The invention concerns a sectional blade for a wind turbine comprising a first and a second blade section extending in opposite directions from a blade joint, and each blade section comprising a spar section forming a structural member of the blade. The blade sections are structurally connected by a spar bridge extending into the first and second blade sections to facilitate joining of the blade sections. The spar bridge comprises a stiffening member protruding from the spar bridge in a chord wise direction of the blade for increasing the edgewise stiffness of the blade, and wherein a part of the surface of the stiffening member is shaped to follow an inner surface contour of the blade. The invention further relates to a method of manufacturing such a sectional blade as mentioned above. |
