Abstract

A thrust reverser for a nacelle may comprise a composite track beam and a composite lug. The composite lug may be inserted through a through-hole in the composite track beam. Continuous fibers in the composite lug may provide strength in the in-plane direction.

First claim

We claim:

1. A track beam for an aircraft nacelle comprising:
a first longitudinal panel;
a second longitudinal panel integrally affixed to the first longitudinal panel along a longitudinal edge, the second longitudinal panel comprising a through-hole; and
a lug coupled to the second longitudinal panel, the lug comprising:
a portion of a first flange located on a first side of the second longitudinal panel, the first flange extending through the through-hole;
a support located on a second side of the second longitudinal panel; and
a continuous fiber located partially within the first flange and partially within the support, wherein
the lug is configured to fuse to the second longitudinal panel.

2. The track beam of claim 1 , wherein the lug comprises a composite material.

3. The track beam of claim 1 , wherein the lug comprises a thermoplastic material.

4. The track beam of claim 1 , wherein the second longitudinal panel and the lug are configured to form a unitary component.

5. The track beam of claim 1 , wherein the lug comprises a second flange on the first side of the second longitudinal panel.

6. The track beam of claim 5 , further comprising a second continuous fiber located partially within the second flange and partially within the support.

7. The track beam of claim 1 , wherein the lug comprises at least one of a U-shape or a Pi-shape.

8. The track beam of claim 1 , wherein the second longitudinal panel and the lug are co-cured.

9. The track beam of claim 1 , wherein the first flange comprises an attachment feature.
