Abstract: In order to provide a fixing device which is intended for fixing a component, allows for secure fixing of the component and is of straightforward design, it is proposed that the fixing device should comprise a main body, on which is provided at least one fastening portion for receiving the component, wherein the fastening portion has at least one fixing element which can be inserted into a through-passage provided in the component and, for the purpose of fixing the component, can be at least partially deformed in the through-passage, wherein, as a result of the deformation, the fixing element is in engagement with at least one depression provided on the component and/or with at least one protrusion provided on the component.

Abstract: A gas turbine is provided and includes a compressor, which via an air intake inducts and compresses air; a combustion chamber, in which a fuel is combusted using the compressed air, producing a hot gas; and a turbine, equipped with turbine blades, in which the hot gas is expanded, performing work. A first device is provided in order to cool turbine blades with compressed cooling air. The first device includes at least one separate compressor stage which produces compressed cooling air independently of the compressor.
