Ducted rotor

Als Mantelpropeller (englisch ducted fan) wird eine Antriebseinrichtung bezeichnet, bei der. Beim Mantelpropeller wird der Propeller ( Rotor ) mit einem profilierten Mantelring umgeben. Im Vergleich zum nicht ummantelten, „ freifahrenden“ . In some cases, a shrouded rotor can be more efficient than an open rotor.

The improved performance is mainly because the outward flow is less.
