Abstract

La présente invention concerne les ailes supercavitantes mixtes pour voilure immergée. Une telle aile comporte une partie de corps avant 4 et une partie de corps arrière 6 formant une unité, l'extrados de l'aile présentant un redan 8, situé sensiblement à la moitié de la corde géométrique du profil, et l'intrados présentant également un redan 9 situé sensiblement aux 2/3 de la corde du profil de façon à réaliser des points de décrochement stables en vitesse élevée, la partie arrière 6 étant alors entièrement inscrite entre les lignes de jet de la partie de corps avant, celui-ci présentant un extrados noyé. Des moyens d'admission d'air Il, 12, 12' communiquent avec la base des redans 8 et 9 pour provoquer une ventilation de la partie de corps arrière aux vitesses intermédiaires. Application aux hydroptères de deuxième génération.
