An arrangement for a horizontally and vertically flying aircraft of the type that for vertical flight has rotors that form a lifting area such as in a helicopter, and where the rotors are retracted within a rotor disc (4) during horizontal flight. The rotors (8) are supported with fixed pitch in the rotor disc (4). The centre point of the lifting area is arranged to be capable of being shifted in an xy plane, or means are provided to be brought at determined points within the lifting area of the rotor disc (4) to break the lifting capabilities in the effective rotor disc for manoeuvring and counteracting differential lift during propulsion of the aircraft in vertical flight and on the transition from vertical to horizontal flight.

L'invention concerne un agencement destiné à un aéronef volant horizontalement et verticalement du type qui présente, en vol vertical, des rotors formant une zone de sustentation, comme, par exemple, dans un hélicoptère, et se rétractant dans un disque de rotor (4) en vol horizontal. Ces rotors (8) sont supportés par un pas fixé dans le disque du rotor (4). Le point central de la zone de sustentation est disposé de manière à pouvoir être changé dans un plan xy, ou des moyens peuvent être amenés à des points prédéterminés dans la zone de sustentation du disque de rotor (4) afin d'interrompre les aptitudes de sustentation dans le disque de rotor effectif en vue de manoeuvrer et de contrebalancer la sustentation différentielle pendant la propulsion de l'aéronef en vol vertical et pendant la transition du vol vertical en vol horizontal.
