Abstract

A cascade support structure for a cascade type thrust reverser system is provided. One or more cascades may comprise one or more flanges. One or more actuators may also comprise one or more flanges. The cascades may be coupled to and/or supported by the actuators via the flanges. The cascades and/or actuators may also be configured to couple to one or more track beams via the ore or more flanges.

First claim

What is claimed is:

1. A thrust reverser system, comprising:
a first cascade including a first flange;
a second cascade including a second flange; and
a first actuator comprising a body, wherein the body comprises a third flange and a fourth flange,
wherein the first cascade is operatively coupled to the first actuator by the first flange and the third flange,
wherein the second cascade is operatively coupled to the first actuator by the second flange and the fourth flange, and
wherein the first cascade, the first flange the third flange, the actuator, the fourth flange, the second flange, and the second cascade form a portion of a hoop load path.

2. The thrust reverser system of claim 1 , wherein the first cascade comprises a fifth flange.

3. The thrust reverser system of claim 2 , further comprising a second actuator comprising a body including a sixth flange and a seventh flange, wherein the first cascade is operatively coupled to the second actuator by the fifth flange and the sixth flange.

4. The thrust reverser system of claim 3 , further comprising a track beam comprising an eighth flange.

5. The thrust reverser system of claim 4 , Wherein the second actuator is operatively coupled to the track beam by the seventh flange and the eighth flange.

6. The thrust reverser system of claim 5 , wherein the first cascade, the second cascade, and the second actuator form an assembly that is operatively coupled to the track beam.

7. The thrust reverser system of claim 6 , wherein the assembly defines the hoop load path.

8. the thrust reverser system of claim 1 , wherein the assembly is housed within a translating sleeve of the thrust reverser system.

9. A propulsion system, comprising:
a translating sleeve;
a plurality of cascades, each cascade of the plurality of cascades comprising a first flange and a second flange;
a plurality of actuators, each actuator of the plurality of actuators comprising a body, wherein the body comprises a third flange and a fourth flange;
a first track beam comprising a fifth flange; and
a second track beam comprising a sixth flange,
wherein a first cascade of the plurality of cascades is coupled to a first actuator of the plurality of actuators via the first flange and the third flange, and
wherein the first cascade is coupled to the first track beam via the second flange and the fifth flange, and
wherein the plurality of cascades and the plurality of actuators form a portion of a hoop load path.

10. The propulsion system of claim 9 , wherein the plurality of cascades and the plurality of actuators are coupled together to form a cascade assembly.

11. The propulsion system of claim 10 , wherein the translating sleeve comprises an inner sleeve and an outer sleeve, and wherein the cascade assembly is housed between the inner sleeve and the outer sleeve when the translating sleeve is in the stowed position.

12. The propulsion system of claim 9 , wherein the plurality of cascades and the plurality of actuators are coupled together to form a hoop load path between the first track beam and the second track beam.

13. The propulsion system of claim 9 , wherein a second cascade of the plurality of cascades is coupled to the first actuator via the first flange of the second cascade and the forth flange of the first actuator.

14. The propulsion system of claim 13 , wherein the second cascade is coupled to a second actuator of the plurality of actuators via the second flange of the second cascade and the third flange of the second actuator.

15. The propulsion system of claim 9 , wherein the plurality of cascades comprises the first cascade, a second cascade and a third cascade.
