Abstract

The invention relates to a rotor blade (5) of a wind turbine (1), comprising a rotor blade shell (7) and a blade root (6) for fixing the rotor blade (5) on a hub (4) of the wind turbine (1). The rotor blade (7) has at least one cavity (8), at least some portions of which can be accessed. The invention is developed in that the rotor blade shell (7) has a closable exit opening (13).
