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.

Abstract: Disclosed is a wind turbine blade assembly and a method for its manufacture. The wind turbine blade assembly comprises a leading edge, a trailing edge, a blade shell with a trailing portion, and a flatback profile component. The trailing portion has an outwardly curving arc shape and the flatback profile is positioned so as to cover the trailing portion of the blade shell.
