ABSTRACT: This proposal is concerned with the development of a novel failure initiation and progressive failure analysis modeling method for advanced composite structures, including the analysis of selected structural joints utilizing a statistically based micromechanics model embedded in a 3D non-linear finite element code. The method accounts for the interaction between out-of-plane failure and ...

The objective of this program is to build upon many decades of experience with magnetic flowmeters to develop a next-generation system to measure the burning surface admittance of high-energy-density solid propellants at high frequencies and pressures. Using the results of research on solid propellant rocket motor combustion instability from the past fifty years, one can directly measure the ac ...

The proposed research program focuses on design, fabrication, and characterization of quantum-dot infrared photodetectors (QDIPs) which features bias-tunable parameters, including the spectral response, optical gain, and operating time. Wide variations of detector parameters can be realized through the bias-tunable potential barriers surrounding quantum dots. Changes in bias will transform the ba ...

Impact Technologies, in collaboration with the Georgia Institute of Technology, the Rochester Institute of Technology and the Boeing Company, is proposing to complete the development, testing and evaluation of a novel biologically-inspired Micro Air Vehicle (MAV) conceptualized in Phase I and capable of agile and high endurance flight operations in dense and cluttered urban environments. Phase I a ...

In this Small Business Technology Transfer Program (STTR) - Phase II project we will build photonic integrated circuits that perform flip-flop and optical switching operations on silicon platform. These circuits are based on our Phase I work where we have established the feasibility of using coupled microdisk resonators and active waveguides coupled to a single microring resonator to realize bista ...

Michigan Aerospace Corporation proposes to develop an optical MEMS based skin friction sensor specifically designed for hypersonic applications. This instrument will be capable of shear stress resolutions as small as 0.01 Pa, have a high dynamic range, and data rates in excess of 100 Hz. The sensor will be compact and tolerant of the extreme environmental conditions of hypersonic propulsion test f ...

The realization of materials with record mechanical and electrical properties is of paramount importance to the Air Force and other branches of the US Armed Forces. Layer-by-layer (LBL) assembly is capable of producing nanocomposite materials with record properties surpassing those made by many traditional composite preparation techniques. However the process is time consuming and typically yiel ...

A computational and experimental research program is proposed to develop and validate a high-fidelity 3D non-equilibrium magnetohydrodynamic (MHD) plasma compressible flow code for advanced aerospace applications. The code will incorporate a physics-based kinetic model of air plasma with non-equilibrium conductivity sustained by an externally applied electric field. The model will include electron ...

This STTR will provide a prototype Electronics Package that integrates disparate streams of spectrographic and topographic data to provide high resolution imaging and chemical specificity at the nanoscale. It will enable development of a commercial instrument delivering routine near-field tip-enhanced optical imaging with spatial resolutions in the range of 10-50nm along with topographic (Atomic F ...

High energy density and high power capacitors operating at a high frequency are in great demand for a variety of residential, military, medical, and industrial applications. In fact, a large percentage of the cost of alternative energy components is consumed by the cost of capacitors. Although there have been some developments in the fabrication of inorganic super-capacitors, the problems encoun ...
