Abstract

A thrust reverser actuator system fitting and a v-blade may be coupled to a track beam. A portion of the load between a translating sleeve and a fan case may be transmitted through the track beam. The thrust reverser actuator system fitting may comprise an integral v-blade.

First claim

I claim:

1. A thrust reverser for an aircraft nacelle comprising:
a torque box having a front wall;
a hinge beam comprising:
an elongated body having a planer face;
a track disposed on the planer face;
a v-blade coupled to the hinge beam; and
a thrust reverser actuator system fitting disposed axially forward the front wall of the torque box on the planer face;

a translating sleeve configured to translate along the track; and
an actuator configured to translate the translating sleeve between a stowed position and a deployed position, wherein the actuator is coupled to the thrust reverser actuator system fitting.

2. The thrust reverser of claim 1 , wherein the v-blade is coupled to the thrust reverser actuator system fitting.

3. The thrust reverser of claim 2 , wherein the actuator, the thrust reverser actuator system fitting, the hinge beam, and the v-blade define a load path between the translating sleeve and a fan case.

4. The thrust reverser of claim 1 , wherein the v-blade is an integral v-blade.

5. The thrust reverser of claim 4 , wherein the actuator, the thrust reverser actuator system fitting, and the integral v-blade define a load path between the translating sleeve and a fan case.

6. The thrust reverser of claim 1 , wherein the hinge beam and the thrust reverser actuator system fitting comprise an integral component.

7. The thrust reverser of claim 6 , wherein the hinge beam and the thrust reverser actuator system fitting are manufactured together by a casting and machining process.

8. The thrust reverser of claim 1 , wherein the thrust reverser actuator system fitting is bolted to the hinge beam.

9. A thrust reverser for an aircraft nacelle comprising:
a torque box having a front wall and a torque box v-blade;
a hinge beam comprising:
an elongated body having a planer face;
a track disposed on the planer face; and
a thrust reverser actuator system fitting disposed axially forward the front wall of the torque box on the planer face, the thrust reverser actuator system fitting having a fitting v-blade;

a translating sleeve configured to translate along the track; and
an actuator configured to translate the translating sleeve between a stowed position and a deployed position, wherein the actuator is coupled to the thrust reverser actuator system fitting.
