 Weekly report from team BATMAN. This week we did not make much progress.
 In this report, I will introduce the structure of the plane(especially of the main wing). Please look at the drawing of the structural element. In the drawing, some ribs near the fuselage are not drawn.
 As you can see, this wing does not have the trailing edge. We thought the leading edge and the two spars are enough to maintain the structure, and in order to make the plane lighter, the trailing edge was removed.
 After we complete the wing, we will search the appropriate position of the wing to the fuselage, and fix the wing-body junction to the fuselage finally. By doing this procedure, the plane can obtain the pitching stability.

 チームBATMANの今週の報告です.
 今週は製作作業自体の進捗はほとんどありませんでした.今回は機体(主に主翼)の構造について紹介したいと思います.構造部材の図面の画像を添付します.
 図面では内側のリブについては省略しています.図面を見ていただければわかるかと思いますが,この飛行機の主翼は後縁を省いています.桁が2本あれば強度的に後縁は不要であると判断し,主に軽量化のために後縁は付いていません.翼紙を貼るために,後縁材のかわりに糸を張ります.
 また,主翼の位置をズラしながら最適な取り付け位置を探し,その位置で翼胴結合部を最後に固定する,という手順を取ることで縦の安定性を取ります.来週にはこの最終機が完成する予定です.
