ACOUSTIC DAMPER ARRANGEMENT FOR A COMBUSTOR

摘要

Disclosed is an acoustic attenuator for a combustor including an inner liner constructed to be used in the first temperature during operation and an outer liner constructed to be operated in the second temperature which is lower than the first temperature during the operation. The acoustic attenuator comprises a plurality of flexibility sheets and at least one midair bodies fixed in one of the flexibility sheets and including an inner volume. The acoustic attenuator is fixed at the inner liner and the outer liner to communicate the inner volume of the midair bodies with a chamber formed by the inner liner. The flexibility sheets accommodates the contraction and expansion of the inner liner for the outer liner.
