Abstract
A cooling system for a gas turbine engine may comprise a heat exchanger configured to receive a cooling airflow. The heat exchanger may receive the cooling flow at a cooling flow input of the heat exchanger and output the cooling airflow at an exhaust output of the heat exchanger. An exhaust distribution manifold may be fluidly coupled to the exhaust output of the heat exchanger. The exhaust distribution manifold may define a plurality of openings.
Claims19
A cooling system for a gas turbine engine, comprising:
- a heat exchanger configured to receive a cooling airflow, wherein the heat exchanger is configured to receive the cooling airflow at a cooling flow input of the heat exchanger, and wherein the heat exchanger is configured to output the cooling airflow at a first exhaust output of the heat exchanger;
- a first exhaust distribution manifold fluidly coupled to the first exhaust output of the heat exchanger, wherein the first exhaust distribution manifold defines a plurality of first openings;
- and
- a second exhaust distribution manifold fluidly coupled to a second exhaust output of the heat exchanger, wherein the second exhaust distribution manifold defines a plurality of second openings.
A gas turbine engine, comprising:
- an inner engine case structure;
- an outer engine case structure radially outward of the inner engine case structure;
- and
- a cooling system located at least partially between the inner engine case structure and the outer engine case structure, the cooling system comprising:
- a first heat exchanger configured to receive a cooling airflow;
- and
- a first exhaust distribution manifold fluidly coupled to a first exhaust output of the first heat exchanger, wherein the first exhaust distribution manifold defines a plurality of first openings, and wherein a distal end of the first exhaust distribution manifold is circumferentially offset from an inlet end of the first exhaust distribution manifold.
An exhaust distribution manifold configured to be fluidly coupled to an exhaust output of a heat exchanger, the exhaust distribution manifold comprising:
- a first end defining an inlet of the exhaust distribution manifold and having a first diameter;
- a second end located opposite the first end and have a second diameter less than the first diameter, wherein the second end is circumferentially offset from the first end;
- and
- a plurality of openings formed between the first end and the second end, wherein the plurality of openings are formed over approximately 100° of a circumference of the exhaust distribution manifold, and wherein approximately 260° of the circumference of the exhaust distribution manifold is devoid of openings.
