This week our team made a third draft of the 3-view drawing for our plane. Last week we made a major change to the design of our plane. Due to these changes, we were told that our plane would be quite hard to make, and control. However, our concept was to make a simple plane that can be controlled easily. Therefore we made some slight changes from our second design to make our plane go by our concept. To be specific, we changed the main wing to a normal gull wing from a gull wing with two joints. Due to this improvement, our plane has become much stronger and easier to make. We also made the dihedral angle bigger to make our plane more roll stable.
This week we also started to search on how to make our plane automatically circle. We found out that a triaxial accelerometer and a gyroscope will be needed to detect our plane’s position. We started to test these two components using arduino, and were successful in detecting　the roll and pitch angle using an accelerometer.
During this week we were able to design a plane with a fashionable design that should be able to fly slowly, thanks to the advice from our mentors.
This week we were also able to detect the angular velocity of a breadboard, using a gyroscope, but we still are not sure how to use this data. There is also a need to search on how to control our plane using only the rudder and the elevator.

今週は初期三面図のver3を作成しました。前回の大幅変更に対し、TAさんからたくさんのアドバイスをいただきました。それらのアドバイスを参考に、自動操縦が可能でオーソドックスというコンセプトに沿うように機体に幾つか変更を加えました。主翼を二つの折り返し点を持つ複雑な形状から通常のガルウィングにし、主翼の形も単純な楕円翼に変更しました。また。ロール安定性確保のため、上反角を増やしました。
　今週は自動旋回を行うための電気回路に関することの調査を行いました。その結果、三軸の加速度センサとジャイロが必要であることがわかり、加速度センサを用いて機体の傾きの検知に成功しました。 ジャイロセンサは使い方はわかったものの、取得したデータの利用の仕方がまだ不明です。また、ラダーとエレベーターのみで機体を制御する方法も調べる必要があります。
