An aircraft with prefer-ably coaxial counter-rotating sustaining rotors (4,5) comprises in combination: means (21, 27, 24, 25, 29, 34) for varia-tion of the collective pitch, i.e., for apply-ing simultaneously one and the same variation to the incidence of all the blades of said rotors; and means (1, 2, 3) for controlling the attitude and direction of flight, which by generating appropriate aerodynamic forces via the sustaining ro-tor wind eliminate the need for the pres-ence of means for variation of the cyclic pitch of the blades of the rotors them-selves.
L'invention porte sur un aéronef avec des rotors de croisière de préférence coaxiaux et contrarotatifs, lequel aéronef comprend en combinaison : des moyens pour une variation du pas collectif, c'est-à-dire, pour appliquer simultanément une et une même variation sur l'incidence de toutes les pales desdits rotors; et des moyens pour commander l'attitude et la direction de vol, qui, par génération de forces aérodynamiques appropriées par l'intermédiaire du vent de tourbillon d'aval, éliminent le besoin de prévoir des moyens pour une variation du pas cyclique des pales des rotors eux-mêmes.
