Sealing arrangement between stator blades and rotor of a high pressure turbine

摘要

The high pressure gas turbine has a turbine disk (1) with running paddles (2) and guide paddles (3). A side zone (5) is formed between the turbine disk and a guide paddle rim (4). A seal (8) is formed in the axial direction between the guide paddle platform (6) and the running paddle platform (7) as a labyrinth seal, radially outwards against a main gas channel (9). Alternatively, the seal can use bristles.
