Abstract

A nacelle is disclosed. The nacelle may comprise, in various embodiments, a drag link fitting mounted to an Inner Fixed Structure (IFS) and pivotally attached to an end of a drag link, and a vent defining a passageway through the IFS to bring cooling air through the IFS. The drag link fitting may be aerodynamically associated with the vent such that the drag link fitting helps direct air into the vent.

First claim

I claim:

1. A nacelle comprising:
a drag link fitting mounted to an Inner Fixed Structure (IFS) and adapted to be pivotally attached to an end of a drag link; and
a vent defining a passageway through the IFS to bring cooling air through the IFS, the drag link fitting being aerodynamically associated with the vent such that the drag link fitting helps direct air into the vent;

wherein the drag link fitting comprises an outer portion and an inner portion, and the outer portion and the inner portion are joined,
wherein the drag link fitting comprises an air inlet which is generally forward of the drag link fitting and acts to scoop air from a fan air bypass duct and direct it to the vent.

2. The nacelle of claim 1 , wherein the drag link fitting further comprises the air inlet, wherein the air inlet is configured to aerodynamically cooperate with a vent in the IFS.

3. The nacelle of claim 1 , wherein the outer portion and the inner portion are joined to each other prior to the drag link fitting being joined to the IFS.

4. The nacelle of claim 1 , wherein the outer portion and the inner portion are joined together when they are each joined to the IFS.

5. The nacelle of claim 1 , wherein the vent descends through the IFS along a sloping trajectory.

6. The nacelle of claim 1 , wherein the vent descends through the IFS substantially orthogonally to a surface of the IFS.

7. The nacelle of claim 1 , wherein the drag link fitting further comprises a low profile air inlet.

8. A nacelle comprising:
a drag link fitting mounted to an Inner Fixed Structure (IFS) and adapted to be pivotally attached to an end of a drag link at a drag link coupling portion;
a vent defining a passageway through the IFS to bring cooling air through the IFS; and,
an air inlet integrated into the drag link fitting, the air inlet acting to scoop air flow from a bypass air duct and direct it into the vent.

9. The nacelle of claim 8 , wherein the drag link fitting further comprises an outer portion and an inner portion, and the outer portion and the inner portion are separately manufactured and are joined to each other prior to the drag link fitting being joined to the IFS.

10. The nacelle of claim 8 , wherein the drag link fitting further comprises an outer portion and an inner portion, and the outer portion and the inner portion are separately manufactured and are joined together when they are each joined to the IFS.

11. The nacelle of claim 8 wherein the drag link fitting and the vent are formed as an integral component before they are mounted to the IFS.
