Apparatus including heat exchanger and sound attenuator for gas turbine engine

Abstract:

An apparatus for attenuating sound waves in a gas turbine engine includes a surface at least partially defining a pathway for airflow and a plurality of fins extending from the surface. The plurality of fins are configured to dissipate heat into the airflow. Each fin of the plurality of fins includes a fin surface. The fin surface is configured to direct the sound waves between the plurality of fins such that the plurality of fins attenuate the sound waves. The plurality of fins are arranged such that spacing between adjacent fins of the plurality of fins facilitates sound attenuation.
