A ducted fan is a propulsion adjustment whereby a fan, which is a blazon of propeller, is army aural a annular close or duct. The aqueduct reduces losses in advance from the tip vortices of the fan, and capricious the array of the aqueduct allows the artist to advantageously affect the acceleration and burden of the airflow according to Bernoulli's Principle. Ducted fan propulsion is acclimated in aircraft, airships, airboats, hovercraft and fan packs.1
