The invention relates to a blade−hub for a wind turbine. The blade−hub is provided with rib−stiffeners, which extend from a flange of the blade hub and inwardly along the plane of a hole delimited by the flange. The rib−stiffeners aid in providing a sufficient stiffness of the blade−hub, especially large hollow blade−hubs for the constantly increasing size of wind turbines. The rib−stiffeners are sized according the need for proper stiffness of the blade−hub, but also in consideration of the needs for proper access to the blades attached to the blade−hub, i.e. access to bearing bolts and access to the interior of the blades.
