Ducted fan cross section
WebDucted fans, or shrouded propellers, hold promise as a devices for high static thrust propulsion systems. When compared to an isolated propeller of the same diameter and … WebStatic pressure is the measure of the potential energy of a unit of air in the particular cross section of a duct. Air pressure on the duct wall is considered static. Imagine a fan blowing into a completely closed duct; it will create only static pressure because there is no air flow through the duct.
