Abstract
A system for reducing debris in a gas turbine engine includes a component that defines a component cooling channel for receiving a cooling airflow. The system also includes a casing at least partially enclosing the component. The system also includes a debris evacuation door coupled to the casing and having an open state in which the debris can exit the casing and a closed state.
Claims19
A system for reducing debris in a gas turbine engine comprising:
- a component that defines a component cooling channel for receiving a cooling airflow;
- a casing at least partially enclosing the component;
- and
- a debris evacuation door coupled to the casing and having an open state in which the debris can exit the casing and a closed state,
- wherein the gas turbine engine includes an axis and wherein the debris evacuation door is axially aligned with an opening to the component.

A system for reducing debris in a gas turbine engine comprising:
- a component defining a component cooling channel for receiving a cooling airflow;
- a casing at least partially enclosing the component;
- a debris evacuation door coupled to the casing and having an open state in which debris can exit the casing and a closed state;
- an input device configured to receive user input;
- and
- a controller coupled to the input device and configured to control the debris evacuation door to switch from the open state to the closed state and to switch from the closed state to the open state based on the user input.

A method for removing debris from a turbine section of a gas turbine engine comprising:
- determining, by a controller, that the debris should be removed from the turbine section of the gas turbine engine;
- controlling, by the controller, a debris evacuation door coupled to a casing of the gas turbine engine to be in an open state in which the debris can exit the casing in response to determining that the debris should be removed;
- and
- controlling, by the controller, the debris evacuation door to be in a closed state in response to at least one of receiving a user input or expiration of a predetermined amount of time.
