Abstract

A translating sleeve actuation system is provided. The translating sleeve actuation system may be configured with one or more screws coupled to one or more motors configured to drive the screws. The screws may be disposed in channels defined in the track beams. The translating sleeve actuation system may also comprise one or more shuttles configured to translate forward and aft along the screw in the track beam channels.

First claim

What is claimed is:

1. A Thrust reverser system, comprising:
a first track beam defining a first track beam channel;
a thrust reverser actuator integrated into the first track beam, the thrust reverser actuator comprising:
a first screw disposed in the first track beam channel and configured to rotate;
a motor mounted on a torque box having a first wall and a second wall with a cavity defined therebetween, the motor installed directly on the first wall and wherein the torque box is located between the motor and the translating sleeve and the motor configured to drive the first screw, the first screw and the motor having different rotational axes;
a first shuttle installed on the first screw, the first shuttle disposed in and configured to translate forward and aft in the first track beam channel; and
a translating sleeve coupled to the first shuttle and configured to translate along the first track beam.

2. The thrust reverser system of claim 1 , wherein the first shuttle includes a shuttle channel that is configured to receive the first screw.

3. The thrust reverser system of claim 1 , wherein the first shuttle is coupled to the translating sleeve with fasteners.

4. The thrust reverser system of claim 1 , wherein the first track beam is a hinge beam.

5. The thrust reverser system of claim 1 , further comprising a second shuttle coupled to the translating sleeve.

6. The thrust reverser system of claim 5 , further comprising a second track beam, the second track beam comprising a second track beam channel, wherein the second shuttle is disposed in and configured to translate forward and aft in the second track beam channel.

7. The thrust reverser system of claim 6 , wherein the second track beam is a latch beam.

8. A nacelle, comprising:
a track beam including a track beam channel;
a nut including a shuttle channel disposed in and configured to translate forward and aft in the track beam channel;
a translating sleeve operatively coupled to the nut and configured to translate along the track beam;
a screw rotatably installable in the shuttle channel and configured to drive the nut forward and aft in the track beam channel; and
a motor mounted on a torque box having a first wall and a second wall with a cavity defined therebetween, the motor installed directly on the first wall and wherein the torque box is located between the motor and the translating sleeve and the motor configured to drive the screw, the screw and the motor having different rotational axes.

9. The nacelle of claim 8 , further comprising a cascade having a continuous hoop structure.

10. The nacelle of claim 9 , wherein the continuous hoop structure defines a hoop load path.

11. The nacelle of claim 9 , further comprising a latch beam, wherein the track beam is a hinge beam.

12. The nacelle of claim 11 , wherein the cascade is supported by the latch beam and the hinge beam.

13. A thrust reverser system, comprising:
a first track beam defining a first track beam channel;
a first screw disposed in the first track beam channel and configured to rotate;
a motor mounted on a torque box having a first wall and a second wall with a cavity defined therebetween, the motor installed directly on the first wall and wherein the torque box is located between the motor and the translating sleeve and the motor configured to drive the first screw, the first screw and the motor having different rotational axes;
a first shuttle installed on the first screw, the first shuttle disposed in and configured to translate forward and aft in the first track beam channel; and
a translating sleeve fastened directly to the first shuttle.

14. The thrust reverser system of claim 13 , wherein the first shuttle includes a shuttle channel that is configured to receive the first screw.

15. The thrust reverser system of claim 13 , further comprising a second shuttle coupled to the translating sleeve and a second track beam, the second track beam comprising a second track beam channel, wherein the second shuttle is disposed in and configured to translate forward and aft in the second track beam channel.
