An exhaust nozzle for a gas turbine engine according to an exemplary aspect of the present invention includes: an outer cowl; a cowl interface ring attached to the outer cowl; an acoustic nozzle; an acoustic nozzle interface ring attached to the acoustic nozzle, the acoustic nozzle interface ring attachable to the cowl interface ring; and a removable nozzle section attachable to the acoustic nozzle interface ring and the cowl interface ring.

대표청구항 ▼

What is claimed is: 1. An exhaust nozzle for a gas turbine engine comprising: an outer cowl defined about an axis; a cowl interface ring attached to said outer cowl, said cowl interface ring defined about said axis; an acoustic nozzle defined about said axis to receive an engine exhaust; an acoustic nozzle interface ring attached to said acoustic nozzle, said acoustic nozzle interface ring defined about said axis, said acoustic nozzle interface ring attachable to said cowl interface ring; and a removable nozzle section defined about said axis, said removable nozzle section attachable to said acoustic nozzle interface ring and said cowl interface ring to receive said cowl interface ring at least partially between said nozzle interface ring and said removable nozzle section, said cowl interface ring and said acoustic nozzle interface ring includes a first row of apertures and a second row of apertures directed in a radial direction relative to said axis. 2. The exhaust nozzle as recited in claim 1, wherein said outer cowl and said acoustic nozzle form a section of a core cowl. 3. The exhaust nozzle as recited in claim 1, wherein said cowl interface ring is welded to said outer cowl. 4. The exhaust nozzle as recited in claim 1, wherein said acoustic nozzle interface ring is welded to said acoustic nozzle. 5. The exhaust nozzle as recited in claim 1, wherein said first row of apertures are staggered relative to said second row of apertures generally along said axis. 6. The exhaust nozzle as recited in claim 1, wherein said acoustic nozzle interface ring is attached to said cowl interface ring with a first multiple of fasteners through said first row of apertures, said first multiple of fasteners trapped by said removable nozzle section. 7. The exhaust nozzle as recited in claim 6, wherein said first multiple of fasteners are flush head fasteners. 8. The exhaust nozzle as recited in claim 6, wherein said first multiple of fasteners are rivets. 9. The exhaust nozzle as recited in claim 1, wherein said removable nozzle section is attachable to said acoustic nozzle interface ring and said cowl interface ring with a second multiple of fasteners through said second row of apertures, said second multiple of fasteners pass through said cowl interface ring, said nozzle interface ring and said removable nozzle section. 10. The exhaust nozzle as recited in claim 9, wherein said second multiple of fasteners are removable fasteners. 11. The exhaust nozzle as recited in claim 9, wherein said second multiple of fasteners are rivets. 12. The exhaust nozzle as recited in claim 1, wherein said cowl interface ring and said acoustic nozzle interface ring includes a first row of apertures and a second row of apertures, said acoustic nozzle interface ring attached to said cowl interface ring with a first multiple of fasteners through said first row of apertures, said first multiple of fasteners trapped by said removable nozzle section, said removable nozzle section attachable to said acoustic nozzle interface ring and said cowl interface ring with a second multiple of fasteners through said second row of apertures, said second multiple of fasteners pass through said cowl interface ring, said nozzle interface ring and said removable, nozzle section. 13. The exhaust nozzle as recited in claim 12, wherein said first multiple of fasteners are flush head fasteners and said second multiple of fasteners are removable fasteners. 14. The exhaust nozzle as recited in claim 12, wherein said first multiple of fasteners are flush head fasteners and said second multiple of fasteners are rivets. 15. The exhaust nozzle as recited in claim 1, wherein said acoustic nozzle interface ring is attached to said cowl interface ring with a first multiple of fasteners through said first row of apertures, said first multiple of fasteners do not pass through said removable nozzle section. 16. The exhaust nozzle as recited in claim 15, wherein said removable nozzle section extends downstream of said acoustic nozzle interface ring. 17. The exhaust nozzle as recited in claim 1, wherein said removable nozzle section extends downstream of said outer cowl interface ring.
