Disclosed is a rotor blade (101) with a first rotor blade section (103) and a second rotor blade section (105). The first rotor blade section and the second rotor blade section are designed to be displaceable relative to each other by means of a control device (109, 113), so a telescopic rotor blade is formed and the rotor blade sections can adopt a minimum position, an intermediate position or a maximum position when displaced. The rotor blade includes a reset device (115), which is setup in such a manner that in case of a functional limitation of the control device, the rotor blade sections take up the minimum position. |
