The invention relates to a duct for a vehicle, comprising: an elongate passageway (212) defined by at least one wall (217), the passageway (212) having first and second ends relative to the longitudinal axis of the passageway (212); a non-annular inlet (216) at the first end of the passageway for receiving a first fluid flow from the boundary layer of the vehicle when in use; and, an annular outlet (226, 228) at the second end of the passageway (212) having an radially inner circumferential wall and a radially outer circumferential wall, the annular outlet (226, 228) being in fluid communication with a propulsive unit when in use, wherein the radially inner and outer circumferential walls extend continuously to the inlet (216).
