Abstract

L'invention concerne un aéronef (10) comprenant un fuselage (100) ayant des premier (110) et second côtés (120) ; un premier rotor (20) positionné du premier côté de l'aéronef et comprenant une pluralité de pales (22), le premier rotor étant mobile entre une première position dans laquelle le premier rotor fournit une poussée de manière générale dans un sens vertical et une seconde position dans laquelle le premier rotor fournit une poussée de manière générale dans un sens horizontal ; un second rotor (30) positionné du second côté de l'aéronef et comprenant une pluralité de pales (32), le second rotor étant mobile entre une première position dans laquelle le second rotor fournit une poussée de manière générale dans un sens vertical et une seconde position dans laquelle le second rotor fournit une poussée de manière générale dans un sens horizontal ; le premier rotor (20) comprenant un premier plan de rotor (200) positionné de manière générale perpendiculairement à un axe de rotation (26) du premier rotor (20), ledit premier plan de rotor coïncidant avec une partie d'une pale (22) du premier rotor ; le second rotor (30) comprenant un second plan de rotor (300) positionné de manière générale perpendiculairement à un axe de rotation (36) du second rotor (30), ledit second plan de rotor coïncidant avec une partie d'une pale (32) du second rotor (30) ; et, lorsque les premier et second rotors sont dans leurs premières positions respectives, les premier et second plans de rotor ne sont pas parallèles, de telle sorte que le premier plan de rotor n'intersecte pas une partie de l'une quelconque des pales du second rotor et de telle sorte que le second plan de rotor n'intersecte pas une partie de l'une quelconque des pales du premier rotor.
