Abstract
An environmental control system bleed cooling system including bleed air from the environmental control system bleed air system; a heat exchanger fluidly coupled between the environmental control system bleed air system and a gas turbine engine; and ambient cooling air fluidly coupled with the heat exchanger, wherein the ambient cooling air is configured to remove thermal energy from the bleed air flowing through the heat exchanger.
Claims18
An environmental control system comprising:
- bleed air from a bleed air system of the environmental control system;
- a heat exchanger fluidly coupled between the bleed air system and a gas turbine engine;
- ambient cooling air fluidly coupled with the heat exchanger, wherein the ambient cooling air is configured to remove thermal energy from the bleed air flowing through the heat exchanger;
- wherein the heat exchanger is located within a pylon structure, the pylon structure in operative communication with an aircraft and the gas turbine engine;
- and
- wherein the bleed air is fluidly coupled between the heat exchanger and a tail cone of the gas turbine engine.
An aircraft environmental control bleed cooling system comprising:
- a pylon structure in operative communication between the aircraft and a gas turbine engine;
- a heat exchanger located within the pylon structure;
- an aircraft environmental control system bleed air system bleed air fluidly coupled upstream of the heat exchanger;
- a gas turbine engine component fluidly coupled with bleed air from the environmental control system bleed air system downstream of the heat exchanger;
- ambient cooling air fluidly coupled with the heat exchanger, wherein the ambient cooling air is configured to remove thermal energy from the bleed air from the environmental control system bleed air system flowing through the heat exchanger;
- and
- the bleed air of the environmental control system bleed air system is fluidly coupled between the heat exchanger and electronics located within a tail cone of the gas turbine engine.
