A seal assembly () for a gas turbine engine for controlling air flow between a diffuser () and rotor disks comprising first and second annular flange ends () and an annular seal mid-section () between and operatively connected to the flange ends (). The first and second annular flange ends () abut respective outer frame members () of the diffuser, whereby a fluid flow path is formed between the seal assembly () and the rotor disks (). The first and second end flanges () are composed of a material having a coefficient of thermal expansion that is substantially the same as a coefficient of thermal expansion of the material of the outer frame members (). In addition, the material of the seal mid-section () has a coefficient of thermal expansion that is different than that of the materials of the annular flange ends () and outer frame members ().

Seal assembly for controlling fluid flow

A gas turbine includes an annular combustion chamber and an outer wall of an annular combustion chamber. A straining ring is arranged on the outer wall of the annular combustion chamber and enables oscillations of the outer wall to be damped via friction. The effects of combustion oscillations produced by damaging vibrations of the annular combustion chamber are thus reduced. A method is further for damping an oscillation of an outer wall of an annular combustion chamber.
