Abstract
A gas turbine includes a first turbine stage having a first guide blade, a first moving blade and a cooling configuration. The cooling configuration has a first cooling-air feed at the first guide blade for cooling the first guide blade, a first cooling-air supply at a first pressure for supplying the first cooling-air feed, and a second cooling-air feed disposed downstream of the first cooling-air feed for cooling the first guide blade. The second cooling-air feed is supplied with a second pressure lower than the first pressure.
