Abstract
A serrated panel (70) for a wind turbine blade is disclosed. The panel (70) is configured to be attached to the trailing edge of a blade to form a plurality of serrations (71) at the trailing edge of the blade. The serrated panel comprises a base part (72) for attaching the panel (70) to the trailing edge of the blade. An exterior surface (78) of the base part comprises a corrugated surface in direction between longitudinal ends of the panel such that the exterior surface comprises crests (82) aligned substantially with midpoints of bases (80) of the serrations (71) and valleys (83) aligned substantially between serrations (71).

A serrated panel (70) for a wind turbine blade, wherein the serrated panel (70) is configured to be attached to a trailing edge of the wind turbine blade to form a plurality of serrations (71) at the trailing edge of the wind turbine blade, wherein the serrated panel comprises:
- a base part (72) adapted for attaching the panel (70) to the trailing edge of the wind turbine blade, the base part (72) comprising:
- a first longitudinal end (73) adapted for arrangement nearest a tip end of the wind turbine blade;
- a second longitudinal end (74) adapted for arrangement nearest a root end of the wind turbine blade;
- a first side (75) adapted for arrangement nearest a leading edge of the wind turbine blade;
- a second side (76) adapted for arrangement farthest from the leading edge of the wind turbine blade;
- an attachment surface (77) adapted for attaching to an exterior surface of the wind turbine blade;
- and
- an exterior surface (78) adapted to face away from the exterior surface of the wind turbine blade when the serrated panel (70) is attached to the wind turbine blade,
- wherein the plurality of serrations (71) extend from the second side (76) of the base part (72), wherein the plurality of serrations (71) comprise a base (79) proximal to the second side (76) of the base part (72), and an apex (80) distal to the second side (76) of the base part (72) with a notional line (81) extending from a midpoint of the base (79) to the apex (80), and
- wherein the exterior surface (78) of the base part (72) comprises a corrugated surface in a direction between the first longitudinal end (73) and the second longitudinal end (74) such that the exterior surface (78) comprises crests (82) aligned substantially with respective midpoints of the bases (79) of the plurality of serrations (71), with valleys (83) of the exterior surface (78) being respectively aligned substantially between serrations (71).
