摘要：
A blade element (42; 44; 46; 48; 150; 250; 350) for mounting on a wind turbine blade (10) is provided. The blade (10) has a longitudinal direction (L) and a chord extending transversely to the longitudinal direction between a leading edge (18) and a trailing edge (20). The blade (10) has an airfoil profile with a thickness between a suction side and a pressure side along at least a part of the longitudinal direction (L) and with a position of maximum thickness between the leading edge (18) and the trailing edge (20). The blade element (10) has a shape so that, by mounting in a first longitudinal part of the wind turbine blade (10), it changes the profile of the first longitudinal part from a first airfoil profile (100; 200; 300) with an essentially pointed trailing edge (100; 200; 300) and a first chord length (c11; c21; c31) to a changed airfoil profile with a blunt trailing edge (153; 253; 353). The changed airfoil profile is a truncated profile of an imaginary airfoil profile (160; 260; 360) with an essentially pointed trailing edge and a second chord length (c12; c22; c32), which is larger than the first chord length (c11; c21; c31).
