The present invention relates to a rotor blade (1) which includes an outer shell (20) extending in a spanwise direction and a chordwise direction and at least one control flap (4) essentially extending to the outer shell (20) in the spanwise direction. Each load transferring means inside a blade chamber (7) includes one actuator (8, 9), one flap drive (10, 11) and a piling type housing (13) having a girder (15) of a longitudinal direction. At least one piling type housing (13) includes at least one upper strap (14) and at least one lower strap (14), and the upper strap (14) and the lower strap (14) are arranged between the girder (15) of the longitudinal direction on one side and a supporter relative to the actuator (8, 9) on the other side in the chordwise direction, and the upper strap (14) and the lower strap (14) are arranged symmetrically in the chordwise direction relative to at least two pivot bearings (35, 36). The upper strap (14) and the lower strap (14) may be stiff in the chordwise direction but flexible in the spanwise direction. |
