Abstract

A fan exit guide vane with structurally capable acoustic treatment includes a leading edge and a trailing edge opposite chordwise from the leading edge; a radially inner attachment region opposite spanwise from a radially outer attachment region; a span dimension extending between the radially inner attachment region and the radially outer attachment region; a chord dimension extending between the leading edge and the trailing edge; a pressure side opposite a suction side of the fan exit guide vane; a structural feature and an acoustic receiver formed within the fan exit guide vane extending at least one of spanwise through the fan exit guide vane between the radially inner attachment region and the radially outer attachment region and/or chordwise between the leading edge and the trailing edge; and an acoustic panel inserted into the acoustic receiver. A gas turbine engine includes the fan exit guide vane with structurally capable acoustic treatment. A process forms the fan exit guide vane with structurally capable acoustic treatment.
