Abstract: 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.

Abstract: A blade assembly of a power plant having a modular structure, wherein blade elements include at least one blade airfoil, and at least one footboard mounting part. Blade elements can each have at its one ending a configuration for an interchangeable connection among each other. The connection of the airfoil with respect to other elements can be based on a fixation in radially or quasi-radially extension relative gas turbine axis, wherein the assembling of the blade airfoil in connection with the footboard mounting part is based on a friction-locked bonding actuated by adherence interconnecting, or on use of a metallic and/or ceramic surface fixing blade elements to each other, or on closure configuration with a detachable, permanent or semi-permanent fixation.
