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 ...

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 objective of this work is to determine the best possible polycrystalline zirconia from the standpoint of properties and cost for applications in storage heaters. Our prior work has shown that highly stable tetragonal t'-zirconia with domain structure containing (

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 ...

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 ...

High-power ammonia arcjet thrusters are being investigated as primary propulsion systems for carrying satellites into high altitude orbits. As a method to enhance the power levels and efficiency of the engine, the thermal emissivity of the outer anode surface must be substantially enhanced. Ideally, the anode material should be low density, both highly electrically and thermally conductive, and be ...

In the next generation of air-breathing high-performance engines, significant engine performance improvements are envisioned by combusting hydrogen with air in a regeneratively cooled carbon/carbon composite combustion chamber. Surfaces subjected to aerodynamic heating will also be cooled by recirculating hydrogen through cooling tubes. To date, approaches investigated have not had desired levels ...

ABSTRACT:For GPS denied navigation, there is a need for developing inertial measurement units (IMU), employing gyroscopes and accelerometers, with better accuracy and/or smaller volume and weight than the state of the art.Under Phase I, we have established the feasibility of realizing a superluminal ring laser gyroscope (SRLG) and a superluminal ring laser accelerometer (SRLA), based on diode-pump ...
