Nice to meet you, I am Goto, a freshman. On this day, I finished the tail wing that I made last time. I feel that 90 minutes in class is a long time when it comes to academic subjects. However, when it comes to something like crafts, where we actually move our hands, 90 minutes seems very short. On this day, the only thing we were able to do was the tail wing. One of the reasons was that the data processing of the main wing ribs was delayed and the main wing ribs were in a state of rate-limiting speed. However, once the vertical tail wing was completed, the quota for the day was fulfilled, so it was not a delay. Also, Morita-sensei made a small airplane for us while we were waiting for the ribs to be cut out. After adjusting the center of gravity several times, we tried to fly it and it flew surprisingly well. As you can see in the photo, we had to attach a lot of weight to the top of the plane, but we learned that it would be better to use a retractable wing to eliminate this problem, and we also learned how to balance the plane using the horizontal tail. I was surprised that I could learn so much from such waste materials. My teammate, who was processing Rib's data, had to stare at his computer the whole time and was unable to participate in building the plane from this scrap wood.
はじめまして、一年の後藤です。この日に前回作った尾翼を最後まで完成させました。授業90分は、学科的なものだとやはり長く感じます。しかし、工作のように実際に手を動かすようなものになると90分が大変短く感じられます。この日もできたのは尾翼くらいでした。原因の一つに主翼のリブのデータ処理が遅れ、主翼リブ律速の状態になってしまったことでした。とはいえ、垂直尾翼が完成したらその日のノルマは達成でしたので、遅れを取ったわけではありません。また、リブが切り出されるまでの時間に小さな飛行機を森田先生が作ってくださいました。何度か重心位置の調整を行い、飛ばしてみると案外飛びました。写真のようにおもりを大量に先頭につけることになったのですが、それを解消するためには後退翼にすると良いことも学べ、また水平尾翼を用いてバランスをとる技術も学ぶことができました。こんな廃材から学びが生まれるとは驚きでした。なお、リブのデータ処理をしていたチームメイトはずっとパソコンを睨みつけることとなり、この廃材から飛行機を作ることには参加できませんでした。ありがとうリブやってくれて
