  • Publication number: 20110308422
    Abstract: A vehicle track including a soft porous material and a vehicle which rides on the track by skiing cm the soft porous material. The vehicle has a large ski surface that rides on the soft porous material, supporting the weight of the vehicle at high speeds. Air within the soft porous material supplies most of the lift needed to support the train, Qniy a small amount of the support is provided by the structure of the porous material itself when the vehicle is in motion. As a result, the friction between the soft porous material and the ski surface may also be exceedingly small. To increase the amount of lift provided by the soft porous material it can be contained within a channel having impermeable sides and bottom. If the ski surface is substantially the same width as the channel, the impermeable sides prevent the air from escaping on either side of die ski surface. Accordingly, the trapped air contributes to greatly enhanced lift force.

  • Patent number: 4061089
    Abstract: A land transportation system for a vehicle that is supported and guided by air bearings. The vehicle requires no driver or motorman because a guideway determines the direction of travel, except at switch-points in the network. The vehicle is propelled by a linear synchronous motor when on the guideway. The linear synchronous motor primary is embedded in the guideway. A linear inductor alternator provides on-board electric power. A pair of linear induction motors are used to accelerate the vehicle from a station stop up to guideway synchronous speed, to provide a magnetically attractive element to permit switching in guideway tracks, and to provide dynamic braking when stopping at the destination station.
