ABSTRACT:
Divergent flaps of an axisymmetric exhaust nozzle include a hot inner gas path wall spaced from an outer wall to define a cooling fluid channel therebetween along the length of the flap from the upstream end of the flap near the divergent nozzle throat to near the downstream end of the flap. A slot or other opening in the flap inner wall at or just downstream of the nozzle throat communicates with the upstream end of the channel. Openings in the flap outer wall near the downstream end of the flap provide communication between the channel and external ambient air at a higher pressure than the gas at the nozzle throat. Ambient air thus travels upstream through the channel, convectively cooling the hot inner wall and exits through the slot in the inner wall at or near the throat to film cool the gas path side of the inner wall.
