A blade assembly for a wind turbine rotor is provided, the blade assembly comprising at least two blade sections (1, 2) being longitudinally joinable at respective joining end portions (10, 20) for forming a blade. One of said blade sections has at least one cavity (11) in its joining end portion (10) and the other of said blade sections has at least one protrusion (21) at its joining end portion (20). Said cavity (11) is contractible to a contracted position in a direction which is substantially perpendicular to a longitudinal direction of the blade. |
