Abstract

A thrust reverser may include a frame, a track disposed on the frame, a carrier operatively coupled to the track, a first reverser door operatively coupled to the carrier, the first reverser door is movable relative to the frame, wherein the first reverser door is configured to move to a first position in response to the carrier moving with respect to the track in a first direction, and move to a second position in response to the carrier moving with respect to the track in a second direction, and a deployable fairing pivotally coupled to the frame, the deployable fairing operatively coupled to the carrier, wherein the deployable fairing is configured to move away from a central axis of the thrust reverser to provide clearance for the reverser door to rotate into a deployed position.

First claim

What is claimed is:

1. An actuation arrangement for a thrust reverser, comprising:
a carrier configured to translate along a track disposed on a frame of the thrust reverser, wherein the carrier is configured to rotate a first reverser door about a second axis between a closed position and an open position in response to the carrier translating along the track; and
a deployable fairing pivotally coupled to the frame, the deployable fairing operatively coupled to the carrier, wherein the deployable fairing is configured to rotate about a first axis away from a central axis of the thrust reverser to provide clearance for the first reverser door to rotate into a deployed position;
wherein the first axis is substantially orthogonal to the second axis.

2. The actuation arrangement of claim 1 , further comprising a first link configured to be pivotally coupled to the carrier, wherein the carrier is configured to move the first reverser door between the closed position and the open position via the first link.

3. The actuation arrangement of claim 2 , further comprising a linear actuator configured to be coupled to the frame, wherein the carrier is driven by the linear actuator.

4. The actuation arrangement of claim 3 , wherein the carrier is configured to react loads that are parallel to a line-of-action of the linear actuator from the first link into the linear actuator and configured to react loads that are non-parallel to the line-of-action of the linear actuator from the first link into the track.

5. The actuation arrangement of claim 2 , further comprising a second link configured to be pivotally coupled to the carrier, wherein the carrier is configured to move a second reverser door between a closed position and an open position via the second link.

6. The actuation arrangement of claim 1 , wherein the carrier comprises a track lug and the track comprises a groove configured to receive the track lug.

7. The actuation arrangement of claim 1 , wherein the actuation arrangement further comprises:
a bell crank pivotally coupled to the frame;
a first link pivotally coupled to the carrier; and
a second link pivotally coupled to the deployable fairing.

8. The actuation arrangement of claim 7 , wherein the bell crank moves from a first position to a second position in response to the carrier translating along the track.

9. The actuation arrangement of claim 8 , wherein the deployable fairing moves from a stowed position to a deployed position in response to the bell crank moving from the first position to the second position.

10. A thrust reverser, comprising:
a frame;
a track disposed on the frame;
a carrier operatively coupled to the track;
a first reverser door operatively coupled to the carrier, the first reverser door is movable relative to the frame, wherein the first reverser door is configured to move to a first position in response to the carrier moving with respect to the track in a first direction, and move to a second position in response to the carrier moving with respect to the track in a second direction;
a second reverser door operatively coupled to the carrier; and
a deployable fairing pivotally coupled to the frame and disposed between the first reverser door and the second reverser door, wherein the deployable fairing is disposed outward from the frame with respect to the central axis of the thrust reverser, the deployable fairing is flush with the first reverser door and the second reverser door in response to the thrust reverser being in a stowed position, the deployable fairing operatively coupled to the carrier, and the deployable fairing is configured to move away from a central axis of the thrust reverser to provide clearance for the first reverser door to rotate into a deployed position.

11. The thrust reverser of claim 10 , wherein the first reverser door is configured to rotate to the first position in response to the carrier moving linearly with respect to the track in the first direction.

12. The thrust reverser of claim 10 , further comprising a first link, wherein the carrier is coupled to the first reverser door via the first link.

13. The thrust reverser of claim 12 , wherein a first end of the first link is pivotally coupled to the first reverser door and a second end of the first link is pivotally coupled to the carrier.

14. The thrust reverser of claim 10 , further comprising a linear actuator coupled to the frame, wherein the linear actuator is configured to move the carrier with respect to the track.

15. The thrust reverser of claim 10 , further comprising a second link, wherein the carrier is coupled to the second reverser door via the second link.

16. The thrust reverser of claim 15 , wherein a first end of the second link is pivotally coupled to the second reverser door and a second end of the second link is pivotally coupled to the carrier.
