The invention relates to the rotor blades of a gyrocopter. It allows the takeoff distance to be shortened considerably, even to the extent that a jump takeoff is possible. Along a rotor blade of the rotary wing there extends a rod (2.2), to the end of which on the rotor head side a drive can apply a torque parallel to the longitudinal direction of said rod and counter to the angle of attack of the rotor blade. In a region along its length at a distance from the end on the rotor head side, the rod (2.2) is supported on the rotor blade against relative rotation about an axis parallel to its longitudinal direction and counter to the angle of attack. The rotor blade can be elastically deformed by the torque that can be applied by way of this support, in such a way that its average angle of attack is reduced or increased by several angular degrees with respect to the average angle of attack when the rotor blade is not subjected to this torque. |
