Weekly report from team B. What we did this week was to improve our basic airplane design based on comments we received for our presentation on the first three-view drawing. As for the wings, the trailing edges originally were perpendicular with the body, but they are now on a slight angle so that main supporting beam (for wings) can be installed without bending (the leading edges are on an angle as well and so our wings are tapered). We also increased the dihedral angle from 5 degrees to 12 degrees as it was not big enough. Aside from changes on wings, we diagonally cut off the bottom part of the rudder. Such an alteration was necessary to free up some space for elevator movement. We are now looking into reducing the total length of the airplane from 1200mm to somewhere around 1000mm. This way, the body can be crafted from a single carbon pole and not two joined poles (the maximum length of one carbon pole is 1000mm).

今週はTAの方々の意見等を参考に初期三面図の修正に取り組みました。まず、主翼の前縁は胴体に対して角度が付いているのに後縁が真っ直ぐだと、桁を通すときに途中で曲げなければならず作りにくいということから、後縁にも角度をつけました。また、主翼の上半角も5度では足りないというご意見を頂き、これを12度まで増やしています。主翼以外の部分については、ラダーの下部分を斜めに削りエレベーターと接触しないようにしました。現在は機体の全長を1200mmから1000mm程度まで短くし、胴体を2本のカーボンを繋げたものでなくカーボン1本にすることを検討中です。
