This week we made progress especially in making the main wing. We had prepared the front and rear flame of it and we almost completed the whole wing flame. We had planned to cut off the rear parts of some ribs so as to eliminate the total weight, but along with an advice that it might be better to glue each rib and each rear flame to ensure the rigidity of the wing, we redesigned the ribs and put them together. We also archived on cutting the adequate wing-fuselage mount. In addition, as our plane has longer fuselage than the rods supplied as materials, we extended a rod by connecting to another.
Through the work in this week, we cooperated mostly in making the main wing, which required many hands. It was also an achievement that we could acquire how to put together a three-dimensional structure as precisely as possible and gain knowledge of the use of the stronger adhesive through connecting carbon rods.
However, we could not finish the whole wing and, through the work, often rely on TAs too much. Moreover, we could not spend much time discussing how to make better the structure.

今週、当班は特に主翼製作に進捗がありました。既に前後縁は製作しており、今週でほぼ翼構造は完成しました。当初、軽量化のためいくつかのリブの後方を切り落とし取り付けることにしていましたが、翼の剛性を保つためには各リブと後縁を接着するほうがいいだろうとの助言があったため、リブを再設計した上で組み立てを行いました。また翼胴結合を最終設計して切り出し、素材より長い胴体を素材ロッド接着により延長した部材で製作しました。
全体を通して、特に人手の要る主翼構造製作において最も協力して作業できました。三次元的構造をできるだけ正確に作る方法や、強力なエポキシ接着剤の使用法を把握できたことも成果だったと思います。
しかしなお翼全体の製作は完了しておらず、またしばしばTAの方々に製作を頼りきりになる場面も多くあり、加えて構造改良についてしっかりと班内で議論する時間を取っていなかった点は十分反省すべきであると考えます。
