Abstract

L'invention concerne un aéronef (10, 11, 13, 15) à décollage et atterrissage vertical comprenant un fuselage (12) au-dessus duquel est agencé au moins un rotor (24) de sustentation, caractérisé en ce qu'il comprend au moins une première hélice (26) et une seconde hélice (28) chacune portée par une queue (16) et articulée en déplacement sur celle-ci entre au moins une première position dans laquelle elle est apte à servir de rotor d'anti-couple et au moins une seconde position dans laquelle elle est apte à permettre une poussée de propulsion de l'aéronef (10, 11, 13, 15) dans une direction d'avance, les axes (26a, 28a) de rotation desdites première hélice (26) et seconde hélice (28) étant sensiblement coaxiaux lorsque lesdites première hélice (26) et seconde hélice (28) sont dans leur première position.
