- W2067874257 abstract "The initial structural design of the Space Shuttle Main Engine was capable of withstanding all known shock and vibratory loads to be encountered during its useful life. However, during the development stage, some unexpected dynamic loads were uncovered that required redesign. The successful incorporation of the knowledge of shock and vibration loads gained during the development of these engines led directly to the first successful flight, and will ensure future successful flights of the Space Shuttles. This paper is a review of the development of the SSME zonal vibration criteria, laboratory vibration tests using zonal criteria to verify life of engine components, and the resolution of unexpected structural problems in turbine blades and in the main injector LOX post due to hot gas flow. Hardware modifications were made to resist the dynamic loads associated with the vibration environments and the hot gas flow until long lead time redesigns could be incorporated. This experience and knowledge will be useful to the design of future liquid rocket engines." @default.
