ABSTRACT:
A rotary wing flying craft has at least two rotor blades rotatable around a normally vertical axis, at least one driving means for driving the rotor blades and a cabin for receiving loads. In flowing direction of the air stream generated by the driving means, an air channel is formed in the cabin and penetrates the same, with the inlet opening of the air channel provided on the top side of the cabin and the outlet opening of the air channel provided on the bottom side of the cabin. Two spatially superposed guide vane systems are provided in the air channel, one of these guide vane systems being formed as a guide vane ring loosely rotatably supported in relation to the driving means, on which ring the rotor blades are mounted, while the other guide vane system is provided for the compensation of the counter torque.
