Comparison of Return to Launch Site Options for a Reusable Booster Stage
(Georgia Institute of Technology, 2005-11-10)
There is a major need in the U.S. Air Force to develop launch vehicles that can be
used for Operational Responsive Spacelift and possibly be used for rapid global
Strike. One strategy to achieve these mission goals is ...
Tempest: Crew Exploration Vehicle Concept
(Georgia Institute of Technology, 2005-07)
Tempest is a reusable crew exploration vehicle (CEV) for transferring crew from the
Earth to the lunar surface and back. Tempest serves as a crew transfer module that supports
a 4-person crew for a mission duration of ...
Power Based Sizing Method for Aircraft Consuming Unconventional Energy
(Georgia Institute of Technology, 2005-01-10)
Traditionally, most fixed wing and rotary wing aircraft have been powered by internal
combustion engines that consume hydrocarbon fuels. Only in a few exceptional designs, such
as solar powered air-vehicles, are attempts ...
Limited authority adaptive flight control
(Georgia Institute of Technology, 2000-12)
Mars-back Approach to Moon-Mars Exploration System Commonality
(Georgia Institute of Technology, 2005-11-09)
The Mars-back approach entails the development of a common system for the exploration
of Moon and Mars by first looking at the requirements placed upon the system by the
Mars exploration case and then projecting the ...
Impact and penetration studies: simplified models and materials design from ab initio methods
(Georgia Institute of Technology, 2006-01-13)
In recent impact and penetration mechanical tests, steel projectiles (AISI4340) were impacted into targets like concrete with striking velocities (1200 m/s to 1500 m/s). Results indicated a material removal from the nose ...
Design of a Long Endurance Titan VTOL Vehicle
(Georgia Institute of Technology, 2006-03)
Saturn's moon Titan promises insight into many key scientific questions, many of which can be investigated only by in situ exploration of the surface and atmosphere of the moon. This research presents a vertical takeoff ...
Efficient and Robust Approaches to the Stability Analysis and Optimal Control of Large-Scale Multibody Systems
(Georgia Institute of Technology, 2007-06-14)
Linearized stability analysis methodologies, system identification algorithms and optimal control approaches that are applicable to large scale, flexible multibody dynamic systems are presented in this thesis.
For ...
Reusable Exploration Vehicle (REV): Orbital Space Tourism Concept
(Georgia Institute of Technology, 2005-05)
On the heels of the recent success of the X-Prize, sub-orbital space tourism is nearly a
reality. Though the requirements are significantly tougher, orbital space tourism is the next
logical step. The Reusable Exploration ...
Aztec: A TSTO Hypersonic Vehicle Concept Utilizing TBCC and HEDM Propulsion Technologies
(Georgia Institute of Technology, 2004-07)
The Aztec reusable launch vehicle (RLV) concept is a two-stage-to-orbit (TSTO) horizontal takeoff, horizontal landing (HTHL) vehicle. The first stage is powered by ten JP- 5 fueled turbine-based combined-cycle (TBCC) ...
