Development and Testing of a 3-D-Printed Cold Gas Thruster for an Interplanetary CubeSat
(Georgia Institute of Technology, 2018-03)This paper describes the development and testing of a cold gas attitude control thruster produced for the BioSentinel spacecraft, a CubeSat that will operate beyond Earth orbit. The thruster will reduce the spacecraft ... -
Towards Optimal Human-Machine Teaming
(Georgia Institute of Technology, 2019-07-29)Machines were initially designed to take over manual tasks. Over time, as sensors and algorithms became more capable, decision-making has been automated via prescribed rules. Further, when these rules can be verified a ... -
Sky Walking: An Astronaut's Journey
(Georgia Institute of Technology, 2020-01-16)Four-time space traveler Tom Jones shares the personal and spiritual experience of space exploration. You’ll rocket through a rumbling blast-off, soar into orbit, spacewalk at the Space Station, endure a fiery reentry, and ... -
A full scale atmospheric flight experimental research environment for Titan exploration devices
(Georgia Institute of Technology, 2019-12)We propose to develop a full-accuracy flight test environment for Titan, the largest moon of Saturn. The experiment would use reduced-g atmospheric flights with a standard aircraft, with appropriate equipment, including a ... -
A full scale atmospheric flight experimental research environment for the Mars helicopter
(Georgia Institute of Technology, 2019-09-09)This paper proposes to test a full-accuracy ight test experiment for the Mars helicopter through an atmospheric reduced-g flight housing a vacuum chamber. -
Orion Capsule Launch Abort System Analysis
(Georgia Institute of Technology, 2016)The objective of this report is to provide an analysis the Orion spacecraft’s Launch Abort System (LAS). A launch abort system aims to remove the crew away from a failing launch vehicle as soon as possible during the ... -
Analytic Free-Molecular Aerodynamics for Rapid Propagation of Resident Space Objects
(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
(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
(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
(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
(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 ... -
A Comparison of Automatic Nap-of-the-Earth Guidance Strategies for Helicopters
