1. An airfoil device for a gas turbine, the airfoil device comprising:
a root section which is mountable to an airfoil disc of the gas turbine, an airfoil element, wherein the root section comprises a platform at which the airfoil element is arranged, wherein the root section comprises a cavity which is surrounded by a radially inner surface of the platform, a first edge side of the root section and a second edge side of the root section, wherein the first edge side and the second edge side are spaced apart from each other along an axial direction of the gas turbine, and a seal strip which is arranged at the inner surface, wherein the seal strip has a first end section, a middle section and a second end section, wherein the first end section is spaced apart from the second end section along the axial direction and the middle section is arranged between the first end section and the second end section, wherein the first edge side comprises a recess into which the first end section of the seal strip is inserted such that the recess surrounds the first end section and fixes the first end section to the inner surface, wherein the root section comprises a supporting lever extending from the second edge side into the cavity such that a free end of the supporting lever forms a contact region with the middle section of the seal strip for fixing the middle section of the seal strip to the inner surface, wherein the supporting lever is further formed such that a further cavity is formed between the inner surface, the second edge side and the supporting lever, and wherein the second end section of the seal strip is arranged inside the further cavity. |
