Integrated duct design for an unmanned aerial vehicle

摘要

A ducted fan air vehicle having increased storage capacity inside the duct for equipment and electronics provides improved airflow and fan efficiency over ducted fan air vehicles carrying cargo in external pods. The outside of the duct may extend outwardly to allow equipment and electronics to be stored inside the duct in storage areas located at intervals along the duct. The storage areas may form a square duct having a circular inside wall. Additionally, the storage areas may extend in the direction of the axis of rotation of the fan to provide additional storage above the lower lip of the duct.
