Abstract

An assembly is provided for an aircraft. This aircraft assembly includes an aircraft propulsion system and a pylon configured to mount the aircraft propulsion system to an airframe member. The pylon includes a first pylon structure and a second pylon structure. The first pylon structure is configured to mount to the airframe member. The second pylon structure is mounted to the aircraft propulsion system. The second pylon structure is configured to disconnect from the first pylon structure while mounted to the airframe member.

First claim

We claim:

1. An assembly for an aircraft, comprising:
an airframe member comprising an aircraft wing;
an aircraft propulsion system; and
a pylon configured to mount the aircraft propulsion system to the airframe member, the pylon including a first pylon structure and a second pylon structure;
the first pylon structure configured to mount to the airframe member;
the second pylon structure mounted to the aircraft propulsion system, and configured to disconnect from the first pylon structure while mounted to the airframe member;
the aircraft wing comprising a first wing structure and a second wing structure configured to disconnect from the first wing structure when the second pylon structure is disconnected from the first pylon structure; and
the second wing structure forming a portion of a trailing edge of the aircraft wing and is mounted to the second pylon structure.

2. The assembly of claim 1 , wherein the second pylon structure is configured to disconnect from the first pylon structure by moving along a generally horizontal axis.

3. The assembly of claim 2 , wherein the horizontal axis is substantially parallel to a rotational axis of the aircraft propulsion system.

4. The assembly of claim 1 , further comprising:
a fluid line including a first segment and a second segment removably coupled to the first segment at an interface between the first pylon structure and the second pylon structure;
wherein the first segment is arranged with the first pylon structure and the second segment is arranged with the second pylon structure.

5. The assembly of claim 1 , further comprising:
a non-fluid line including a first segment and a second segment removably coupled to the first segment at an interface between the first pylon structure and the second pylon structure;
wherein the first segment is arranged with the first pylon structure and the second segment is arranged with the second pylon structure.

6. The assembly of claim 1 , wherein the pylon is further configured to mount the aircraft propulsion system at least substantially vertically above the aircraft wing.

7. The assembly of claim 1 , wherein the pylon is further configured to mount the aircraft propulsion system at least substantially aft of the aircraft wing.

8. The assembly of claim 1 , the first pylon structure is connected to the second pylon structure at a butt joint.

9. The assembly of claim 1 , wherein the pylon is further configured to mount the aircraft propulsion system at least substantially vertically above the aircraft wing.

10. The assembly of claim 1 , wherein the pylon is further configured to mount the aircraft propulsion system at least substantially aft of the aircraft wing.
