A rotor (8, 8', 106''', 106'''', 106''''', 106'''''') for an aircraft (1, 100) is described, comprising an input shaft (10, 108) rotatable around a first axis (C, I); an output member (15, 112) rotatable around a second axis (D, J); a coupling element (20, 20', 20'', 20''') functionally interposed between the input shaft (10, 108) and the output member (15, 112) and adapted to transmit the motion from the input shaft (10, 108) to the output member (15, 112); the coupling element (20, 20', 20'', 20''') is configured to allow, in use, a fixed or variable inclination between the respective first and second axes (C, I, D, J); the coupling element (20, 20', 20'', 20''') comprises at least a first corrugated element (21, 22, 25, 120''', 121''', 120'''', 121'''', 122'''') made of an elastically deformable material; the first corrugated element (21, 22, 25; 120''', 121'''; 120'''', 121'''', 122'''') allows the inclination through elastic deformation.

    Selon l'invention, un rotor (8, 8', 106''', 106'''', 106''''', 106'''''') pour un aéronef (1, 100) comprend un arbre d'entrée (10, 108) pouvant tourner autour d'un premier axe (C, I) ; un organe de sortie (15, 112) pouvant tourner autour d'un second axe (D, J) ; un élément de raccord (20, 20', 20'', 20''') fonctionnellement interposé entre l'arbre d'entrée (10, 108) et l'organe de sortie (15, 112) et conçu pour transmettre le mouvement de l'arbre d'entrée (10, 108) à l'organe de sortie (15, 112) ; l'élément de raccord (20, 20', 20'', 20''') étant conçu pour permettre, lors de l'utilisation, une inclinaison fixe ou variable entre les premier et second axes respectifs (C, I, D, J) ; l'élément de raccord (20, 20', 20'', 20''') comprenant au moins un premier élément ondulé (21, 22, 25, 120''', 121''', 120'''', 121'''', 122'''') composé d'un matériau déformable élastiquement ; le premier élément ondulé (21, 22, 25, 120''', 121''', 120'''', 121'''', 122'''') permettant l'inclinaison par déformation élastique.
