Abstract
Official abstract text for this publication.
Also provided is a method for applying the tape to rotor blades and a rotor blade protected by said protective tape.
First claim
Opening claim text (preview).
What is claimed is: 1. A rotor blade of a wind turbine protected from erosion, the rotor blade comprising: a leading edge that predominantly faces the wind; a trailing edge opposite the leading edge; and a protective top layer covering and bonded to the leading edge of the rotor blade by an adhesive bottom layer, wherein the top layer has a continuous surface (S) that is outwardly curved or outwardly trapezoidal, wherein the protective top layer and the adhesive bottom layer have a cross-sectional profile having an inner section between a first edge lateral section and a second edge lateral section, wherein the inner section comprises up to 90% of the width of the top protective layer, and wherein the inner section has a thickness (Ti), the thickness of the first edge lateral section is T1, and the thickness of the second edge lateral section is T2, wherein Ti is greater than each of T1 or T2, and wherein the thickness (T1 or T2) of at least one edged lateral section is at most 600 μm and the thickness of the inner section (Ti) is at least 330 μm. 2. The rotor blade of claim 1 , wherein the inner section is disposed over the leading edge and the first and second edge lateral sections extend toward the trailing edge of the blade.
