Abstract
A rotor blade for a helicopter has a blade root for a fastening in the area of the rotor mast and a radially exterior blade tip. An aerodynamic control flap is integrated essentially in the contour of the blade profile is swivellably disposed in the rotor blade between the blade root and the blade tip. The control flap is disposed at its two ends in each case by way of roller bearings on bearing bolts aligned in the span direction of the rotor blade. The bearing of the control flap which is radially on the outside has devices which provide a support with respect to the centrifugal forces of the control flap upon the rotor blade resulting from the rotation of the rotor blade.
