ABSTRACT:
The invention relates to a rotor blade (22) for a wind energy installation (10), with the rotor blade (22) having at least one cavity (28). The cavity (28) is sealed to be gas-tight and is filled with gas, in particular air, in order to prestress the rotor blade (22), with the pressure of the gas being greater than or less than the average air pressure to be expected at the point of use of the rotor blade.
