Abstract
A gas turbine engine includes a rotor that has a seal surface and a shaft that is rotatable about an engine central axis. The shaft has an annular seal channel that opens to the seal surface. An annular seal is insertable into the annular seal channel for sealing against the seal surface. The annular seal is comprised of first and second rings that each have a split joint, a slot radially adjacent the split joint, and a tab that projects into the slot of the other of the first or second rings such that the first and second rings are circumferentially interlocked.

A gas turbine engine comprising:
- a rotor having a seal surface;
- a shaft rotatable about an engine central axis, the shaft having an annular seal channel that opens to the seal surface;
- and
- an annular seal that is insertable into the annular seal channel for sealing against the seal surface, the annular seal being comprised of first and second rings, each of the first and second rings having a split joint, a slot radially adjacent the split joint, and a tab that projects into the slot of the other of the first or second rings such that the first and second rings are circumferentially interlocked.
An annular seal for a gas turbine engine, comprising:
- first and second rings, each of the first and second rings having at least one split joint, at least one slot radially adjacent the at least one split joint, and at least one tab that projects into the at least one slot of the other of the first or second ring such that the first and second rings are circumferentially interlocked.
A method of assembling a seal into a gas turbine engine, the method comprising:
- providing an annular seal that has first and second rings, each of the first and second rings has a split joint, a slot radially adjacent the split joint, and a tab;
- arranging the first ring next to the second ring such that the tab on each of the first and second rings projects into the slot of the other of the first and second rings to circumferentially interlock the first and second rings together;
- and
- arranging the annular seal into the annular seal channel.
