翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Parker Variable Wing ： ウィキペディア英語版 Parker Variable Wing The Parker Variable Wing is a wing configuration in biplane or triplane aircraft designed by H.F. Parker in 1920.〔"The Parker variable wing", ''NACA Report 77'', 1920〕 His design allows a supplement in lift while landing or taking-off. The system is depicted in the figure. The figure shows the biplane configuration. The lower airfoil is rigid. The upper airfoil is flexible. At high angle of attack the flow over the lower airfoil will cause the airflow to bend up and create an upward force at the lower surface of the upper airfoil. This upward force will cause the flexible section to be pushed upward. The flexible wing section is held at points A and B. The trailing edge is rigid and can rotate about point B. Due to this effect the camber of the airfoil is increased, and hence the lift it creates is increased. ==References== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Parker Variable Wing」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
