The invention relates to a method of reducing the load of a rotor blade 20 of a wind turbine 10 during installation of the wind turbine 10, whereby the rotor blade 20 comprises an aerodynamic device such as a vortex generator 51 or a noise reducer 52. The method comprises the steps of attaching a cover 30 on the rotor blade 20 for covering at least a part of the aerodynamic device before lifting the rotor blade 20 to the top of the tower 112 of the wind turbine 10, and detaching the cover (30) subsequently. The invention furthermore relates to an arrangement (40) comprising the rotor blade (20) of the wind turbine (10) and such the cover (30). 本发明涉及种在安装风力涡轮机（10）期间降低风力涡轮机（10）转子叶片（20）的负载的方法，其中所述转子叶片（20）包括空气动力装置例如漩涡产生器（51）或降噪器（52）。所述方法包括步骤：在将转子叶片（20）提升到风力涡轮机（10）的塔顶部（112）之前将盖子（30）附接到转子叶片（20）上用于覆盖空气动力装置的至少部分，和随后分离盖子（30）。本发明还涉及包括风力涡轮机（10）的转子叶片（20）和此种盖子（30）的布置（40）。
