Abstract
An aircraft and its centrifugal fan. The centrifugal fan of this invention has a plurality of airflow ducts circumferentially arranged around the rotational axis of the centrifugal fan. Each airflow duct is provided with a damper that opens under the thrust of airflow when air flows outward through the duct and automatically closes when the airflow ceases. The centrifugal fan of this invention addresses the protection issue at the outlet of aircraft centrifugal fans, reduces the impact of wind resistance, improves the reliability of the power unit, and achieves a higher protection level.
