回転二重波折りソーラーセイル膜面のスピン展開特性(S65-2 宇宙用膜構造,S65 宇宙構造物)

A concept of rotationally skew fold is proposed for the spinning solar sail to meet with the structural properties. The structural properties of the rotationally skew fold membrane are examined from the view point of packaging properties, deployment characteristics, and flatness of the deploying membrane with experiment models. The results indicated that the rotationally skew fold membrane has advantageous for stable deployment with easy packaging, although slightly higher rotational rates are required for the full deployment. The similarity non-dimensional parameter was also derived with the large deformation theorem of a spinning plate.
