Abstract
A manufacturing process is provided during which a thrust reverser cascade is formed for an aircraft propulsion system. During the formation of the thrust reverser cascade, a first panel of material is stamped into a first corrugated body. A second panel of material is stamped into a second corrugated body. The first corrugated body is bonded to the second corrugated body.

A manufacturing process, comprising:
- forming a thrust reverser cascade of an aircraft propulsion system, the forming of the thrust reverser cascade comprising
- forming a first panel of material into a first corrugated body, wherein the first corrugated body comprises a first corrugated body first section and a first corrugated body second section that meets and is connected to the first corrugated body first section at a first corner;
- forming a second panel of material into a second corrugated body, wherein the second corrugated body comprises a second corrugated body first section and a second corrugated body second section that meets and is connected to the second corrugated body first section at a second corner;
- and
- bonding the first corrugated body to the second corrugated body, wherein the first corner is abutted against the second corner;
- wherein the thrust reverser cascade includes a first rail, a second rail and a plurality of vanes connected to and extending between the first rail and the second rail;
- wherein the first corrugated body comprises a first corrugation;
- wherein a first section of the first corrugation forms a first of the plurality of vanes, and a second section of the first corrugation forms a first portion of the first rail;
- wherein the second corrugated body comprises a second corrugation;
- and
- wherein a first section of the second corrugation forms a second of the plurality of vanes that is spaced from the first of the plurality of vanes by an air channel, and a second section of the second corrugation forms a second portion of the first rail that is in line with the first portion of the first rail.
