Abstract

L'invention concerne une tuyère de propulsion pour moyens de transport dans l'air et dans l'eau. La partie antérieure de la paroi de la tuyère 2 s'évase vers l'extérieur. Venant d'une chambre 1 entourant la tuyère, le fluide sous pression est envoyé dans la tuyère par une fente 4 ménagée en avant de la surface courbe de manière que le fluide soit éjecté tangentiellement suivant un angle aigu par rapport à la direction du courant de sortie. Le bord antérieur de la fente ne fait pas saillie à l'intérieur de la gorge 6 de la tuyère. Application aux aéroglisseurs, aux aéronefs et aux navires. Le niveau de bruit et l'encombrement sont très réduits par rapport à la technique antérieure.
