A deformable trailing edge section () of a wind turbine blade (), at least part of said section () being formed in a deformable material. The blade section () comprises one or more cavities () being in connection with or connectable to a fluid source in a way that allows fluid to stream from the fluid source to the cavity or cavities (), so that the shape of the deformable trailing edge section () and thereby the camber of the blade cross-section () is changeable by the pressure of fluid in the cavity or cavities () with insignificant changes of the thickness and chord wise length of the deformable trailing edge section. Furthermore a wind turbine blade () is described, having at least one of such trailing edge section (s) () and to a system () for mounting a blade section () on a main blade () of a wind turbine. In addition a method of manufacturing a deformable trailing edge section () of a wind turbine blade () is disclosed.
