Beschreibung
Zusammenfassung:	A blade assembly having a modular structure, wherein the blade elements include at least a rotor blade airfoil, a footboard mounting part and a heat shield. The elements each have at its one ending an interchangeable connection for connection among each other, wherein the connection of the airfoil with respect to the other elements is based on a fixation in radial or quasi-radial extension compared to the rotor axis of the turbomachine. The assembling of the blade airfoil in connection with the footboard mounting part is based on a force-fit or form-fit fixation, or on use of a metallic and/or ceramic surface for the purpose of a friction-locked bonding actuated by adherence interconnecting, or on friction-locking with a detachable, permanent or semi-permanent fixation.
