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: The Air Force seeks to improve the accuracy of orbit specification and of 72-h orbit predictions beyond present capabilities. Thermospheric neutral density and satellite ballistic coefficient strongly impact satellite drag estimation, which is a leading source of error in orbit predictions in LEO. The goal of this Phase II project is to develop a satellite drag specification capability ...

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: 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: 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: 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: Space solar power systems range in size from the International Space Station with 8 solar arrays producing 84,000 watts all the way down to body-mounted single wafers on individual cubesats. The current state-of-the-art relies on multi-junction gallium arsenide or inverted metamorphic cells affixed to rigid structural panels. The need for a low-mass, high energy output solar array for ...

ABSTRACT: Solar arrays play a key role in the operation of spacecrafts and unmanned aerial vehicles. Traditionally, inorganic semiconductor based solar arrays have been used for space applications because of their highest efficiencies. However, these solar arrays have several major limitations like extremely high cost, low specific power and large stowage volume. Organic photovoltaic (OPV) module ...

ABSTRACT: This Phase I effort will involve the development of an ultra low cost, high specific power, modular and flexible solar array module using currently available thin-film solar cells, innovative interconnects, and flexible encapsulation. The high efficiency thin-film solar cells will enable high specific power and flexibility in the module. The interconnect scheme and encapsulation will a ...

ABSTRACT: Frontier Technology, Inc. (FTI) and its research partners, University of Florida (UF) and Lockheed Corporation, propose to enhance fusion of multimodal (EO, IR, acoustic, radar, etc.) multisensor datastreams. Phase I will: (1) Determine physics models for apparent properties of targets and inherent properties of sensors; (2) Integrate target and sensor physics models to produce Multi ...
