Abstract
A cooling arrangement for the trailing edge of a nozzle flap 18 has a trailing edge liner 30,54 and a baffle plate 32,55. Air from plenum 22 passes through openings 38,54 to cool the trailing edge liner. Expansion of the nozzle liner 18 causes abutment seal 52 to open, increasing cooling air in proportion to the temperature of the nozzle liner.
