Beschreibung
Zusammenfassung:	A fan assembly (10) includes a shrouded fan rotor (18) having a plurality of fan blades (22) extending from a rotor hub (24) and rotatable about a central axis (20) of the fan assembly, and a fan shroud (26) extending circumferentially around the fan rotor (18) and secured to an outer tip diameter of the plurality of fan blades (22). A fan casing (16) encloses the shrouded fan rotor (18). The fan casing (16) defines a fan inlet (30) of the fan assembly and includes an inlet extension (54) at an outer diameter of the fan casing, extending axially upstream of a conventional bell mouth inlet (58), relative to a direction of airflow through the shrouded fan rotor (18).
