| 摘要 |
The invention is related to a rotor blade (1) with an exterior shell (20) extending in a span and chord wise direction and at least one control flap (4) extending in essentially span wise direction to said exterior shell (20). Load transmission means inside said blade chamber (7) comprise piling type housings (13) respectively with one actuator (8, 9), one flap drive (10, 11) and a longitudinal girder (15). Said at least one piling type housing (13) comprises at least one upper strap (14) and at least one lower strap (14) oriented essentially in said chord direction in between said longitudinal girder (15) on the one side and the support for said at least one actuator (8, 9) on the other side, each of said upper and lower straps (14) being symmetric aligned in chord direction relative to at least two pivot bearings (35, 36). Said upper and lower straps (14) are stiff in chord direction and flexible in span wise direction. |
