ABSTRACT: Busek Co. Inc. and Massachusetts Institute of Technology (MIT) propose to explore the physical limits of ionic liquid propulsion via development of new theory to explain effects of close packing emission density and to predict performance limits. The research is motivated by observations and tests demonstrating that emission from 2-dimensional porous surfaces yields order of magnitude g ...

ABSTRACT: The Tai-Yang Research Company (TYRC) of Tallahassee, FL in collaboration with Dr. Justin Schwartz of the North Carolina State University (NCSU) in Raleigh, NC propose in this Phase 2 effort to develop the critical technologies necessary for the implementation and operation of an airborne high temperature superconductor (HTS) superconducting magnetic energy storage (SMES) device with par ...

ABSTRACT: Due to increasing communications demand for tactical mission operations force the DoD to initiative to migrate the existing circuit-switched, bent-pipe satellite communication systems to the onboard packet switched satellite systems using Internet Protocols. The new approach offers significant flexibility and performance gain, but there are still tough challenges, e.g., high bit error r ...

ABSTRACT: Given the results obtained in the Phase I effort, we are now in a position to advance to the next generation of High Power Phased Array Transceiver Systems. The new approach proposed here is to use enough elements in the phased array to ensure that significant wavefront compensation performance can be obtained with only piston commands. A system of this nature can be developed in two ...

ABSTRACT: LongShortWay Inc, Boston University, and Applied Communication Sciences propose to develop a dynamic multi-sensor learning system that can adaptively detect target types and activities and schedule sensors to optimize the detection rate BENEFIT: Improved detection rate, increase field of view

ABSTRACT: aBeam Technologies, Inc. proposes a new printing technology for fabricating photonic devices. This nanofabrication process could potentially reduce to a single step, the fabrication of photonic crystals by direct imprinting on inorganic materials. The method is low cost and suitable for large-scale areas. In Phase I, the demonstration of feasibility of the method provides the basis for ...

ABSTRACT: We propose development of an efficient physics-based computational capability for simulation of complex MIMO radar clutter, with applicability to single- and multi-platform transmit-receive systems, which accounts accurately, on the basis of Maxwell's equations, for all relevant multi-path propagation and scattering effects. Our effort will enable simulation of scattering by realis ...

ABSTRACT: NextGen Aeronautics, leveraging past experience in generating stress spectra from static and vibratory loads as well as knowledge of gas turbines, is proposing a method for estimating blade stresses from multiple vibratory loads in rotating systems from limited manufacturer data from Campbell diagrams and strain gage blade stresses. The method hinges on utilizing 3D parametric generic i ...

ABSTRACT: Strong coupling in ionized plasmas occurs when inter-particle interactions result in correlation energies that are comparable to the mean kinetic energy of the thermal motion of individual particles. Strongly coupled plasmas are known to be present in a number of physical systems including ultra-cold plasmas created in the laboratory and present in the ionosphere, explosive gases associ ...

ABSTRACT: The U.S. Air Force has a need to develop a new class of advanced, wide field of view (WFOV) imaging sensors that sample the radiation field in multiple modes: spectral, temporal, polarization, and detailed object shape. These multimodal sensors are to be deployed on high altitude drones to enhance their intelligence, surveillance, and reconnaissance (ISR) capabilities. Smaller versions o ...
