摘要

As gossamer structures are planned for possible deployment on various missions over the next decade, the development of verified computational models to predict their dynamic behavior on orbit is vital. This is because extensive testing of full-scale gossamer prototypes under operational conditions (e.g., 0 g, vacuum) is not possible on Earth due to their large size, and so computational models will be the primary means of exploring various design alternatives. To verify the accuracy of these computational models, subscale, full-field surface data from dynamic measurements of gossamer structures performed under various conditions (atmospheric and gravitational) will be used to verify subscale computational models, which can then be scaled up to predict full-scale structure performance. To increase the robustness of the subscale computational models, data for model verification need to be obtained under a variety of operating conditions. Whereas atmospheric loading of gossamer subscale models is typically varied by performing experiments in a vacuum chamber at various pressures, few (if any) experiments that specifically vary gravity field magnitude have been documented. The work presented here is a follow-up experiment to that performed by Meyer et al.
