  • Analytic Free-Molecular Aerodynamics for Rapid Propagation of Resident Space Objects 

    Hart, Kenneth A.; Simonis, Kyle R.; Steinfeldt, Bradley A.; Braun, Robert D. (American Institute of Aeronautics and Astronautics, 2018-01)
    Aerodynamic forces and moments are significant perturbations on low-Earth-orbiting objects, second in magnitude to the nonspherical gravity field. Traditionally, the aerodynamic perturbations are calculated using a direct ...
  • CFD Study of an Over-Wing Nacelle Configuration 

    Berguin, Steven H.; Renganathan, Sudharshan Ashwin; Ahuja, Jai; Chen, Mengzhen; Perron, Christian; Tai, Jimmy; Mavris, Dimitri N. (Georgia Institute of Technology, 2018-10-05)
    Engine bypass ratio (BPR) has grown significantly over the years, due to a desire for increased efficiency, and the large fan diameters that have resulted are forcing the engines so close to the wing that there is no room ...
  • Georgia Tech Mars Exploration UAV Collaborative System: A Conceptual Design and Systems Engineering Study 

    Lacerda, Michel; Park, Dongjin; Beard, Robert; Schrage, Daniel (Georgia Institute of Technology, 2017-12-14)
    Exploration of Mars has been one of the focus of the aerospace community for its similarity with the Earth. The characteristics of Mars make possible an aerial flight even with the low pressure in its atmosphere. In an age ...
  • State Estimation using Gaussian Process Regression for Colored Noise Systems 

    Lee, Kyuman; Johnson, Eric N. (Georgia Institute of TechnologyIEEE, 2017-06)
    The goal of this study is to use Gaussian process (GP) regression models to estimate the state of colored noise systems. The derivation of a Kalman filter assumes that the process noise and measurement noise are uncorrelated ...
  • Parachute Dynamic Stability and the Effects of Apparent Inertia 

    Ginn, Jason M.; Clark, Ian G.; Braun, Robert D. (Georgia Institute of Technology, 2014-06)
    The dynamic stability and equilibrium conditions of a parachute are studied using a six degree of freedom dynamic model that includes apparent inertia effects. Existing parachute dynamic models are discussed and the selection ...
