    Development of Trajectory Simulation Capabilities for the Planetary Entry Systems Synthesis Tool
    (Georgia Institute of Technology, 2005-12-17) Kipp, Devin Matthew
    A Simulated Trajectory Analysis code for Planetary Entry (STAPLE) has been developed as a contributing disciplinary analysis tool within the framework of a larger entry systems synthesis tool. STAPLE performs 3-degree of freedom trajectory analysis for atmospheric flight at arbitrary planetary bodies. The tool is applicable to both ballistic and lifting entry trajectory simulations and includes a modest guidance capability that enables aerocapture and controlled entry simulations. Event modeling capabilities include staging, parachute inflation, parachute release, and propulsive descent based on a gravity turn guidance law. Performance has been validated against existing analysis codes, Mars Pathfinder flight experience, and Aeroassist Flight Experiment studies.

    Probabilistic Assessment of the Space Tourism Industry What Will it Take to Make it Profitable?
    (Georgia Institute of Technology, 2005-05-01) Young, James J.
    Forty four years ago Yuri Gagarin became the first person to travel into space; this sparked a heated “space race” between the United States and the Soviet Union which ended with the historic moon landing in 1969. This began the world wide love for space travel and sparked interest in a possible future space tourism industry. It has taken nearly 35 years, but the space tourism industry has finally matured. With the successfully launch of SpaceShipOne, which captured the X-Prize in October of 2004, a vehicle is now finally available that can provide affordable access to space. Virgin Galactic has bought the rights to this design and will begin offering sub-orbital space flights in 2007 for a ticket price of around $200,000. The goal of this study will be to determine the economic viability of the future space tourism industry. The study will include an economic evaluation of the currently proposed SpaceShipTwo Virgin Galactic partnership that will begin providing sub-orbital space flights in 2007. A second study will then be preformed to characterize a vehicle configuration and economic business model that will be most profitable in this space tourism industry. These models will be analyzed using LMNoP, an economic business case analyzer developed in the Space Systems Design Lab to predict the economic viability of a space tourism business model. Probabilistic analysis will be used to help provide greater confidence in the results then could be achieved through a deterministic result. It is the hope that the result of this study will help to establish a baseline economic model for a successful space tourism industry and will provide proof that this industry is within reach.

    Comparison of Transition to Flight Methods for a Titan Helicopter
    (Georgia Institute of Technology, 2005-04-29) Prakash, Ravi
    Two methods of transition to flight for a Titan helicopter were compared: a lander option and a mid-atmospheric deployment. The methods were compared based on the ability of each to allow the helicopter to successfully commence flight as well as satisfy the mass and volume constraints of the aeroshell. Landing the helicopter before its initial flight proved too massive for the baseline mission, but an acceptable solution was found with a smaller helicopter that could achieve a heavily compromised mission. A mid atmospheric deployment satisfied all the criteria while allowing enough mass for the helicopter to achieve its baseline mission. Although it was the higher risk option, the ability of the mid-atmospheric deployment to achieve the baseline mission was the defining factor in its choice as the transition to flight method for the Titan helicopter.
