ABSTRACT:
A high-speed transportation system employing a pivotally supported guide rail structure made of sections connected by expansion joints, with a self-propelled airplane automatically steered to fly along the guide rail with minimum force therebetween by a control system that is inclusive of displacement sensors associated with air bearings coupling the aircraft to the guide rail. A wheeled construction having wheels that can be driven, braked or free wheeling is provided that is automatically lowered or maintained in a lowered position contacting the guide rail whenever the aircraft lacks flying speed or the wheels are either driven or braked. The air bearings urge centering of the rail both vertically and laterally with respect thereto. Flight stability of the aircraft is enhanced by the provision of a ground effect bed, and gust spoilers, with the latter additionally functioning as a noise abatement device.
