A flap arrangement (20) for a wind turbine rotor blade (5) is described. It comprises a leading edge (109), a trailing edge (111) and a chord line (101) between the leading edge (109) and the trailing edge (111). The flap arrangement (20) comprises a support portion (21) and a flap portion (22) which is passively moveable with respect to an angle (²) between a surface normal (34) of a surface (41) of the flap portion (22) and the chord line (101). The support portion (21) and the flap portion (22) are positioned relatively to each other such that the support portion (21) provides a limit to the movement of the flap portion (22). |
