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.
L'invention concerne une pale de rotor (22) pour une éolienne (10), laquelle pale de rotor (22) comporte au moins une cavité (28). Scellée de façon à être étanche au gaz, la cavité (28) est remplie de gaz, en particulier d'air, afin de précontraindre la pale de rotor (22), la pression du gaz étant supérieure ou inférieure à la pression d'air moyenne prévue au point d'utilisation de la pale de rotor.
