81784111 ABSTRACT A rotary wing aircraft includes a non-rotating structural backbone formed to accommodate power and signal transmission components. First and second variable pitch rotor blades are connected to the backbone and supported for rotation about an axis of rotation in first and second rotor planes of rotation and first and second pitch controllers are connected to the backbone for controlling a cyclic pitch of the first and second rotor blades. An engine or motor is located below the second rotor plane of rotation and configured to provide power to drive the first variable pitch rotor blade about the axis of rotation. A torque tube extends through an interior of a central column of the backbone and is configured to transmit rotational motion from the engine or motor to the first variable pitch rotor blade to drive the first variable pitch rotor blade about the axis of rotation.

L'invention porte sur un véhicule à ailes tournantes, lequel véhicule comprend une structure de corps ayant un cur ou une ossature tubulaire allongé, et un système de rotors coaxiaux à contre-rotation ayant des rotors, chaque rotor ayant un moteur séparé pour entraîner les rotors autour d'un axe de rotation de rotors commun. Le système de rotors est utilisé pour déplacer le véhicule à ailes tournantes selon un vol directionnel.
