Patent ID: 8052382

Claim:
A rotating turbomachine comprising: a rotor which has at least two rotor blade rows with a plurality of rotor blades, and at least one rotor heat shield with a plurality of heat shield elements arranged axially between two adjacent rotor blade rows; a stator which has at least one stator blade row with a plurality of stator blades arranged axially between two adjacent rotor blade rows; wherein the stator blades have a stator sealing structure on a radially inside portion thereof which is circumferentially closed; wherein the heat shield elements each have a rotor sealing structure at a radially outside portion which is circumferentially closed and which interacts with the stator sealing structure to form an axial seal; a blade radial seal formed between two circumferentially adjacent rotor blades and separating a gas path, through which the rotor blades and the stator blades extend, from the rotor; and a heat shield radial seal positioned between two circumferentially adjacent heat shield elements and separating the gas path from the rotor; wherein the heat shield elements and the rotor blades are matched to each other so that the heat shield radial seal merges without interruption into the blade radial seals of said two axially adjacent rotor blades to form a continuous radial seal from one of said two axially adjacent rotor blades, via the heat shield element, to the other of said two axially adjacent rotor blades; wherein the blade radial seal comprises circumferentially open blade slots positioned in the region of circumferentially adjacent blade roots of the rotor blades, and comprising a plate or a strip sealing element in the blade slots; wherein the heat shield radial seal includes heat shield slots formed in regions of the heat shield elements circumferentially adjacent and which adjoin the rotor sealing structure, the heat shield slots being circumferentially open, and comprising a plate or strip sealing element in said heat shield slots; wherein axial longitudinal ends of the heat shield slots axially align with axially adjacent axial longitudinal ends of the blade slots; wherein at least one of said sealing elements extends from the heat shield slots axially into the blade slots of at least one of the adjacent rotor blades, or extends from the blade slots of the rotor blades of the one rotor blade row axially into the heat shield slots; and wherein adjacent sealing elements axially abut against each other between the axial longitudinal ends of the blade slots, or between the axial longitudinal ends of the heat shield slots, or between both.
