## Abstract

An aircraft is described and includes a fuselage; wings attached to the fuselage; and a torque box within the fuselage, the torque box including a side panel, the side panel comprising a composite laminate material including a plurality of stiffening beads integrated therewith.

## Claims

### Claim 1

A torque box for containing damage subsequent to a hydraulic ram (hydram) event within the torque box, the torque box disposed within a fuselage of an aircraft and including first and second side panels disposed on opposite sides of the torque box, wherein each of the side panels comprises a composite laminate material including a plurality of stiffening beads integrated therewith and wherein end portions of the stiffening beads comprise ramp portions extending from top surfaces of the stiffening beads to a flat portion of the side panels.

### Claim 2 (depends on 1)

The torque box of claim 1, wherein the plurality of stiffening beads extend parallel to one another.

### Claim 3 (depends on 1)

The torque box of claim 1, wherein ends of the stiffening beads are square.

### Claim 4 (depends on 1)

The torque box of claim 1, wherein an angle between a surface of the flat portion of the side panel and each of the ramp portions is less than approximately 10 degrees.

### Claim 5 (depends on 1)

The torque box of claim 1, wherein the stiffening beads have at least one thickness dimension T1, at least one height dimension H1, and at least one width dimension W1, and the ramp portions have at least one length dimension L1, and wherein the dimensions T1, H1, W1, and L1, are related to one another by at least one mathematical equation.

### Claim 6 (depends on 1)

The torque box of claim 1, wherein the composite laminate material comprises a carbon fiber material.
