ABSTRACT:
An exhaust nozzle has main flaps with seals therebetween. Each flap and seal is constructed having inner and outer members which cooperate to form a liner for cooling air therethrough which extends substantially around the entire circumference of the liner. This arrangement provides a construction for cooling airflow which is compatible with nozzle diameter change. While the seal basically floats, it is maintained in place longitudinally and circumferentially so that leakage does not occur between the flaps. The coolant flows through the flaps and seals of the convergent section of the nozzle and is directed over the divergent section of the nozzle.
