Convergent divergent nozzle with edge cooled divergent seals

A divergent seal for a convergent/divergent nozzle system comprising:

• a first skin;
• and
• a second skin having a multiple of intakes arranged downstream of a hinge axis, said second skin attached to said first skin to define a longitudinal cooling airflow channel therebetween, said longitudinal cooling airflow channel in communication with said multiple of intakes and a multiple of edge channels formed between said first skin and said second skin along at least one longitudinal side of said divergent seal, said multiple of edge channels transverse to said longitudinal cooling airflow channel, wherein said first skin is a cold sheet and said second skin is a hot sheet, said multiple of intakes through said hot sheet.

A divergent seal for a convergent/divergent nozzle system comprising:

• a divergent seal body having a multiple of intakes arranged downstream of a hinge axis, said multiple of intakes communicate with a longitudinal cooling airflow channel within said divergent seal body, said longitudinal cooling airflow channel in communication with a multiple of edge channels along a longitudinal side of said divergent seal body;
• and
• a joint structure attached to said divergent seal body, said joint structure defines said hinge axis.

A divergent seal for a convergent/divergent nozzle system comprising:

• a divergent seal body having a multiple of intakes arranged downstream of a hinge axis, said multiple of intakes communicate with a longitudinal cooling airflow channel within said divergent seal body, said longitudinal cooling airflow channel in communication with a multiple of edge channels along a longitudinal side of said divergent seal body, wherein said multiple of intakes are located adjacent a forward end section of said divergent seal body, said forward end section includes a radiused surface and an aft end section of said divergent seal body defines a chevron shape.

A divergent seal for a convergent/divergent nozzle system comprising:

• a divergent seal body having a multiple of intakes arranged downstream of a hinge axis, said multiple of intakes communicate with a longitudinal cooling airflow channel within said divergent seal body, said longitudinal cooling airflow channel in communication with a multiple of edge channels along a longitudinal side of said divergent seal body;
• and
• a spine mounted along a divergent seal longitudinal axis, said spine defines a flap position guide.
