Beschreibung
Zusammenfassung:	The plant has a rotor hub that is connected to an annular pitch bearing (16). A blade root of a rotor blade (10) is connected to a pitch bearing via a joining unit. A stiffening element (12) is arranged between the rotor blade and the pitch bearing, where the stiffening element is connected to the pitch bearing via the joining unit. The stiffening element has a shape of a ring, where the stiffening element is realized as a plate and a vat. The stiffening element includes multiple openings, where the stiffening element is made of metal.
