Rotor blade with flap damper actuator

The invention relates to a rotor blade with a flap and flap drive, wherein the lift-generating sheet accommodating the damper actuator with the flap, but the valve remains located outside of the sheet. DOLLAR A object of the invention is to make the installation of a flap with flap drive in a rotor blade so that the structure of the rotor blade is hardly affected, yet a quick check of the functionality of the flap as well as their maintenance and adjustment is possible. DOLLAR A The object is achieved by the characterizing features of claim 1. An alternative solution is offered by the characterizing features of claim 12. DOLLAR A The lift-generating blade (1) has in its structure a blade chamber (10) formed with a forward-direction flag area Opening (100), through the opening (100) at least one housing (16) (10) is insertable and in the blade chamber can be fixed, said housing (16) at least one flap drive (180, 181) and the flap (17) receives. DOLLAR A ensures the invention is that the structure of the rotor blade is not affected. The so-called flap module can be inserted and fixed in the leaf chamber and at any time at standstill of the sheet can be removed and checked in terms of its functionality, with an immediate adjustment is possible.
