ARI is developing an aircraft exhaust sampling system that transitions condensable species to the condensed phase in a manner that mimics what happens when the exhaust is emitted into the atmosphere. Standard engine-exit plane measurements are not suitable for these volatile particles because they form downstream of the aircraft as the exhaust plume mixes with ambient air and cools. Downstream mea ...

THE PROPOSED WORK INVOLVES APPLICATION OF SUPPORTED MOLTEN SALT CATALYSIS TO THE CATALYTIC ENDOTHERMIC DEHYDROGENATION OF HIGH ENERGY-DENSITY AVIATION FUELS. THE CATALYSTS OF INTEREST ARE HETEROGENEOUSLY DISPERSED PLATINUM AND NICKEL, TO BE USED ALONE OR IN BIMETALLIC CLUSTERS. THE MOLTEN SALTS TO BE USED INCLUDE BINARY AND TERNARY EUTECTICS INVOLVING ALKALI METAL CHLORIDES AND HYDROXIDES. THE SUP ...

R3Logic, Inc., in collaboration with Tezzaron Semiconductor will develop a rad-hard multi-core embedded processor / memory system that will be fabricated in a multi-layer 3-D integrated circuit. Phase I will focus on the system design. We will complete the RTL to GDSII synthesis of the processor and system components. The stack will incorporate Tezzaron’s patented 3-D Octopus memory, which has b ...

Increasing the power density of current jet aircraft engines requires the replacement of conventional high temperature materials by new materials capable of operating at higher temperatures. Ceramics and ceramic matrix composites (CMCs) represent excellent candidates for increased use in hot engine parts due to their ability to withstand temperatures in excess of 2000 C. Due to the complexity of t ...

APPLICATION OF ADVANCED ORGANIC COMPOSITE AT CRYOGENIC TEMPERATURE IS OF CURRENT INTEREST. HOWEVER, RELATIVELY LIMITED DEVELOPMENT WORK HAS BEEN DONE IN THIS AREA. OUR UNDERSTANDING OF THE MECHANICAL AND CHEMICAL BEHAVIOR OF AN ORGANIC COMPOSITE MATERIAL AT CRYOGENIC ENVIRONMENT IS SOMEWHAT LACKING. IN ORDER TO UNDERSTAND THE FUNDAMENTAL MECHANISMS THAT AFFECT THE PERFORMANCE OF AN ORGANIC COMPOSI ...

WE PROPOSE THE DEVELOPMENT OF GLOBAL SPECTRAL NUMERICAL WEATHER PREDICTION (NWP) MODELS SPECIALLY DESIGNED TO TAKE ADVANTAGE OF MULTIPROCESSING COMPUTERS. SEVERAL CANDIDATE ALGORITHMS WILL BE DESIGNED AND ANALYZED. THE BEST DESIGNS WILL BE CODED AND TESTED IN A SIMULATED MULTIPROCESSOR. THIS STUDY IS IMPORTANT BECAUSE OPERATIONAL NWP IS TIME CONSTRAINED AND LIMITED BY AVAILABLE COMPUTING POWER. FU ...

SOLID BORON HAS LONG BEEN RECOGNIZED AS A POTENTIAL HIGH VOLUMETRIC DENSITY PROPELLANT FOR VOLUME LIMITED ROCKET AND AIR BREATHING PROPULSION SYSTEMS. HOWEVER, ACHIEVING THIS POTENTIAL HAS BEEN DIFFICULT DUE TO LOW COMBUSTION AND HEAT RELEASE EFFICIENCIES IN CONVENTIONALLY DESIGNED COMBUSTORS. A THREE PHASE MODEL OF BORON ASSISTED COMBUSTION IS POSTULATED AND THE ROLE THAT KINETIC SENSITIVITY ANAL ...

SPACE-BASED FACILITIES FACE AN UNEXPECTEDLY HOSTILE ENVIRONMENT AT ORBITAL ALTITUDES DUE TO CHEMICAL INTERACTIONS WITH ATOMIC OXYGEN AT THE HIGH VELOCITIES OF ORBITING SPACECRAFT. DEGRADATION AND EROSION OF MATERIALS FACING INTO THE ATMOSPHERIC WIND POSE A THREAT TO THE EFFECTIVE LIFE AND UTILITY OF SATELLITES, SPACE STATION SYSTEMS, AND EXPECIALLY SPACE-BASED OPTICAL INSTRUMENTATION. WE PROPOSE T ...
