Abstract
Profil de voilure pour vol à vitesses subsoniques élevées, du type comportant un extrados convexe plat, un bord d'attaque epais et un intrados convexe vers le bord d'attaque et concave vers le bord de fuite. Selon l'invention, ce profil est caractérisé en ce que l'extrados comporte un maximum de courbure au voisinage de sa partie arrière, dans un zone délimitée par des points situés à des distances du bord d'attaque égales à 65 et 90 % de la corde du profil. Réalisation de voilures fixes ou tournantes pour aéronef, présentant un Mach de divergence élevé et une faible traînée.
