Abstract

L'invention concerne une pale de rotor d'autogire destinée à produire une sustentation autorotative, présentant une zone profilée intérieure (9) côté pied de pale, laquelle possède un premier profil (21c), une zone profilée principale (10) côté bout de pale, laquelle possède un deuxième profil (21e) différent du premier profil (21c), et un profil de profondeur (22) diminuant de façon monotone dans la direction longitudinale de la pale de rotor d'autogire (1), de la zone de pied de pale (2) vers le bout de pale (3). La pale de rotor d'autogire (1) présente une torsion possédant un profil de torsion (23) diminuant de façon monotone de la zone de pied de pale (2) vers le bout de pale (3), le profil de torsion (23) présentant un pas variable dans la zone profilée intérieure (9) et/ou la zone profilée principale (10) de telle manière que le profil de torsion (23) est courbé de façon concave dans cette zone (9, 10).
