Last week we started to construct our airframe. We made a rudder of a vertical tail and two ailerons. Everyone in this team has experienced treating with balsa woods for the first time. But soon we got used to it, and after an hour we finished making a framework of our rudder and ailerons. Next, we should challenge main wings, but we had difficulty in designing main wings. Our main concept was a tailless aircraft, and we decided to use an inverted camber wing to gain vertical stability. In designing the main wing we used XFLR5 in order to calculate some of stability parameters of the aircraft wing model. First figure shows our provisional wing and next figure is one of the analysis data.
[Achievements] All members of our team participated in this week activities and finally we completed a frame of the rudder and the ailerons. I think that we have gotten used to crafting aircraft parts.
[Problems]
More analysis or research for the inversed camber wing is needed.

 先週からいよいよ機体の製作に取り掛かりました。ひとまず我々の班ではエルロンとラダーを作成しました。全員バルサを触るのは初めてでしたが、完成する頃にはだいぶ慣れた手つきで作業していました。次は主翼にとりかかると生きたいところですが、なかなかシミュレーション上(XFLR5の3次元解析)でいい解析結果を出すのに苦戦しており、もう少し反転キャンバー翼について調べてデザインをブラッシュアップする必要があります。(サーボモーターなどの機材の取り付け位置なども含めて)
