Scintillators have been used for over 90 years to detect ionizing radiation, but solid organic scintillator, commonly used in physics experimentation, suffer from errors caused by pulse pileup. To… more
Abstract:Two major objectives of the U.S. Army is to increase power density and reduce heat rejection. Reducing airflow requirements of the deisel engine will contribute toward both of these objectives. Reducing air-fuel ratio requirements is one of the major cost effective approaches available for… more
Abstract:The primary roadblock to the success of the high output Low Heat Rejection (LHR) diesel engine requiring little or no water cooling is the lack of effective liquid lubrication where target top ring reversal (TRR) temperatures between the cylinder liner and piston ring approach 1000 degrees F. … more
Abstract:Adhesive joining of materials has found widespread use in industry because of the simplicity and versatility of the process. However, adhesive applications in critical structural joints are still limited by the absence of reliable, rapid industrial NDE methods. Significant progress has been … more
Abstract:The topic presented in this proposal has direct application to the development and demonstration of high Mach combined cycle engines. The proposed effort would allow the coupling of a pulse detonation engine (PDE) with a realistic solid fueled gas generator. The specific key technical problems… more
Abstract:The opportunity addressed in this proposal is an innovative pulse detonation rocket engine (PDRE) which could significantly out-perform current state-of-the-art chemical rocket propulsion systems. The innovation is based in a novel combustion concept developed by Adroit Systems, Inc. (ASI) in the… more
Abstract:Adroit Systems Inc. (ASI) proposes to develop an innovative concept which reduces the required volume of predetonator mixture in pulse detonation engines (PDEs). The propulsive efficiency of the PDE hinges on the ability to quickly initiate a detonation in a fuel/air mixture. Since most… more
Abstract:The topic presented in this proposal has direct application to the development of non-lethal devices capable of temporarily incapacitating personnel, controlling crowds, immobilizing small vehicles, and other applications where a controlled amount of acoustic c energy needs to be delivered a a… more
Abstract:The opportunity addressed in this proposal is a fast-acting cryogenic injection valve for pulse detonation rocket engines (PDREs), which are predicted to significantly out-perform current state-of-the-art chemical deflagrative rocket propulsion systems. The developed valve would allow high mass… more
Abstract:Although technologies derived under the Integrated High Performance Turbine Engine Technology (IHPTET) initiative should result in higher performance of gas turbine engines, the durability of engine components continues to be one of the most important design issues which impacts their affordability… more
Abstract:A new class of thin film coating materials, diamond-like nanocomposites (DLN) have been developed. These materials have a combination of properties making them an excellent choice for use as wear resistant coatings on mechanical cryogenic coolers for space applications. In particular, the… more

Abstract:HIGH-DENSITY ENERGY STORAGE AND FAST DISCHARGE WILL BE CRITICAL IN A VARIETY OF HIGH POWER AEROSPACE APPLICATIONS. CAPACITORS ARE IDEAL FOR THESE PURPOSES, AS WELL AS FOR POWER CONDITIONING AND FILTERING. UNFORTUNATELY, BULK POWDER-BASED DIELECTRICS USED IN CAPACITORS HAVE SEVERE LIMITATIONS,… more
Abstract:DUE TO ITS UNIQUE PROPERTIES AND ITS ABILITY TO BE PROCESSED ANALOGOUSLY TO SILICON, SILICON CARBIDE (SIC) WILL BE AN IMPORTANT HIGH TEMPERATURE, HIGH POWER, AND HIGH FREQUENCY ELECTRONIC MATERIAL. THE BARRIER TO THIS DEVELOPING TECHNOLOGY WAS THE AVAILABILITY OF 6H-SIC SUBSTRATES. HOWEVER, THESE… more
Abstract:CHEMICAL VAPOR DEPOSITION (CVD) OF LEAD-BASED FERROELECTRICS SUCH AS LEAD TITANATE, LEAD ZIRCONATE TITANATE (PZT), AND LEAD LANTHANUM ZIRCONATE TITANATE (PLZT), IS THE MOST PROMISING MANUFACTURING METHOD FOR A WIDE VARIETY OF NEXT GENERATION ELECTRONIC DEVICES INCLUDING RADIATION-HARD NON-VOLATILE… more
Abstract:Aircraft landing gear, and wheels in particular, are subjected to heavy loads during service. Controlled surface compressive stresses help to improve the fatigue life by reducing the probability of crack initiation and propagation from the wheel surface. Manufacturers such as Allied Signal… 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.
