Abstract
An improved transportation system is provided by which vehicles may be propelled along the top of a duct on a cushion of pressurized air. The duct is provided with a grating on its upper surface through which the pressurized air is emitted from the interior of the duct, and a longitudinal slot extends along the grating. The lower surface of the grating is normally closed by a flexible belt which extends along the interior of the duct. The belt is depressed down from the grating as the vehicle moves along the top of the duct to permit air pressure in the duct to escape through the grating and thus support the vehicle on a cushion of air. At least one vane is attached to a carriage, the vane being supported on the lower end of an arm which depends from the vehicle and extends down through the slot into the interior of the duct. The vane extends across the interior of the duct. A pressure differential created within the duct on opposite sides of the vane serve to propel the vehicle along the top of the duct.
