 note = {第一報[1]に続きヨーヨー・デスピンの運動解析と実験が行なわれた。運動解析は三次元モデルにおける硬式ヨーヨーに関して行なわれ,phase1およびphase2でのデスピナーの運動を明らかにする理論式が導かれた。次にばね式ヨーヨーを二次元モデルで作動させる実験が行なわれ,理論との一致が確認された。また断面がハ角形をした模擬衛星を用いて,ケーブルを巻き付ける面が円でない場合の実験が行なわれ,これがデスピナーの運動に与える影響は小さいことが検証された。以上の結果から,このデスピン方式が実際の衛星に十分適用し得るという見通しが得られた。, The three-dimensional problem of despinning a rotating rigid body by the rigid yo-yo despin device is considered. Although studies have been made previously [1], [2] for PHASE 1 (in which the wire is changing in length and is tangent to the satellite), there has been little effort to analyze the three-dimensional motion of the yo-yo in PHASE 2 (in which the length of wire is constant but its position is changing from tangent to perpendicular to the satellite). This study considers the motion of the rigid yo-yo in PHASE 1 and PHASE 2 as a three-dimensional problem and the equations of motion of the system which is derived are solved numerically for several specific cases. The results show that this theory is a sufficient to make clear the motion of the rigid yo-yo in PHASE 1 and PHASE 2. Then some results of the stretch yo-yo feasibility tests are presented. These tests were conducted to prove the concept that the stretch yo-yo is a more accurate despin device than the rigid yo-yo, and to verify the analytical theory. The results of another experiment which was conducted on the rigid yo-yo are also presented. In this case, yo-yo wires were wound around an octogonal cylinder to compare with the case in which yo-yo wires are wound around a right cylinder., 資料番号: SA0125383000},
