Space Shuttle Orbiter Structures and Mechanisms

The Space Shuttle Orbiter has performed exceptionally well over its 30 years of flight experience. Among the many factors behind this success were robust, yet carefully monitored, structural and mechanical systems. From highlighting key aspects of the design to illustrating lessons learned from the operation of this complex system, this paper will attempt to educate the reader on why some subsystems operated flawlessly and why specific vulnerabilities were exposed in others. Specific areas to be covered will be the following: high level configuration overview, primary and secondary structure, mechanical systems ranging from landing gear to the docking system, and windows.

X-38 Seal Development

This viewgraph presentation provides information on the development of seals for the X-38 spacecraft. This seals will be an important part of the X-38's thermal protection system (TPS) in its service as a crew return vehicle (CRV) associated with the International Space Station (ISS).
