Abstract
A gas turbine engine includes a fan section, a heat exchanger, and inlet door. The fan section is configured to generate an airflow. The heat exchanger is configured to transfer heat from a thermal management system to the airflow. The inlet door is configured to modulate the airflow to the heat exchanger.
Claims22
An apparatus comprising:
- a fan section configured to generate an airflow;
- a heat exchanger configured to transfer heat from a thermal management system to the airflow;
- and
- an inlet door configured to modulate the airflow to the heat exchanger,
- wherein the inlet door includes a housing and is configured to operate in a fully modulated state with a first opening partially exposed outside of the housing, a second opening partially exposed outside of the housing, and a third opening exposed to an inlet duct of the heat exchanger.
