A helicopter-type craft is disclosed which obviates the need for the main rotor blades to be variable in pitch to maintain control and provide vertical lift. The aircraft has a main rotor (1) and engine (2) at the top of the aircraft which can be tilted as a unit in a plurality of directions and angles with respect to the body of the crafts. Tilting occurs at a universal joint (3) which may be fixed in position (as depicted) or alternatively mounted on top of a telescoping tower so as to vary the height of the centre of tilt with respect to the body of the craft. Tilting may be effected by handles (4, 5) or alternatively be powered using hydraulic or pneumatic linear actuators. Stability of the craft is maintained by tail rotor (10) powered by a separate engine (11) and possibly by pitch-controllable fins attached to the body of the craft.
Cette invention concerne un aéronef à décollage vertical. Ledit aéronef comporte un ensemble constitué d'hélices et d'un mécanisme rotor (1) disposé au niveau de sa partie supérieure. Ledit ensemble peut être incliné suivant une pluralité de directions et d'angles au moyen d'une rotule autorisant l'inclinaison (3) et il est entraîné en rotation par un ensemble moteur (2) disposé sous ledit ensemble constitué des hélices et du mécanisme rotor (1). On commande la direction et le degré d'inclinaison au moyen de poignées (4, 5). Un ensemble secondaire distinct constitué d'hélices et d'un mécanisme rotor (10), conçu pour assurer la stabilité rotationnelle du fuselage de l'aéronef, est entraîné en rotation par l'ensemble moteur arrière (11).
