Abstract
An airfoil device for a gas turbine has a root section mountable to an airfoil disc and an airfoil element. The root section has a platform at which the airfoil element is arranged. The root section has a cavity surrounded by an inner surface of the platform, a first and a second edge side of the root section. A seal strip is arranged at the inner surface, wherein the first edge side has a recess into which a first end section of the seal strip is arranged. The root section has a supporting lever extending from the second edge side into the cavity. The supporting lever is formed such that a further cavity is formed between the inner surface, the second edge side and the supporting lever, wherein the second end section of the seal strip is arranged inside the further cavity.
