Abstract
The invention relates to a rotor comprising a rotor shaft, a rotation torque transmission element which is mounted thereon and at least one element of the plate-shaped rotor head whose axis of rotation extends therethrough. Said rotor is provided with two groups of different arms. The first group consists of the flexible rotor blade connection arms which remove centrifugal forces and to which a respective blade can be fixed. The second group consists of flexible connection rotor arms which are devoid of centrifugal force to which the elements of the plate-shape rotor head can be rotationally fixed by means of the rotation torque transmission element.

1-13. (canceled)
A hingeless rotor defining an axis of rotation, comprising
- a rotor mast;
- a torque-transmission element disposed rotationally fixed with respect to the rotor mast;
- and
- at least one plate-shaped rotor head element having a first group of arms and a second group of arms, the axis of rotation of the rotor passing through the at least one plate-shaped rotor head element, wherein the first group of arms includes a plurality of bending-flexible rotor blade-connection arms that dissipate centrifugal forces, each of which is connectable to a rotor blade, and wherein the second group of arms includes a plurality of bending-flexible rotor mast-connection arms that are free of centrifugal force and connecting the plate-shaped rotor head element to the torque-transmission element.
