In this week we completed building our plane. On the day before the test flight we finished making substrate and checked if it worked properly. The sensor’s readings was incorrect so we decided first we would do manual control and investigate our plane’s flight characteristics, and next week we would control our plane automatically. In the test flight our plane flew successfully but it had some problems. It tended to fly turn to right because of our plane’s structural characteristics so the day after test flight we revised the main wing. Concurrently we revised substrate.
First of all we relieved because our plane flew successfully. It had substrate so it was heavier than other model planes and we were worried about whether it flew successfully. The success of the test fly enabled us to concentrate on brushing up the substrate.
We took a close look at our plane and found that our plane’s left wing was twisted and left wing’s lift was greater than right wing’s lift. We build imprecise main wing so our plane didn’t fly straight. We found it difficult to build a symmetric and precise wing.

今週は初飛行前日に基盤製作を終わらせ初飛行に臨みました。基盤のセンサーの読みがおかしかったので今週は手動で操縦して飛行特性を調べることにしました。模型飛行機はきちんと離陸し初飛行は成功しましたが右に旋回しがちであることがわかったので機体を修正しました。
初飛行に成功したので基盤など重いものを積んでいても離陸できることがわかりました。機体の修正が終わり次第基盤の修正に注力しようと考えています。
機体が右に旋回しがちだったのは右の主翼がねじれていて迎角が大きくなり左右の揚力が等しくなかったことが一つの原因として考えられます。精密に左右対称な翼を製作することの難しさを知りました。
