GAS TURBINE COMBUSTOR WITH MOUNTING FOR HELMHOLTZ RESONATORS.

摘要

A combustor liner may include an annular inner liner (82,92) and an annular outer liner (84, 94) with a plurality of air holes (83,85) thereon. The outer liner may be positioned circumferentially around the inner liner such that an annular cooling space (74,75) is defined between the inner and the outer liner. The combustor liner may also include at least one resonator (40) coupled to the outer liner such that a base (40a) of the resonator is separated from the outer liner to form a gap (62) with an external surface of the outer liner. The combustor liner may also include a throat (44) extending from the base of the resonator penetrating the inner liner and the outer liner. The combustor liner may further include a grommet assembly (76, 78) that allows for relative thermal expansion between the inner liner and the outer liner proximate the throat.
