In this week, we drew the exact size drawing of building a vertical tail and elevons. Following advice of TAs, we decided to make a larger ladder than that of the final manuscript. We are going to construct the frame of the wings following this plan. The structure of these wings is relatively simple, so we decided to make them first. However we have not made a plan of making the main wing because the structure of this wing seems to need some improvements. Concretely, we may have to find out more ideal shape of the wing because the result of analysis of the present wing in “3D analysis of XFLR5” had some problems. We decided that we should not attach importance to the result, but we will continue the analysis until next week. Moreover, the main wing was separated two parts and we had to decide how to connect them.
In this week, we finished making drew the exact size plan, this is only a work we were able to do in this week. This is a small advance, but the plan will allows us to make great improvement in next week.
Our main task of next week is constructing the frame of elevon and vertical tail and making the exact size drawing of the main wing. In next week, it is expected that we will be busy and have difficulty finding time to do these tasks. However, next week will be one of the most important weeks of this project and we must make a greatest effort.

今週は、エレボンと垂直尾翼の実寸図面を書いた。垂直尾翼のラダーに関しては、TAのアドバイスに従い若干大きくすることにした。来週はこれらの図面を基に、実際翼を組み立ててゆく予定である。比較的単純な構造である故、工作初心者には兆度いい練習になるはずだ。
　主翼に関しては改善の余地がある故、未だ図面をしたためていない。具体的には、解析結果に不安があるのと、二つに分割した部分を如何にして接続するかがまとまっていないのである。解析に関しては、あまり重視しない方針ではあるが一応来週までは続けようと考えている。
今週は、実寸図面の作成くらいしかできなかったが、一応これがあれば、作業ができるので、来週の作業の前進にはつながる。
　来週の目標は垂直尾翼とエレボンの完成及び主翼の図面の作成である。来週は各々多忙を極め、このプロジェクトに関連する作業をなす事が甚だ難しくなると予想されるが、来週こそ最も重要な週となると思う故、最大限の努力をしていきたいと思う。
