Abstract

A wind turbine rotor blade comprising • a blade root, • a blade tip, • a blade length, • a tip section including the blade tip and extending over 5 % of the blade length or less, • a main section extending over 50 % of the blade length or more and ending at the tip section, and • a cross section having, at each position along the blade length, - a chord and - a maximum thickness at a maximum thickness chord position, • wherein the wind turbine rotor blade is designed to be operated with variable pitch angle, a design pitch angle being the angle at which the wind turbine rotor at a design tip speed ratio extracts maximum power from the wind, • wherein in a projection onto the rotor plane of the wind turbine rotor blade arranged at the design pitch angle, the maximum thickness chord position throughout the main section is offset from the pitch axis towards the leading edge.
