The duct reduces losses in thrust from the tip vortices of the fan, and varying the cross-section of the duct allows the designer to advantageously affect the velocity and pressure of the airflow according to Bernoulli s Principle. Ducted fan propulsion is used in aircraft, airboats, hovercraft and fan packs. 1.
