A vehicle, comprising: a vehicle frame; a duct carried by the vehicle frame with the longitudinal axis of the duct perpendicular to the longitudinal axis of the vehicle frame; a propeller rotatably mounted within the duct about the longitudinal axis of the duct to force an ambient fluid through from an inlet at the upper end of the duct through an exit at the lower end of the duct, and thereby produce an upward lift force applied to the vehicle; a first plurality of substantially parallel, spaced vanes non-pivotally mounted across at least the inlet end of the duct; and fluidic means for affecting the ambient fluid flow around the vanes to generate horizontal force components to the lift force applied to the vehicle.
