Abstract
A seal assembly includes a body having two circumferential sides, a leading end, and a trailing end. At least one of the circumferential sides includes a first channel sidewall, a second channel sidewall, and a channel bottom wall that together define a seal channel for receiving a seal. The seal channel includes a slot that cooperates with a tab on the seal to facilitate securing the seal within the seal channel.
Claims5
A method of assembling a seal and a seal channel of a gas turbine engine component, comprising:
- providing the gas turbine engine component such that the gas turbine engine component includes the seal channel;
- wherein the seal channel includes an open top, a first sidewall, a second sidewall, a bottom wall, and a slot that extends through the bottom wall;
- compressing a resilient non-planar tab and inserting the resilient non-planar tab into the slot and through the bottom wall of the seal channel until the resilient non-planar tab decompresses and a portion of the tab is in contact with at least one of the first sidewall, the second sidewall, and the bottom wall such that the contact retains the seal within the seal channel and limits movement between the seal and the seal channel.
