Structural Design - NASA

The Space Shuttle a mostly reusable, human-rated launch vehicle,spacecraft, space habitat, laboratory, re-entry vehicle, andaircraft was an unprecedented Structural engineering challenge. The Design had to meet several demands, which resulted in innovativesolutions. The vehicle needed to be highly reliable for environmentsthat could not be simulated on Earth or fully modeled analytically for combined mechanical and thermal loads. It had to accommodatepayloads that were not defined or characterized. It needed to be weightefficient by employing a greater use of advanced composite materials,and it had to rely on fracture mechanics for Design with acceptable life requirements. It also had to be certified to meet strength and liferequirements by innovative methods. During the Space ShuttleProgram, many such Structural Design innovations were developed and extended to vehicle processing from flight to InnovationsStructural Design Introduction Gail ChaplineOrbiter Structural Design Thomas MoserGlenn MillerShuttle Wing Loads Testing and Modification Led to Greater CapacityTom ModlinInnovative Concept for Jackscrews Prevented Catastrophic FailuresJohn FraleyRichard RingCharles StevensonIvan VelezOrbiter Structure QualificationThomas MoserGlenn MillerSpace Shuttle Pogo NASA Eliminates Bad Vibrations Tom ModlinPressure Vessel ExperienceScott ForthGlenn EcordWillard CastnerNozzle Flexible Bearing

structural design included the evolution of design loads. The Orbiter structure was designed to an early set of loads and conditions and certified to a later set. The shuttle achieved first-flight readiness through a series of localized structural modifications and operational flight constraints. During the early design phase, computer analyses ...
