2016 summer semester Flying Robot Project 12th Team BJune 30, 2016

620

This week our team have accomplished two big tasks. One task was an improvement of main wings. Although our main wings were completed, we found that the main wings were weak when they received the force to be twisted. To make them stronger, a string was attached between frames of main wings. The other task was to fix a motor and servomotors on the body. We made balsa boxes that tie the servomotors to the body and placed them under main wings. Also, a propeller was attached to the motor at the head of the aircraft and it was tied with a rubber band.
The main achievement of this week was that almost all parts of aircraft was fixed and the shape of aircraft was completed. Also, moving the balsa boxes and main wigs on the body, the location of the center of the gravity came to the perfect position.
However, our aircraft still has some problems. The string that connects servomotors and the horizontal tail disturbs the movement of the vertical tail. And the length of cables that connects servomotors and receiver is short. So we need to solve these problems next week.

今週我々のチームは2つの重要な作業をしました。1つめは主翼の改善です。先週までに作成した主翼はねじれの力に対して強度が不足していたので、主翼の前縁と後縁の間に糸を張ることで強度をあげました。2つ目は諸部品の胴体への固定です。バルサやベニヤ板を活用してサーボモーターやプロペラを機体に固定しました。
今週の活動で機体はほぼ完成し、各種部品の固定も完了しました。重心の位置も調整し終わりました。
残る問題点としては、サーボモーターと尾翼舵面をつなぐ糸が干渉してしまうことや、サーボモーターのコードが短いために受信機と接続できない、などといったことが挙げられるので来週以降の活動で修正していきます。
