Weekly report from team B. In this week's class, we presented our structural three-view drawing which we drew after thinking about suggestions and advices we got in the last week's presentation. As for this week's presentation, the TAs' comments on it can be summed up in three main points: the tailplane needs more structural support (so more ribs), having only one junction point for the wing and the body is not enough to stabilize the entire wing, and the wing is so thick that it may increase air resistance. We worked on the tailplane structure right away, and now the tailplane has two extra supporting ribs in parallel with the body. We took away one rib each from pairs of ribs that are making a cross to counter the weight gain. Right now, we are still thinking about how the shape of the wing and the wing-body junction should be improved.

今週の授業では先週の変更点を踏まえて描いた構造三面図について発表しました。TAの方々にご指摘頂いた点は主に、水平尾翼の構造材が少ない、翼胴接合が一箇所のみでは固定するには厳しい、主翼が厚翼過ぎるので抵抗が増えるかもしれない、の3点でした。水平尾翼については胴と水平に配置する構造材を増やして、より強固にしました。その一方で、構造材が十字になっていたところから一本ずつ減らしているので、重量はそれほど変わっていません。主翼の翼形や、翼胴結合はまだどのように修正すればよいか検討している最中です。
