Abstract
a. L'invention concerne une aile portante à profil hypercritique prévue pour un nombre de Mach allant jusq'à 0,85 et une épaisseur de profil maximale d/l = 0,13 +- 20%. b. Cette aile est caractérisée en ce que la position de l'épaisseur maximale de l'extrados est (x/l) mo = 0,42 +- 10 %, la position de l'épaisseur maximale de l'intrados est (x/l) mu = 0,3 + 25 % ou - 10 % la courbure de l'extrados variant avec x/l avec un point d'inflexion pour 0,5 <= x/l <= 0,6. c. L'invention est applicable aux ailes portantes à profil hypercritique.
