Abstract
A chordwise segment connection structure for wind turbine blades includes: a blade body including a pressure side and a suction side; a leading edge shell and a trailing edge shell formed by the skin of the pressure side and the suction side along the chord length of the blade, the pressure side and the suction side being each provided with a spar cap; and a shear web provided in a cavity of the blade body and extending between the pressure side and the suction side to support the spar cap; wherein the spar caps on the pressure side and the suction side are bonded and fixed to a skin structure where the leading edge shell and the trailing edge shell are spliced, so that the leading edge shell and the trailing edge shell are spliced with the spar caps to form the profile of the wind turbine blade.
