Blade assembly on basis of a modular structure for a turbomachine

The invention relates to a blade assembly on the basis of a modular structure, wherein the blade elements comprise at least a rotor blade airfoil, a footboard mounting part (214) and a heat shield. The elements have at its one ending means for the purpose of an interchangeable connection among each...

Beschreibung
Zusammenfassung:	The invention relates to a blade assembly on the basis of a modular structure, wherein the blade elements comprise at least a rotor blade airfoil, a footboard mounting part (214) and a heat shield. The elements have at its one ending means for the purpose of an interchangeable 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 the assembling of the blade airfoil in connection with the footboard mounting part to each other is based on the use of a metallic and/or ceramic surface for the purpose of a friction-locked bonding actuated by adherence interconnecting, or the assembling of the blade airfoil in connection with the footboard mounting part is based on friction-locked means with a detachable, permanent or semi-permanent
