…The series of airfoils created by the American NACA (the predecessor of NASA) is representative of these. In the early 1940s, laminar airfoils were put into practical use. This airfoil kept the boundary layer of the airflow on the wing surface laminar as far back as possible, delaying the change to a turbulent boundary layer and reducing friction resistance. This airfoil became the mainstream for subsequent subsonic aircraft. … *Some of the terminology that mentions "airfoil" is listed below.

…なかでもアメリカのNACA(NASAの前身)が作った翼型の系列はその代表である。40年代初めには層流翼型laminar airfoilが実用化された。これは翼表面の気流の境界層をなるべく後方まで層流に保ち,乱流境界層に変わるのを遅らせて摩擦抵抗を減らした翼型で,その後の亜音速機はこの翼型が主流となった。… ※「airfoil」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
