Abstract (en)
[origin: EP1596130A1] The damper includes at least one resonator (3). At least part of a wall (6) of the resonator can change position to set the resonator volume. The resonator is a Helmholtz resonator. The movable part of the wall is preferably provided with a thread. An independent claim is included for a gas turbine.
