Abstract

To provide an aircraft pylon capable of being mounted to a wing without exertion of preload while ensuring that redundancy is provided in the pylon. An aircraft pylon 50 includes: a pylon strut 11 for supporting an engine of an aircraft; a pin joint mechanism for connecting the pylon strut 11 to a main wing of the aircraft; a link member 15 disposed between the pylon strut 11 and the main wing of the aircraft, wherein the link member 15 includes a collection of plural independent link elements.

First claim

What is claimed is:

1. An aircraft pylon comprising:
a pylon strut for supporting an engine of an aircraft;
a pin joint mechanism for connecting the pylon strut to a main wing of the aircraft; and
a link member disposed between the pylon strut and the main wing of the aircraft, wherein the link member comprises a collection of plural independent link elements,
wherein the plural independent link elements are separately attached to the pylon strut, and
the plural independent link elements are attached to each other and partly butted against each other.

2. The aircraft pylon according to claim 1 , wherein the plural independent link elements are fastened together.

3. The aircraft pylon according to claim 1 , wherein the link member comprises the plural independent link elements each being pin jointed to the pylon strut and the main wing.

4. The aircraft pylon according to claim 1 , wherein, in connecting the pin joint mechanism and the link member to the main wing, respectively, the pin joint mechanism and the link member are connected to a common fitting provided on the main wing.

5. The aircraft pylon according to claim 1 , wherein the link member is provided above the pin joint mechanism.

6. The aircraft pylon according to claim 1 , wherein the position of the pin joint mechanism is a reference position to which the pylon strut is mounted.

7. The aircraft pylon according to claim 1 , wherein
the plural independent link elements are each attached to the pylon strut with a separate fastener, and
the plural independent link elements are attached adjacent to each other with another fastener.

8. The aircraft pylon according to claim 1 , wherein the plural independent link elements are channel steels.

9. The aircraft pylon according to claim 1 , wherein the link member includes a connecting piece provided at an end of each of the plural independent link elements.

10. The aircraft pylon according to claim 9 , wherein the connecting piece defines a plurality of recesses.

11. The aircraft pylon according to claim 10 , wherein the pylon strut further includes a plurality of projections at an end thereof that are arranged in the plurality of recesses, respectively, and are each pin-jointed to a corresponding one of the plural independent link elements by its associated separate fastener.

12. An aircraft comprising a pylon, wherein the pylon comprises:
a pylon strut for supporting an engine;
a pin joint mechanism for connecting the pylon strut to a main wing of the aircraft; and
a link member disposed between the pylon strut and the main wing of the aircraft, wherein the link member comprises a collection of plural independent link elements,
wherein the plural independent link elements are separately attached to the pylon strut, and
the plural independent link elements are attached to each other and partly butted against each other.
