Abstract
Systems and methods for aircraft brake cooling are described. A system may include an air hose configured to intake pressurized air at a first end of the air hose from an aircraft propulsor. A nozzle at a second end of the air hose may be configured to exit the pressurized air through the air hose to a braking system. An actuator may be configured to allow the pressurized air to flow through the air hose or prevent the pressurized air from flowing through the air hose.
Claims20
A system comprising:
- an air hose configured to intake pressurized air at a first end of the air hose from an aircraft propulsor;
- a nozzle at a second end of the air hose and configured to exit the pressurized air through the air hose to a braking system;
- and
- an actuator configured to allow the pressurized air to flow through the air hose or prevent the pressurized air from flowing through the air hose;
- wherein the actuator is configured to be actuated by a controller to allow the pressurized air to flow upon determining by the controller that each of one or more first conditions is satisfied, the one or more first conditions comprising a condition that a first predetermined amount of time has elapsed after an event which is at least one of:
- aircraft wheels touching down, and/or aircraft brakes being applied, wherein the first predetermined amount of time is sufficient to allow the brakes to warm up before the pressurized air is allowed to flow.
3 more elements
A method comprising:
- capturing pressurized air from an aircraft propulsor;
- flowing the pressurized air to a braking system;
- and
- applying the pressurized air to the braking system, thus removing heat generated from brake application with the applied pressurized air;
- wherein the pressurized air is allowed to flow by a controller upon determining that each of one or more first conditions is satisfied, the one or more first conditions comprising a condition that a first predetermined amount of time has elapsed after an event which is at least one of:
- aircraft wheels touching down, and/or aircraft brakes being applied, wherein the first predetermined amount of time allows the brakes to warm up before the pressurized air is allowed to flow.
