Abstract
A swirl recovery vane with acoustic treatment including 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; an acoustic panel receiver 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 or chordwise between the leading edge and the trailing edge; and an acoustic panel inserted into the acoustic panel receiver.
Claims12
A gas turbine engine with a swirl recovery vane with acoustic treatment comprising:
- a propulsor rotor located within an open environment;
- and
- an array of swirl recovery vanes downstream from the propulsor rotor, the array of swirl recovery vanes attached to a nacelle flow surface;
- wherein each swirl recovery vane of the array of swirl recovery vanes comprises:
- 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;
- an acoustic panel receiver 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 or chordwise between the leading edge and the trailing edge;
- and
- an acoustic panel inserted into the acoustic panel receiver wherein the acoustic panel is configured slidable into the acoustic panel receiver from at least one of the attachment region, the tip region, the leading edge and the trailing edge, the acoustic panel being trapped by geometry of the acoustic panel receiver.
A process for creating a swirl recovery vane with acoustic treatment comprising:
- supporting an array of swirl recovery vanes downstream from a location associated with a propulsor rotor in an open environment;
- 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 an acoustic panel receiver within the swirl recovery vane extending at least one of spanwise through the swirl recovery vane between the attachment region and the tip region or chordwise between a leading edge and a trailing edge of the swirl recovery vane;
- wherein the acoustic panel is configured slidable into the acoustic panel receiver from at least one of the attachment region, the tip region, the leading edge and the trailing edge, the acoustic panel being trapped by geometry of the acoustic panel receiver, slidably inserting the acoustic panel into the acoustic panel receiver from at least one of the attachment region, the tip region, the leading edge and the trailing edge;
- trapping the acoustic panel by a geometry of the acoustic panel receiver;
- and
- inserting an acoustic panel into the acoustic panel receiver.
