TY  - JOUR
AB  - A novel rigid deployable aeroshell architecture has been developed, where rigid panels with a thermal protectionsystem layer are connected between retractable ribs. Following origami principles, an optimal fold pattern is selectedand imposed on the panels to ensure efficient flat stowage during launch and repeatable deployment. The designprocess includes minimizing the number of folds to reduce stacking height and maximizing the angles between eachfold line to avoid an unfavorable aerothermodynamic response. The dynamic behavior of the optimal design isanalyzed with the aid of a dynamic multibody analysis model. Results from the dynamic model show that the processof deployment is highly sensitive to panel geometry (especially panel thickness and hinge design). Robust, repeatable,and controllable deployment is most readily achieved with a small (but nonzero) panel thickness and selection ofinterpanel hinges, which allow a degree of over-rotation, avoiding a premature hard stop, which would otherwiseprevent full deployment. Modeled results have been verified through experimental testing of a 0.4-m-diam scalemodel.
