The turbine has a first blade (2) directed along a blade axis with a head region and a bounding blade plate region. The turbine component (5a,5b) extends along the rotation axis (1). There is a main flow path (6) with a main flow direction (7) and a gap flow path (8) which has a flow connection to the main flow path and which leads via a seal gap (9) between the head region (4a,4b) and the turbine component. A second turbine blade (11) arranged downstream of the first turbine blade extends along a blade axis and has a blade plate region (13b) and a foot region (12b). Its foot region is attached to the turbine component. The gap flow path has a bounding surface downstream of the gap viewed in the main flow direction and is inclined in the middle at an acute angle to the rotation axis. One blade plate region (13a) has a radial height offset (14) relative to the blade plate region bounding (13b) on the foot region of the second turbine blade. |
