Abstract (en)
A sealing arrangement for rotating and non-rotating components of a gas turbine is disclosed, which minimizes cooling air losses due to misalignments of an axial seal. The sealing arrangement comprises a circumferential seal (29) and several axial seals (31), and at least one axial seal (31) is positively locked with the circumferential seal (29).
