  • The Wind and Beyond
    James R. Hansen / National Aeronautics and Space Administr
    How ideas about aerodynamics first developed and how the science and technology evolved to forge the airplane into the revolutionary machine that it became is the epic story told in this projected six-volume series.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it. This work was reproduced from...

  • The Numerical Analysis of a Turbulent Compressible Jet
    James R. Debonis / National Aeronautics and Space Administr
    A numerical method to simulate high Reynolds number jet flows was formulated and applied to gain a better understanding of the flow physics. Large-eddy simulation was chosen as the most promising approach to model the turbulent structures due to its compromise between accuracy and computational expense. The filtered Navier-Stokes equations were developed including a total energ...

  • The Effect of Wake Passing on Turbine Blade Film Cooling
    James David Heidmann / National Aeronautics and Space Administr
    The effect of upstream blade row wake passing on the showerhead film cooling performance of a downstream turbine blade has been investigated through a combination of experimental and computational studies. The experiments were performed in a steady-flow annular turbine cascade facility equipped with an upstream rotating row of cylindrical rods to produce a periodic wake field s...

  • Analyzing Discrepancies in a Software Development Project Change Request (CR) Assessment Process and Recommendations for Process Improvements
    Kenneth James Cunningham / National Aeronautics and Space Administr
    The Change Request (CR) assessment process is essential in the display development cycle. The assessment process is performed to ensure that the changes stated in the description of the CR match the changes in the actual display requirements. If a discrepancy is found between the CR and the requirements, the CR must be returned to the originator for corrections. Data was gather...

  • High Temperature Superconductivity in Praseodymium Doped (0%, 2%, 4%) in Melt-Textured Y(1-x)Pr(x)Ba2Cu3O(7-delta) Systems
    Claudell James / National Aeronautics and Space Administr
    A study of the magnetic and structural properties of the alloy Y(1-x)Pr(x)Ba2Cu3O(7-delta) of 0%, 2%, and 4% doping of praseodymium is presented. The resulting oxides of the alloy series are a high-temperature superconductor Y-Ba-Cu-O, which has an orthorhombic superconducting crystal-lattice. Magnetic relaxation studies have been performed on the Y-Pr-Ba-CuO bulk samples for f...

  • Three-Dimensional Visualization of Ozone Process Data
    James E. Rickman / National Aeronautics and Space Administr
    In the last ten years, significant developments have occurred in the separate fields of three-dimensional visualization and air quality. The primary goal of this research is to find means and methods of coupling air quality data to three-dimensional visualization in order to enhance ozone process analysis. Process analysis data refers to the individual rates associated with the...

  • Experimental Results and Issues on Equalization for Nonlinear Memory Channel
    James LeBlanc / Lu Yuan / National Aeronautics and Space Administr
    This thesis investigates the effects of the High Power Amplifier (HPA) and the filters over a satellite or telemetry channel. The Volterra series expression is presented for the nonlinear channel with memory, and the algorithm is based on the finite-state machine model. A RAM-based algorithm operating on the receiver side, Pre-cursor Enhanced RAM-FSE Canceler (PERC) is develope...
