Acoustic damper assembly for a gas turbine engine

Abstract

A gas turbine engine including a turbomachine. The turbomachine including a compressor section, a combustion section, and a turbine section arranged in serial flow order and together defining a working gas flowpath. The gas turbine engine further including an acoustic damper assembly defining an air flow path in fluid communication with the working gas flow path. The acoustic damper assembly including a seal positioned within the air flowpath; and an acoustic damper in flow communication with the air flowpath, the acoustic damper defining an acoustic damper cavity having a resonance frequency to mitigate acoustic resonance around the seal during operation of the gas turbine engine.
