A lift fan (100) for use in short takeoff and vertical landing (STOVL) aircraft is disclosed and claimed. The lift fan (100) is driven by bleed air from a main engine of the aircraft being directed through an inlet (20) to fan tips (28) within a slot (48) in a housing (12), and may be stabilised in rotation by an electromagnet (50) or a polytetrafluoroethylene (PTFE) coating (92) within the slot (48). This eliminates the drag and torque on the main engine and reduces fuel cost and engine wear.
