Abstract

An assembly is provided for mounting a turbofan engine to a pylon. The turbofan engine includes a fan section and an engine core. The mounting assembly includes a fan case, a first mount and a second mount. The fan case is configured to house the fan section of the turbofan engine. The first mount is connected to the fan case, and configured to mount the fan case to the pylon. The second mount is connected to the fan case, and configured to mount the fan case to the pylon.

First claim

What is claimed is:

1. An assembly for mounting a turbofan engine to a pylon, the turbofan engine comprising a fan section and an engine core, the pylon comprising a first portion and a second portion axially aft of the first portion, the assembly comprising:
a fan case configured to house the fan section of the turbofan engine;
a first mount connected to the fan case, and configured to mount and structurally tie the fan case to the first portion of the pylon, and the first mount comprising a strut, the strut connected to and extending axially aft from the fan case, and the strut configured to transfer an axial thrust load between the fan case and the first portion of the pylon; and
a second mount connected to the fan case, and configured to mount and structurally tie the fan case to the second portion of the pylon independent of the first mount.

2. The assembly of claim 1 , wherein
the fan case extends along an axial centerline; and
the first mount is axially separated from the second mount.

3. The assembly of claim 1 , wherein
the fan case extends along an axial centerline between a first end and a second end; and
the first mount is connected to the fan case at the first end, and the second mount is connected to the fan case at the second end.

4. The assembly of claim 1 , wherein the second mount is configured to transfer one or more of a radial load, lateral load or a torsional load between the fan case and the pylon.

5. The assembly of claim 1 , wherein the strut is a first strut, the first mount further includes a second strut, the first strut and the second strut are arranged circumferentially around an axial centerline of the fan case, the second strut is connected to and extends axially aft from the fan case, and the second strut is configured to transfer an axial thrust load between the fan case and the first portion of the pylon.

6. The assembly of claim 1 , wherein
the second mount includes a mount beam and a plurality of links; and
the links are arranged circumferentially around an axial centerline of the fan case, and connect the mount beam to the fan case.

7. The assembly of claim 6 , wherein the strut is substantially circumferentially centered between the links and connected to the fan case.

8. The assembly of claim 1 , further comprising:
a core case configured to house the engine core of the turbofan engine; and
a third mount connected to the core case, and configured to mount the core case to the pylon.

9. The assembly of claim 8 , further comprising at least one vane arranged radially between the fan case and the core case.

10. The assembly of claim 8 , wherein
the third mount includes a mount beam and a plurality of links; and
the links are arranged circumferentially around an axial centerline of the core case, and connect the mount beam to the core case.

11. The assembly of claim 10 , wherein the third mount further includes at least one strut that is connected to and extends axially between the mount beam and the core case.

12. The assembly of claim 8 , further comprising a fourth mount connected to the core case and configured to mount the core case to the pylon.

13. An assembly for mounting a turbofan engine to a pylon, the turbofan engine comprising a fan section and an engine core, the pylon comprising a first portion and a second portion axially aft of the first portion, the assembly comprising:
a fan case configured to house the fan section of the turbofan engine, the fan case extending along an axial centerline;
a first mount connected to the fan case; and
a second mount connected to the fan case and axially separated from and aft of the first mount;
the first mount and the second mount each configured to mount the fan case to the pylon such that the first mount structurally ties the fan case to the first portion of the pylon and the second mount structurally ties the fan case to the second portion of the pylon; and
the first mount comprising a strut connected to and extending axially aft from the fan case, and the first mount configured to transfer an axial thrust load between the fan case and the first portion of the pylon.
