Abstract
An acoustically dampened gas turbine engine () having a gas turbine engine combustor () with an acoustic damping resonator system () is disclosed. The acoustic damping resonator system () may be formed from one or more resonators () formed from a resonator housing () positioned within the gas turbine engine combustor () at an outer housing () forming a combustor basket () and extending circumferentially within the combustor (). In at least one embodiment, the resonator housing () may include resonator chambers () that may be welded in place within resonator chamber () receivers () but easily replaceable without exposing the resonator housing () to damage. In another embodiment, an inner surface () of the resonator chamber () may be offset radially outward from an inner surface () of the resonator housing (), thereby creating a flow-path discontinuity and reducing heating of the resonator chamber (). The acoustic damping resonator system () may mitigate dynamics thereby increasing an engine operating envelope and decreasing emissions.
