Aeroelastic Response and Protection of Space Shuttle External Tank Cable Trays

Multidisciplinary Design Optimization of the Space Shuttle External Tank

This study explored the multidisciplinary system design optimization of the External Fuel Tank of the SpaceTransportation-System. Initially, we used the return on investment as the single objective of the system. With the simplified external tank model, a series of simulation experiments were conducted to obtain the feasible starting design. We then performed the single objective optimization u...

Evaluation of Ice and Frost Accumulation on the Space Shuttle External Tank

Ice/frost formation on the Space Shuttle cryogenic propel 1 ant tanks presents a different problem from that of past launch vehicles. Lift off weight addition has been the primary concern on past launch vehicles. The primary ice/frost concern on the Shuttle vehicle is damage to the Orbiter Thermal Protection System due to ice/frost impact. The approach used to arrive at a solution to this uni­ ...

Jr.: Nonlinear Analysis of the Space Shuttle Superlightweight External Fuel Tank

Results of linear bifurcation and nonlinear analyses of the Space Shuttle superlightweight (SLWT) external liquid-oxygen (LO 2) tank for an important early booster ascent loading condition are presented. These results for thin-walled linear elastic shells that are subjected to combined mechanical and thermal loads illustrate an important type of response mode that may be encountered in the desi...

Efficient cable arrangement in cable stayed bridges based on sensitivity analysis of aeroelastic behaviour

Construction of cable supported bridges has experienced a great impulse in the past decade. Bridges having more than 800 m of span length were built in France and Japan and some bridges with span length of more than 1 km are going to be built, such as the Stonecuters bridge in Hong-Kong, and the Chongming in China (Fig. 1). Because of the increasing length of this class of bridges, they are bec...
