This week, we began to cut out the parts and build the plane, from the plans and concept designs. Blended wing body wings` accuracy of the shape is extremely important, due to the lack of the horizontal tail wing to stabilize and adjust the attitude, so a special platform was decided to be built to achieve the exact angle of attacks for the each rib, and the camber shapes. The jig consists of accurately sized supports cut out from plywood plates via laser cutters, placed on graph paper with markings, on where the each supports and ribs should be placed. The wing will be assembled on the supports of the jig as shown in the picture. The airfoil ribs are made out of balsa wood, and the main spar will be constructed into a sandwich structure with balsa and plywood. The bonding of the parts were done by using instant glue. Our goal is to complete the main structure of the wing and begin placing the electronic parts such as the motor, receivers and servos, plus begin cutting out the parts to put these together on the plane … all during the next week !
Still lots to be done……….. 今週は、いよいよ設計案および図面から実際に部品を起こし、組み立てる作業を開始致しました。無尾翼機は名の通り、独立した尾翼がないため、安定した飛行には主翼の工作精度が非常に重要であり、設計通りのねじり下げおよびキャンバーを再現するために、リブを主桁およびストリンガーに接着するための専用の治具を製作することにしました。治具は、作業台に方眼紙を固定し、その上にレーザーカッターで切り出した正確な高さのベニヤ製サポートを所定の位置に配置したもので構成され、写真の様にこれの上で翼を組み立て接着していきます。リブの材料は軽量なバルサで、主桁はバルサとベニヤのサンドイッチ構造を採用し、接着には瞬間接着剤を用いました。来週あたりに主翼の主な構造の完成を目指し、モーターや受信機、サーボ等の配置や、固定用パーツ制作に入る予定です！まだまだ先は長そうです。。。。。
