Last week the main wing was almost completed, but twisting both ends of it we discovered that the main wing’s torsional rigidity was insufficient. Moreover Mr.Kanegawa pointed out that the inclination of the wing tip was so sharp that it could cause wing tip stall. So we decided to lower the trailing edge and change the place of inserting diagonal components, and rebuilded wing tip to adhere it to girder as horizontal as possible. Then we twisted the main wing again and confirmed that the torsional rigidity was improved. We attached ailerons on the trailing edge in the remaining time.
Because we dealt with the lack of torsional rigidity promptly, we could improve the main wing in a short time. We planned to make our model plane as soon as possible so it was good that the main wing was almost completed. The rest is pasting wing paper.
Before we paste wing paper , now we are discussing how to connect the thread of the linkage. We are not sure if the horn should be closer to the trailing edge. Mechanically it would be better if it is closer to the trailing edge ,but if it is close to the trailing edge there is a danger of interfering with the trailing edge. By next week we are going to decide the place of the horn.

先週に主翼は大体完成しましたがねじってみたところ曲げ剛性が不足していることがわかりました。また金川さんに翼端失速の恐れがあるとアドバイスをいただいたので合わせて翼端も作り直しました。後縁の場所を下げて斜め部材を適切に入れた結果ねじり剛性が向上しました。
　比較的早期に曲げ剛性が不足していると分かったので作り直すのも手間がかからずに済んでよかったです。できるだけ早く機体を完成させて自動操縦の調整に移る予定なので予定が遅れずに済みました。
　エルロンを後縁に設置した後でリンケージの糸をどのようにつなげるかを今考えています。現段階ではホーンは後縁から離れた部分に配置されていますがそれでは機構を考えると角度変化が小さくなる恐れがありかといって後縁に近いと干渉しないか心配です。いずれにせよ来週までには結論を出す予定です。
