<p>The present invention relates to a resonator (100) with an adaptable resonator frequency (f) for absorbing sound generated by a gas stream of a gas turbine (110). The resonator (100) comprises a neck section (102), a chamber (101) and a deformable element (103) being deformable under influence of a change of a gas turbine temperature of the gas stream. The shape of the deformable element (103) is predetermined with respect to a respective gas turbine temperature. The neck section (102) and the chamber (101) form a volume of the resonator (100). The neck section (102) forms a passage coupling the volume with the gas turbine (110). The deformable element (103) is thermally coupled to the gas turbine (110) in such a way that the shape of the deformable element (103) depends on the respective gas turbine temperature. The deformable element (103) forms a spiral (300) and is installed to the neck section (102) in such a way that an effective diameter (D2, eff) of the neck section (102) depends on the gas turbine temperature. The shape of the spiral (300) depends on the respective gas turbine temperature for selectively adapting the effective diameter (D2, eff) of the neck section.</p> |
