1. A wind turbine blade (10, 610) for a rotor of a wind turbine (2) having a substantially horizontal rotor shaft, said rotor comprising a hub (8), from which the wind turbine blade (10, 610) extends substantially in a radial direction when mounted to the hub (8), the wind turbine blade (10, 610) having a longitudinal direction (r) with a tip end (14) and a root end (16) and a transverse direction, the wind turbine blade (10) further comprising:
a profiled contour (40, 42, 50) including a pressure side and a suction side, as well as a leading edge (18) and a trailing edge (20) with a chord having a chord length extending there between, the profiled contour, when being impacted by an incident air-flow, generating a lift, wherein
a surface mounted device (70, 70′, 170, 270, 370, 470, 570, 670, 770) is attached to a surface of the wind turbine blade (10), wherein
the surface mounted device (70, 70′, 170, 270, 370, 470, 570, 670, 770) is attached to the surface of the wind turbine blade (10, 610) via at least a first attachment part (77, 77′), which is connected to a part of the surface mounted device (70, 70′, 170, 270, 370, 470, 570, 670, 770), wherein
the attachment part (77, 77′) comprises a flexible housing (80, 80′, 680, 780) that forms a cavity (81, 81′, 681, 781) between at least the housing (80, 80′, 680, 780) and the surface of the wind turbine blade (10, 610), and wherein
the cavity (80, 80′, 680, 780) is filled with an adhesive that provides an adhesive bonding to the surface of the wind turbine blade (10, 610).
