We propose to develop a general purpose computer code for calculating the scattering from antennas on an aircraft, which is described by a CAD file. The scattering contribution will include both the passive structure mode and active irradiation mode, calculcated by a hybrid of a high-frequency ray technique and a rigorous finite element technique. The proposed code will be made compatible with the ...

WEAPONS DELIVERY SYSTEMS FOR ARMAMENTS REQUIRE MODERNIZATION TO REFLECT THE "SMART SKINS" PACKAGING CONCEPT WHICH IS UNDER DEVELOPMENT FOR AIRCRAFT. ARMAMENTS ARE GENERALLY SMALLER AND RADAR SENSORS AND SEEKERS WILL OPERATE AT SHORTER WAVELENGTHS, OFTEN IN MILLIMETER WAVELENGTHS. THE DEVELOPMENT OF A UNIFIED ANTENNA/TRANSCEIVER FOLLOWING "SMART SKINS" TECHNOLOGY REQUIRES AN ELECTRONICALLY SCANNED ...

RESEARCH WILL BE CONDUCTED BY HICHEM CORPORATION, TO DEVELOP A NEW TECHNOLOGY FOR PYROLYSIS OF SCRAP TIRES. DISPOSAL OF USED TIRES IS A BIG PROBLEM IN THE WORLD, ESPECIALLY USA, SINCE MORE THAN 2.5 MILLION TIRES ARE DISCARDED EACH YEAR. MOST OF THESE TIRES ARE DISPOSED IN LANDFILLS. PYROLYSIS OF SCRAP TIRES HELPS TO RECOVER AND REUSE MOST OF THE VALUABLE CHEMICAL AVAILABLE IN TIRES. PYROLYSIS OF S ...

The ability to display critical information within the optical train of a night vision device has become a requirement in the aviation community. The current display approaches rely on CRT's, optical combiners, lenses, and fiber optic cable to inject the symbology within the optical train of the night vision device. Besides decreased image tube life, bulkiness, and additional weight, the performan ...

THIS RESEARCH IS INTENDED TO DETERMINE THE FEASIBILITY OF FABRICATING HIGH ENERGY DENSITY CAPACITORS BY MEANS OF AN IONIC POLYMER MEMBRANE AS ELECTROLYTE MATERIAL AND AN ELECTRONICALLY CONDUCTING POLYMER AS ELECTRODE. THE NECESSARY HIGH DEGREE OF SURFACE AREA CONTACT BETWEEN ELECTRODE AND ELECTROLYTE WILL BE EFFECTED BY INTERMIXING THE CONTACING SURFACES TO PROVIDE AN INTERPENETRATING POLYMER NETW ...

Cubane C8H8 is potentially an extremely valuable fuel substitute for the kerosene-based rocket propellant RP-1. The classical Eaton synthesis to yield cubane 1,4-dicarboxylic acid in five steps involves a key photochemical reaction. The steps before and after the critical 2+2 cycloaddition are standardized and readily scalable. However, this steps alone prevents scale-up. We will develop a non-pho ...

ABSTRACT: Quantum key distribution (QKD) is an exciting application of quantum theory to the important real-world problem of secure communication. Specifically, QKD may allow for provably secure key distribution. These random keys can then be used either in a one-time pad style encryption system (for absolute security at low rates) or a standard encryption system (for high security at high rates) ...

ABSTRACT: MicroLink will develop a high-efficiency, flexible photovoltaic blanket, which will reduce solider borne weight by reducing battery requirements. The photovoltaic blanket will combine ultra-thin, flexible high-efficiency, GaAs-based multi-junction solar cells, made using MicroLink"s proprietary epitaxial lift-off (ELO) process, with a novel packaging approach that involves laminating a ...

ABSTRACT: Sapphire possesses a number of physical properties, including high strength, high melting point, chemical inertness, and excellent transparency in the visible and IR spectrum, which make it an attractive window material for military applications. For Phase I, Rubicon Technology demonstrated a sapphire crystal growth process to MRL 5 capable of growing slabs 20"x 14". During Phase II th ...

ABSTRACT: An engineering computational simulation tool based on the shrinking core model of nanoparticle combustion is proposed to investigate ignition, combustion and performance of nano-energetic particles in a variety of oxidizing environments, including those found in rockets and air breathing propulsion devices. The computational model will include appropriate models for the bulk, oxide, and ...
