Abstract: A turbine secondary air system seal arrangement (62). The arrangement comprises a first seal land (70) facing radially inwardly; a second seal land (80) facing radially outwardly; and first labyrinth seal teeth (76) directed radially outwardly to seal against the first seal land (70). Also second labyrinth seal teeth (78) directed radially inwardly to seal against the second seal land (80). The first seal land (70) is configured to move radially relative to the second seal land (80) or the first seal teeth (76) are configured to move radially relatively to the second seal teeth (78) to accommodate differential movement of the lands (70, 80) and teeth (76, 78) during use of the seal arrangement (62).
