A seal has first and second spring elements each having first and second surfaces along a bellows cross-section and extending between first and second edges. A spreader is secured to an endplate between the first edges of the first and second elements to capture first edge portions of the first and second elements.

Seal

It is disclosed a seal assembly () which comprises a layered structure. It consists of a first layer () of a base material, a second layer () of thermal insulating material on top of the base material and a third layer () of base material or an oxide resistant material on top of the second layer () of thermal insulation. The inventive seal assembly () described herein can be arranged between combustor liner segments ().

Seal assembly

A metallic seal includes a cold formed substrate layer and one or more additional layers. At least one of the layers offers improved resistance to high temperature stress relaxation.

High temperature metallic seal

A seal has a metallic body having a convoluted cross-section extending between first and second ends and a first generally interior surface extending between the first and second ends and a second generally exterior surface extending between the first and second ends. An adhesive is located in one or more locations on at least one of the surfaces, the adhesive holding the body in a longitudinally contracted condition. There are related methods of manufacture. In related methods of use, the adhesive is caused to release, allowing the seal to expand toward the relaxed condition.
