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 ...
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 ...
3rd International Planetary Probe Workshop
(Georgia Institute of Technology, 2005-06-15)
Planetary entry system synthesis tool, a method for hypersonic aerodynamic shape optimization
(Georgia Institute of Technology, 2008-03-31)
The Mars Airplane: A Credible Science Platform
(Georgia Institute of Technology, 2004-03)
Significant technology advances have enabled planetary aircraft to be considered as viable science platforms. Such systems fill a unique planetary science measurement gap, that of regional-scale, near-surface observation, ...
Entry System Options for Human Return from the Moon and Mars
(Georgia Institute of Technology, 2005-08)
Earth entry system options for human return missions from the Moon and Mars were analyzed and compared to identify trends among the configurations and trajectory options and to facilitate informed decision making at the ...
Challenges of Mars Entry, Descent and Landing
(Georgia Institute of Technology, 2006-03)
The United States has successfully landed five robotic systems on the surface of Mars. These systems all had landed mass below 0.6 metric tons (t), had landed footprints on the order of hundreds of km and landed at ...
Daedalon: A Revolutionary Morphing Spacecraft Design for Planetary Exploration
(Georgia Institute of Technology, 2005-01)
The product of a study sponsored by the NASA Institute for Advanced Concepts (NIAC), Daedalon is a spacecraft design baselined for Mars which utilizes morphing wing technology to achieve the design objective of a standard, ...
Modeling Approach for Analysis and Optimization of a Long-Duration Mars Airplane
(Georgia Institute of Technology, 2004-05)
The goal of this study was to determine the best system level modeling tool for the design of a long endurance Mars airplane mission, and to use this tool to determine the best configuration for the aircraft. The mission ...
Cadmus: A Europa Lander Mission Concept
(Georgia Institute of Technology, 2005-03)
The Cadmus mission responds to the need for a Europa surface exploration mission in the 2021 time frame that complements and extends the science performed by the Jupiter Icy Moons Orbiter (JIMO) and Galileo spacecraft. ...
