Cooling Apparatus For An Exhaust Nozzle Of A Gas Turbine Engine
US Patent:
4203286, May 20, 1980
Filed:
Oct 30, 1978
Appl. No.:
5/956305
Inventors:
Robert E. Warburton - Lake Park FL
Assignee:
The United States of America as represented by the Secretary of the Air
Force - Washington DC
Force - Washington DC
International Classification:
F02K 112
US Classification:
60266
Abstract:
A cooling control system for a convergent-divergent gas turbine exhaust nozzle which permits automatic ducting of cooling air during the augmented mode of engine operation. The convergent flaps of the nozzle have longitudinal ducts embedded therein with a pair of openings near the aft extreme of each of the convergent flaps and openings located in the forward half of the convergent flaps. The convergent seals overlap the convergent flaps and are slideably mounted for positioning over the aft openings on the flaps. A positive pressure is generated under the convergent flap liner and seal liner when the convergent seal is opened to allow cooling air to be ducted through the flap. The positive pressure forces the convergent flap and seal liners up toward the center line of the nozzle.
Cooled Exhaust Nozzle Flaps
US Patent:
4544098, Oct 1, 1985
Filed:
Dec 27, 1982
Appl. No.:
6/453186
Inventors:
Robert E. Warburton - Lake Park FL
Assignee:
United Technologies Corporation - Hartford CT
International Classification:
B64C 1506
US Classification:
2391273
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.
