Ribbed structural swirl recovery vane with acoustic capability

A gas turbine engine with a swirl recovery vane with structurally capable acoustic treatment comprising:

• a propulsor rotor located within an open environment;
• and
• an array of swirl recovery vanes supported downstream from the propulsor rotor, the array of swirl recovery vanes attached to a nacelle flow surface;
• each swirl recovery vane of the array of swirl recovery vanes comprising:
• a leading edge and a trailing edge opposite chordwise from the leading edge;
• an attachment region opposite spanwise from a tip region;
• a span dimension extending between the attachment region and the tip region;
• a chord dimension extending between the leading edge and the trailing edge;
• a pressure side opposite a suction side of the swirl recovery vane;
• a structural feature formed within the swirl recovery vane extending at least one of spanwise through the swirl recovery vane between the attachment region and the tip region and/or chordwise between the leading edge and the trailing edge;
• an acoustic receiver formed within the structural feature extending at least one of spanwise through the swirl recovery vane between the attachment region and the tip region or chordwise between the leading edge and the trailing edge;
• an acoustic receiver shape selected from the group consisting of oval, circle, semicircle, rhombus, diamond, pentagon, hexagon, octagon, nonagon, decagon;
• and
• an acoustic panel inserted into the acoustic receiver.

A process for gas turbine engine with a swirl recovery vane with a structurally capable acoustic treatment comprising:

• locating a propulsor rotor within an open environment;
• supporting an array of swirl recovery vanes downstream from the propulsor rotor;
• attaching the array of swirl recovery vanes to a nacelle flow surface by;
• coupling an attachment region of a swirl recovery vane of the array of swirl recovery vanes in operative communication with the nacelle flow surface;
• forming a structural feature within the swirl recovery vanes extending at least one of spanwise through the swirl recovery vane between the attachment region and a tip region of the swirl recovery vane and/or chordwise from a leading edge to a trailing edge;
• forming an acoustic receiver within the swirl recovery vane extending at least one of spanwise from the swirl recovery vane between the attachment region and the tip region or chordwise from the leading edge to the trailing edge;
• forming an acoustic receiver shape selected from the group consisting of oval, circle, semicircle, rhombus, diamond, pentagon, hexagon, octagon, nonagon, decagon;
• and
• inserting an acoustic panel into the acoustic receiver.
