Abstract
The present invention relates to a method of manufacturing a wind turbine blade comprising the steps of manufacturing a pressure shell halves and arranging a spar structure (62) within one of the shell halves. The spar structure (62) comprises two parts releasably coupled to each other. The method results in a segmented wind turbine blade for easy transportation and re-assembly.

A method of manufacturing a wind turbine blade having a profiled contour including a pressure side and a suction side, and a leading edge and a trailing edge with a chord having a chord length extending therebetween, the wind turbine blade extending in a spanwise direction between a root end and a tip end, the method comprising manufacturing a pressure side shell half and a suction side shell half over substantially the entire length of the wind turbine blade, closing and joining the shell halves for obtaining a closed shell, cutting the closed shell along a cutting plane (69) substantially normal to the spanwise direction of the closed shell to obtain a first and a second blade segment (70), each blade segment comprising part of the pressure side shell half and part of the suction side shell half, separating the first blade segment (68) from the second blade segment (70) and joining and sealing the first blade segment (68) to the second blade segment (70) for obtaining the wind turbine blade.
A spar structure (62) for a wind turbine blade, the spar structure comprising a first part (64) and a second part (66), the first and second part (66) being releasably coupled to each other, wherein the second part (66) of the spar structure (62) comprises a spar member (67), such as a spar beam or a spar box, the spar box comprising at least one spar beam and at least one spar flange, and wherein the first part (64) of the spar structure (62) comprises a sheath member for at least partly enclosing the second part (66) of the spar structure (62).
