAPABLE OF DELIVERING SEVERAL HUNDRED AMPS PER SQUARE CENTIMETER (UNDER AMBIENT CONDITIONS WITHOUT THE INTRODUCTION OF CESIUM VAPOR) WOULD BE VALUABLE FOR A NUMBER OF APPLICATIONS IN HIGH POWER HIGH FREQUENCY ELECTRONICS. ONE OF THE MOST HIGHLY SOUGHT APPLICATIONS IS THAT OF CATHODE… more
Abstract:Everybody knows that composites have high strength, low density, and great thermal properties. They would be great for a number of applications such as fins for spacecraft radiators. So why aren't they used more on spacecraft thermal systems? One reason is joining technology. Although many methods… more
Abstract:APPLIED TECHNOLOGY ASSOCIATES, INC., (ATA) DESIGNED, FABRICATED, AND PERFORMED AN INITIAL TEST OF A DEVICE WHICH REPRESENTS A NEW CONCEPT FOR AN INERTIAL, ANGULAR RATE SENSOR. THE SENSOR UTILIZES A MERCURY PROOF MASS WHOSE ANGULAR RATE IS DETERMINED FROM THE VOLTAGE GENERATED AS THE MERCURY MOVES… more
Abstract:THIS PROJECT ADDRESSES SYSTEMS TO REDUCE NOISE AND VIBRATIONS EMANATING FROM AUXILIAIY POWER UNITS (APUS) WHICH ARE BEING INITEGRATED INTO ARMY VEHICLES AND SHELTERS. EXCESSIVE NOISE AND VIBRATIONS ARE HARMFUL TO AND HINDER THE EFFECTIVENESS OF OPERATORS AND OCCUPANTS. IN MILITARY EQUIPMENT, IT IS… more
Abstract:THIS PROPOSAL IS TO USE OPTICAL FIBER GRADED-INDEX (GRIN) ROD LENSES TO DEVELOP A WEAPONS SIGHT THAT HAS MAGNIFICATION, A BRIGHT IMAGE, REQUIRES THE EYE TO ONLY FOCUS AT ONE DISTANCE, IS RUGGED, IS ACCURATE, IS SIMPLE, IS SMALL, IS USER FRIENDLY, AND IS COMPATABLE TO BE MOUNTED ON EXISTING WEAPONS.… 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.
