摘要:
A hula seal as disclosed extends in a circumferential direction, a radial direction and an axial direction relative to a central axis.The hula seal includes a first leaf extending from the first edge region to the second edge region and a second leaf extending from the first edge region to the second edge region. The first leaf is the same distance as the second leaf from the central axis in the radial direction, and is adjacent to and overlaps the second leaf in the circumferential direction, when installed in a gas turbine. The first leaf is attached to the second leaf such that the first leaf can move relative to the second leaf in the circumferential direction when installed in a gas turbine.
