Patent 11123916 - Forming a thrust reverser cascade using corrugated bodies > Claims

  • 1. A manufacturing process, comprising: forming a thrust reverser cascade for an aircraft propulsion system, the forming of the thrust reverser cascade comprisingstamping 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;stamping 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; andbonding the first corrugated body to the second corrugated body, the bonding of the first corrugated body to the second corrugated body comprises bonding the first corner to 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; andwherein 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 adjacent, connected to and parallel with the first portion of the first rail.
    • 2. The manufacturing process of claim 1, wherein the first panel of material comprises polymer material.
    • 3. The manufacturing process of claim 1, wherein the first panel of material is a fiber-reinforced thermoplastic panel of material.
    • 4. The manufacturing process of claim 1, wherein the first corner is configured with a first chamfered edge.
      • 5. The manufacturing process of claim 4, wherein the second corner is configured with a second chamfered edge; andthe second chamfered edge is bonded to the first chamfered edge.
    • 6. The manufacturing process of claim 1, wherein the first corrugated body includes a radiused interior corner positioned opposite the first corner.
    • 7. The manufacturing process of claim 1, wherein the first corrugated body further comprises a second corrugation; anda section of the second corrugation forms a first portion of the second rail.
    • 8. The manufacturing process of claim 1, wherein the forming of the thrust reverser cascade further comprises bonding a third panel of material to the first corrugated body and the second corrugated body; andthe third panel of material at least partially forms an exterior sidewall of the thrust reverser cascade.
    • 9. The manufacturing process of claim 1, wherein the first panel of material is configured with a continuous length of fiber reinforcement that extends end-to-end through the first panel of material.
  • 10. A manufacturing process, comprising: forming a thrust reverser cascade for an aircraft propulsion system, the forming of the thrust reverser cascade comprisingforming a first panel of material into a first corrugated body with a plurality of first corrugations, wherein each of the first corrugations comprises a first corrugation first section and a first corrugation second section that meets and is connected to the first corrugation first section at a first corner;forming a second panel of material into a second corrugated body with a plurality of second corrugations, wherein each of the second corrugations comprises a second corrugation first section and a second corrugation second section that meets and is connected to the second corrugation first section at a second corner; andbonding the first corner of each of the plurality of first corrugations to the second corner of a respective one of the plurality of second corrugations;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 a first section of a first of the first corrugations forms a first of the plurality of vanes, and a second section of the first of the first corrugations forms a first portion of the first rail; andwherein a first section of a first of the second corrugations 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 first of the second corrugations forms a second portion of the first rail that is adjacent, connected to and parallel with the first portion of the first rail.
    • 11. The manufacturing process of claim 10, wherein the thrust reverser cascade comprises fiber reinforcement within a polymer matrix.
    • 12. The manufacturing process of claim 10, wherein the forming of the thrust reverser cascade further comprises bonding a flat panel of material to each of the first corrugated body and the second corrugated body; andthe flat panel of material at least partially forms an exterior sidewall of the thrust reverser cascade.
    • 13. The manufacturing process of claim 10, wherein the first panel of material is configured with a continuous length of fiber that extends at least substantially along an entire length of the first panel of material.
    • 14. The manufacturing process of claim 10, wherein the first panel of material is a fiber-reinforced thermoplastic panel of material.
