Latch beam deflection support
An engine nacelle is provided and includes an outer fixed structure (OFS) assembly disposed about an inner fixed structure (IFS) barrel and a latch beam, which is separate from the IFS barrel along an entire length thereof. The latch beam includes forward and trailing ends directly and indirectly supportively coupled to the OFS assembly, respectively.
1. An engine nacelle, comprising:
an inner fixed structure (IFS) comprising a barrel and an upper bifurcation at an upper portion of the barrel, the IFS having an absence of a bifurcation at a lower portion of the barrel;
an outer fixed structure (OFS) assembly disposed about the barrel of the IFS; and
a latch beam comprising forward and trailing ends directly and indirectly supportively coupled to the OFS assembly, respectively,
the latch beam being circumferentially located at and separated along an entire length thereof from the lower portion of the IFS barrel.
2. The engine nacelle according to claim 1 , further comprising a support member by which the trailing end of the latch beam is indirectly supportively coupled to the OFS assembly.
3. The engine nacelle according to claim 2 , wherein the support member is provided as first and second support members disposed on either side of the latch beam.
4. The engine nacelle according to claim 2 , wherein the support member has a C-channel cross-sectional shape.
5. The engine nacelle according to claim 2 , wherein the support member has at least one curved section disposed along a longitudinal length thereof.
6. The engine nacelle according to claim 2 , wherein the support member comprises:
multiple first branches at the first end, which are respectively coupled to the OFS assembly; and
multiple second branches at the second end, which are respectively coupled to the trailing end of the latch beam.
7. An engine nacelle, comprising:
an inner fixed structure (IFS) comprising a barrel and an upper bifurcation at an upper portion of the barrel, the IFS having an absence of a bifurcation at a lower portion of the barrel;
an outer fixed structure (OFS) assembly disposed about the barrel of the IFS;
a latch beam comprising a forward end coupled to the OFS assembly and a trailing end disposed aft of a direct connection between the forward end of the latch beam and the OFS assembly, the latch beam being circumferentially located at and separated along an entire length thereof from the lower portion of the IFS barrel; and
a support member comprising a first end coupled to the OFS assembly and a second end coupled to the trailing end of the latch beam.
8. The engine nacelle according to claim 7 , wherein the support member is provided as first and second support members disposed on either side of the latch beam.
9. The engine nacelle according to claim 7 , wherein the support member has a C-channel cross-sectional shape.
10. The engine nacelle according to claim 7 , wherein the support member has at least one curved section disposed along a longitudinal length thereof.
11. The engine nacelle according to claim 7 , wherein the support member comprises:
multiple first branches at the first end, which are respectively coupled to the OFS assembly; and
multiple second branches at the second end, which are respectively coupled to the trailing end of the latch beam.
