Abstract
A structural guide vane with acoustic panel retention including an acoustic panel inserted into an acoustic panel receiver; a retention tab formed near a trailing edge of the acoustic panel; a leading edge extension formed near a leading edge of the acoustic panel; a tab receiver formed in the structural guide vane near a trailing edge of the structural guide vane; and a leading edge cap secured over the leading edge extension and leading edge of the structural guide vane to encapsulate and secure the acoustic panel into the acoustic receiver.
Claims20
A structural guide vane with acoustic panel retention comprising:
- 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 structural guide vane;
- an acoustic panel receiver formed within the structural guide vane extendable at least one of spanwise through the structural guide vane between the radially inner attachment region and the radially outer attachment region or chordwise between the leading edge and the trailing edge;
- and
- an acoustic panel inserted into the acoustic panel receiver;
- a retention tab formed near a trailing edge of the acoustic panel;
- a leading edge extension formed near a leading edge of the acoustic panel;
- a tab receiver formed in the structural guide vane near the trailing edge of the structural guide vane;
- and
- a leading edge cap secured over the leading edge extension and the leading edge of the structural guide vane to encapsulate and secure the acoustic panel into the acoustic receiver.
