Abstract
A gas turbine engine includes a rotatable component, and an engine casing disposed about the rotatable component. The engine casing includes a casing treatment having a plurality of grooves and a plurality of acoustic chambers. Each of the plurality of grooves is defined in the engine casing with a groove depth, and each of the plurality of acoustic chambers has an acoustic chamber depth based on the groove depth. Two of the plurality of grooves are associated with one of the plurality of acoustic chambers, one of the plurality of grooves is associated with a second one of the plurality of acoustic chambers, and the one of the plurality of acoustic chambers has an acoustic configuration that is different than the second one of the plurality of acoustic chambers.
