Centrifugal deployments have a possibility of unfolding large membranes without using extendable masts. Understanding and predicting the deployment dynamics are important to realize large membrane space structures. In this paper, deployment experiments of hexagonal membranes with coarse and fine spiral folding patterns are conducted in vacuum under gravity. Numerical simulations of the centrifugal deployments are also performed employing spring-mass system which models in-plane stiffness of thin membranes and enables fast numerical analysis. Modelings of buckling, creases, air drag and damping are added to the spring-mass system model and initial shapes are adjusted to experimental models. The experimental and numerical results are compared to examine the characteristics of the deployment dynamics and the validity of the numerical., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064734065},
